COVID-19 Pandemic

By: History.com Editors

Updated: March 11, 2024 | Original: April 25, 2023

The outbreak of the infectious respiratory disease known as COVID-19 triggered one of the deadliest pandemics in modern history. COVID-19 claimed nearly 7 million lives worldwide. In the United States, deaths from COVID-19 exceeded 1.1 million, nearly twice the American death toll from the 1918 flu pandemic . The COVID-19 pandemic also took a heavy toll economically, politically and psychologically, revealing deep divisions in the way that Americans viewed the role of government in a public health crisis, particularly vaccine mandates. While the United States downgraded its “national emergency” status over the pandemic on May 11, 2023, the full effects of the COVID-19 pandemic will reverberate for decades.

A New Virus Breaks Out in Wuhan, China

In December 2019, the China office of the World Health Organization (WHO) received news of an isolated outbreak of a pneumonia-like virus in the city of Wuhan. The virus caused high fevers and shortness of breath, and the cases seemed connected to the Huanan Seafood Wholesale Market in Wuhan, which was closed by an emergency order on January 1, 2020.

After testing samples of the unknown virus, the WHO identified it as a novel type of coronavirus similar to the deadly SARS virus that swept through Asia from 2002-2004. The WHO named this new strain SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). The first Chinese victim of SARS-CoV-2 died on January 11, 2020.

Where, exactly, the novel virus originated has been hotly debated. There are two leading theories. One is that the virus jumped from animals to humans, possibly carried by infected animals sold at the Wuhan market in late 2019. A second theory claims the virus escaped from the Wuhan Institute of Virology, a research lab that was studying coronaviruses. U.S. intelligence agencies maintain that both origin stories are “plausible.”

The First COVID-19 Cases in America

The WHO hoped that the virus outbreak would be contained to Wuhan, but by mid-January 2020, infections were reported in Thailand, Japan and Korea, all from people who had traveled to China.

On January 18, 2020, a 35-year-old man checked into an urgent care center near Seattle, Washington. He had just returned from Wuhan and was experiencing a fever, nausea and vomiting. On January 21, he was identified as the first American infected with SARS-CoV-2.

In reality, dozens of Americans had contracted SARS-CoV-2 weeks earlier, but doctors didn’t think to test for a new type of virus. One of those unknowingly infected patients died on February 6, 2020, but her death wasn’t confirmed as the first American casualty until April 21.

On February 11, 2020, the WHO released a new name for the disease causing the deadly outbreak: Coronavirus Disease 2019 or COVID-19. By mid-March 2020, all 50 U.S. states had reported at least one positive case of COVID-19, and nearly all of the new infections were caused by “community spread,” not by people who contracted the disease while traveling abroad. 

At the same time, COVID-19 had spread to 114 countries worldwide, killing more than 4,000 people and infecting hundreds of thousands more. On March 11, the WHO made it official and declared COVID-19 a pandemic.

The World Shuts Down

Pandemics are expected in a globally interconnected world, so emergency plans were in place. In the United States, health officials at the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) set in motion a national response plan developed for flu pandemics.

State by state and city by city, government officials took emergency measures to encourage “ social distancing ,” one of the many new terms that became part of the COVID-19 vocabulary. Travel was restricted. Schools and churches were closed. With the exception of “essential workers,” all offices and businesses were shuttered. By early April 2020, more than 316 million Americans were under a shelter-in-place or stay-at-home order.

With more than 1,000 deaths and nearly 100,000 cases, it was clear by April 2020 that COVID-19 was highly contagious and virulent. What wasn’t clear, even to public health officials, was how individuals could best protect themselves from COVID-19. In the early weeks of the outbreak, the CDC discouraged people from buying face masks, because officials feared a shortage of masks for doctors and hospital workers.

By April 2020, the CDC revised its recommendations, encouraging people to wear masks in public, to socially distance and to wash hands frequently. President Donald Trump undercut the CDC recommendations by emphasizing that masking was voluntary and vowing not to wear a mask himself. This was just the beginning of the political divisions that hobbled the COVID-19 response in America.

Global Financial Markets Collapse

In the early months of the COVID-19 pandemic, with billions of people worldwide out of work, stuck at home, and fretting over shortages of essential items like toilet paper , global financial markets went into a tailspin.

In the United States, share prices on the New York Stock Exchange plummeted so quickly that the exchange had to shut down trading three separate times. The Dow Jones Industrial Average eventually lost 37 percent of its value, and the S&P 500 was down 34 percent.

Business closures and stay-at-home orders gutted the U.S. economy. The unemployment rate skyrocketed, particularly in the service sector (restaurant and other retail workers). By May 2020, the U.S. unemployment rate reached 14.7 percent, the highest jobless rate since the Great Depression . 

All across America, households felt the pinch of lost jobs and lower wages. Food insecurity reached a peak by December 2020 with 30 million American adults—a full 14 percent—reporting that their families didn’t get enough to eat in the past week.

The economic effects of the COVID-19 pandemic, like its health effects, weren’t experienced equally. Black, Hispanic and Native Americans suffered from unemployment and food insecurity at significantly higher rates than white Americans. 

Congress tried to avoid a complete economic collapse by authorizing a series of COVID-19 relief packages in 2020 and 2021, which included direct stimulus checks for all American families.

The Race for a Vaccine

A new vaccine typically takes 10 to 15 years to develop and test, but the world couldn’t wait that long for a COVID-19 vaccine. The U.S. Department of Health and Human Services (HHS) under the Trump administration launched “ Operation Warp Speed ,” a public-private partnership which provided billions of dollars in upfront funding to pharmaceutical companies to rapidly develop vaccines and conduct clinical trials.

The first clinical trial for a COVID-19 vaccine was announced on March 16, 2020, only days after the WHO officially classified COVID-19 as a pandemic. The vaccines developed by Moderna and Pfizer were the first ever to employ messenger RNA, a breakthrough technology. After large-scale clinical trials, both vaccines were found to be greater than 95 percent effective against infection with COVID-19.

A nurse from New York officially became the first American to receive a COVID-19 vaccine on December 14, 2020. Ten days later, more than 1 million vaccines had been administered, starting with healthcare workers and elderly residents of nursing homes. As the months rolled on, vaccine availability was expanded to all American adults, and then to teenagers and all school-age children.

By the end of the pandemic in early 2023, more than 670 million doses of COVID-19 vaccines had been administered in the United States at a rate of 203 doses per 100 people. Approximately 80 percent of the U.S. population received at least one COVID-19 shot, but vaccination rates were markedly lower among Black, Hispanic and Native Americans.

COVID-19 Deaths Heaviest Among Elderly and People of Color

In America, the COVID-19 pandemic impacted everyone’s lives, but those who died from the disease were far more likely to be older and people of color.

Of the more than 1.1 million COVID deaths in the United States, 75 percent were individuals who were 65 or older. A full 93 percent of American COVID-19 victims were 50 or older. Throughout the emergence of COVID-19 variants and the vaccine rollouts, older Americans remained the most at-risk for being hospitalized and ultimately dying from the disease.

Black, Hispanic and Native Americans were also at a statistically higher risk of developing life-threatening COVID-19 systems and succumbing to the disease. For example, Black and Hispanic Americans were twice as likely to be hospitalized from COVID-19 than white Americans. The COVID-19 pandemic shined light on the health disparities between racial and ethnic groups driven by systemic racism and lower access to healthcare.

Mental health also worsened during the COVID-19 pandemic. The anxiety of contracting the disease, and the stresses of being unemployed or confined at home, led to unprecedented numbers of Americans reporting feelings of depression and suicidal ideation.

A Time of Social & Political Upheaval

In the United States, the three long years of the COVID-19 pandemic paralleled a time of heightened political contention and social upheaval.

When George Floyd was killed by Minneapolis police on May 25, 2020, it sparked nationwide protests against police brutality and energized the Black Lives Matter movement. Because so many Americans were out of work or home from school due to COVID-19 shutdowns, unprecedented numbers of people from all walks of life took to the streets to demand reforms.

Instead of banding together to slow the spread of the disease, Americans became sharply divided along political lines in their opinions of masking requirements, vaccines and social distancing.

By March 2024, in signs that the pandemic was waning, the CDC issued new guidelines for people who were recovering from COVID-19. The agency said those infected with the virus no longer needed to remain isolated for five days after symptoms. And on March 10, 2024, the Johns Hopkins Coronavirus Resource Center stopped collecting data for its highly referenced COVID-19 dashboard.

Still, an estimated 17 percent of U.S. adults reported having experienced symptoms of long COVID, according to the Household Pulse Survey. The medical community is still working to understand the causes behind long COVID, which can afflict a patient for weeks, months or even years.

How to Write About Coronavirus in a College Essay

Students can share how they navigated life during the coronavirus pandemic in a full-length essay or an optional supplement.

Writing About COVID-19 in College Essays

Experts say students should be honest and not limit themselves to merely their experiences with the pandemic.

The global impact of COVID-19, the disease caused by the novel coronavirus, means colleges and prospective students alike are in for an admissions cycle like no other. Both face unprecedented challenges and questions as they grapple with their respective futures amid the ongoing fallout of the pandemic.

Colleges must examine applicants without the aid of standardized test scores for many – a factor that prompted many schools to go test-optional for now . Even grades, a significant component of a college application, may be hard to interpret with some high schools adopting pass-fail classes last spring due to the pandemic. Major college admissions factors are suddenly skewed.

"I can't help but think other (admissions) factors are going to matter more," says Ethan Sawyer, founder of the College Essay Guy, a website that offers free and paid essay-writing resources.

College essays and letters of recommendation , Sawyer says, are likely to carry more weight than ever in this admissions cycle. And many essays will likely focus on how the pandemic shaped students' lives throughout an often tumultuous 2020.

But before writing a college essay focused on the coronavirus, students should explore whether it's the best topic for them.

Writing About COVID-19 for a College Application

Much of daily life has been colored by the coronavirus. Virtual learning is the norm at many colleges and high schools, many extracurriculars have vanished and social lives have stalled for students complying with measures to stop the spread of COVID-19.

"For some young people, the pandemic took away what they envisioned as their senior year," says Robert Alexander, dean of admissions, financial aid and enrollment management at the University of Rochester in New York. "Maybe that's a spot on a varsity athletic team or the lead role in the fall play. And it's OK for them to mourn what should have been and what they feel like they lost, but more important is how are they making the most of the opportunities they do have?"

That question, Alexander says, is what colleges want answered if students choose to address COVID-19 in their college essay.

But the question of whether a student should write about the coronavirus is tricky. The answer depends largely on the student.

"In general, I don't think students should write about COVID-19 in their main personal statement for their application," Robin Miller, master college admissions counselor at IvyWise, a college counseling company, wrote in an email.

"Certainly, there may be exceptions to this based on a student's individual experience, but since the personal essay is the main place in the application where the student can really allow their voice to be heard and share insight into who they are as an individual, there are likely many other topics they can choose to write about that are more distinctive and unique than COVID-19," Miller says.

Opinions among admissions experts vary on whether to write about the likely popular topic of the pandemic.

"If your essay communicates something positive, unique, and compelling about you in an interesting and eloquent way, go for it," Carolyn Pippen, principal college admissions counselor at IvyWise, wrote in an email. She adds that students shouldn't be dissuaded from writing about a topic merely because it's common, noting that "topics are bound to repeat, no matter how hard we try to avoid it."

Above all, she urges honesty.

"If your experience within the context of the pandemic has been truly unique, then write about that experience, and the standing out will take care of itself," Pippen says. "If your experience has been generally the same as most other students in your context, then trying to find a unique angle can easily cross the line into exploiting a tragedy, or at least appearing as though you have."

But focusing entirely on the pandemic can limit a student to a single story and narrow who they are in an application, Sawyer says. "There are so many wonderful possibilities for what you can say about yourself outside of your experience within the pandemic."

He notes that passions, strengths, career interests and personal identity are among the multitude of essay topic options available to applicants and encourages them to probe their values to help determine the topic that matters most to them – and write about it.

That doesn't mean the pandemic experience has to be ignored if applicants feel the need to write about it.

Writing About Coronavirus in Main and Supplemental Essays

Students can choose to write a full-length college essay on the coronavirus or summarize their experience in a shorter form.

To help students explain how the pandemic affected them, The Common App has added an optional section to address this topic. Applicants have 250 words to describe their pandemic experience and the personal and academic impact of COVID-19.

"That's not a trick question, and there's no right or wrong answer," Alexander says. Colleges want to know, he adds, how students navigated the pandemic, how they prioritized their time, what responsibilities they took on and what they learned along the way.

If students can distill all of the above information into 250 words, there's likely no need to write about it in a full-length college essay, experts say. And applicants whose lives were not heavily altered by the pandemic may even choose to skip the optional COVID-19 question.

"This space is best used to discuss hardship and/or significant challenges that the student and/or the student's family experienced as a result of COVID-19 and how they have responded to those difficulties," Miller notes. Using the section to acknowledge a lack of impact, she adds, "could be perceived as trite and lacking insight, despite the good intentions of the applicant."

To guard against this lack of awareness, Sawyer encourages students to tap someone they trust to review their writing , whether it's the 250-word Common App response or the full-length essay.

Experts tend to agree that the short-form approach to this as an essay topic works better, but there are exceptions. And if a student does have a coronavirus story that he or she feels must be told, Alexander encourages the writer to be authentic in the essay.

"My advice for an essay about COVID-19 is the same as my advice about an essay for any topic – and that is, don't write what you think we want to read or hear," Alexander says. "Write what really changed you and that story that now is yours and yours alone to tell."

Sawyer urges students to ask themselves, "What's the sentence that only I can write?" He also encourages students to remember that the pandemic is only a chapter of their lives and not the whole book.

Miller, who cautions against writing a full-length essay on the coronavirus, says that if students choose to do so they should have a conversation with their high school counselor about whether that's the right move. And if students choose to proceed with COVID-19 as a topic, she says they need to be clear, detailed and insightful about what they learned and how they adapted along the way.

"Approaching the essay in this manner will provide important balance while demonstrating personal growth and vulnerability," Miller says.

Pippen encourages students to remember that they are in an unprecedented time for college admissions.

"It is important to keep in mind with all of these (admission) factors that no colleges have ever had to consider them this way in the selection process, if at all," Pippen says. "They have had very little time to calibrate their evaluations of different application components within their offices, let alone across institutions. This means that colleges will all be handling the admissions process a little bit differently, and their approaches may even evolve over the course of the admissions cycle."

I Thought We’d Learned Nothing From the Pandemic. I Wasn’t Seeing the Full Picture

M y first home had a back door that opened to a concrete patio with a giant crack down the middle. When my sister and I played, I made sure to stay on the same side of the divide as her, just in case. The 1988 film The Land Before Time was one of the first movies I ever saw, and the image of the earth splintering into pieces planted its roots in my brain. I believed that, even in my own backyard, I could easily become the tiny Triceratops separated from her family, on the other side of the chasm, as everything crumbled into chaos.

Some 30 years later, I marvel at the eerie, unexpected ways that cartoonish nightmare came to life – not just for me and my family, but for all of us. The landscape was already covered in fissures well before COVID-19 made its way across the planet, but the pandemic applied pressure, and the cracks broke wide open, separating us from each other physically and ideologically. Under the weight of the crisis, we scattered and landed on such different patches of earth we could barely see each other’s faces, even when we squinted. We disagreed viciously with each other, about how to respond, but also about what was true.

Recently, someone asked me if we’ve learned anything from the pandemic, and my first thought was a flat no. Nothing. There was a time when I thought it would be the very thing to draw us together and catapult us – as a capital “S” Society – into a kinder future. It’s surreal to remember those early days when people rallied together, sewing masks for health care workers during critical shortages and gathering on balconies in cities from Dallas to New York City to clap and sing songs like “Yellow Submarine.” It felt like a giant lightning bolt shot across the sky, and for one breath, we all saw something that had been hidden in the dark – the inherent vulnerability in being human or maybe our inescapable connectedness .

But it turns out, it was just a flash. The goodwill vanished as quickly as it appeared. A couple of years later, people feel lied to, abandoned, and all on their own. I’ve felt my own curiosity shrinking, my willingness to reach out waning , my ability to keep my hands open dwindling. I look out across the landscape and see selfishness and rage, burnt earth and so many dead bodies. Game over. We lost. And if we’ve already lost, why try?

Still, the question kept nagging me. I wondered, am I seeing the full picture? What happens when we focus not on the collective society but at one face, one story at a time? I’m not asking for a bow to minimize the suffering – a pretty flourish to put on top and make the whole thing “worth it.” Yuck. That’s not what we need. But I wondered about deep, quiet growth. The kind we feel in our bodies, relationships, homes, places of work, neighborhoods.

Like a walkie-talkie message sent to my allies on the ground, I posted a call on my Instagram. What do you see? What do you hear? What feels possible? Is there life out here? Sprouting up among the rubble? I heard human voices calling back – reports of life, personal and specific. I heard one story at a time – stories of grief and distrust, fury and disappointment. Also gratitude. Discovery. Determination.

Among the most prevalent were the stories of self-revelation. Almost as if machines were given the chance to live as humans, people described blossoming into fuller selves. They listened to their bodies’ cues, recognized their desires and comforts, tuned into their gut instincts, and honored the intuition they hadn’t realized belonged to them. Alex, a writer and fellow disabled parent, found the freedom to explore a fuller version of herself in the privacy the pandemic provided. “The way I dress, the way I love, and the way I carry myself have both shrunk and expanded,” she shared. “I don’t love myself very well with an audience.” Without the daily ritual of trying to pass as “normal” in public, Tamar, a queer mom in the Netherlands, realized she’s autistic. “I think the pandemic helped me to recognize the mask,” she wrote. “Not that unmasking is easy now. But at least I know it’s there.” In a time of widespread suffering that none of us could solve on our own, many tended to our internal wounds and misalignments, large and small, and found clarity.

I wonder if this flourishing of self-awareness is at least partially responsible for the life alterations people pursued. The pandemic broke open our personal notions of work and pushed us to reevaluate things like time and money. Lucy, a disabled writer in the U.K., made the hard decision to leave her job as a journalist covering Westminster to write freelance about her beloved disability community. “This work feels important in a way nothing else has ever felt,” she wrote. “I don’t think I’d have realized this was what I should be doing without the pandemic.” And she wasn’t alone – many people changed jobs , moved, learned new skills and hobbies, became politically engaged.

Perhaps more than any other shifts, people described a significant reassessment of their relationships. They set boundaries, said no, had challenging conversations. They also reconnected, fell in love, and learned to trust. Jeanne, a quilter in Indiana, got to know relatives she wouldn’t have connected with if lockdowns hadn’t prompted weekly family Zooms. “We are all over the map as regards to our belief systems,” she emphasized, “but it is possible to love people you don’t see eye to eye with on every issue.” Anna, an anti-violence advocate in Maine, learned she could trust her new marriage: “Life was not a honeymoon. But we still chose to turn to each other with kindness and curiosity.” So many bonds forged and broken, strengthened and strained.

Instead of relying on default relationships or institutional structures, widespread recalibrations allowed for going off script and fortifying smaller communities. Mara from Idyllwild, Calif., described the tangible plan for care enacted in her town. “We started a mutual-aid group at the beginning of the pandemic,” she wrote, “and it grew so quickly before we knew it we were feeding 400 of the 4000 residents.” She didn’t pretend the conditions were ideal. In fact, she expressed immense frustration with our collective response to the pandemic. Even so, the local group rallied and continues to offer assistance to their community with help from donations and volunteers (many of whom were originally on the receiving end of support). “I’ve learned that people thrive when they feel their connection to others,” she wrote. Clare, a teacher from the U.K., voiced similar conviction as she described a giant scarf she’s woven out of ribbons, each representing a single person. The scarf is “a collection of stories, moments and wisdom we are sharing with each other,” she wrote. It now stretches well over 1,000 feet.

A few hours into reading the comments, I lay back on my bed, phone held against my chest. The room was quiet, but my internal world was lighting up with firefly flickers. What felt different? Surely part of it was receiving personal accounts of deep-rooted growth. And also, there was something to the mere act of asking and listening. Maybe it connected me to humans before battle cries. Maybe it was the chance to be in conversation with others who were also trying to understand – what is happening to us? Underneath it all, an undeniable thread remained; I saw people peering into the mess and narrating their findings onto the shared frequency. Every comment was like a flare into the sky. I’m here! And if the sky is full of flares, we aren’t alone.

I recognized my own pandemic discoveries – some minor, others massive. Like washing off thick eyeliner and mascara every night is more effort than it’s worth; I can transform the mundane into the magical with a bedsheet, a movie projector, and twinkle lights; my paralyzed body can mother an infant in ways I’d never seen modeled for me. I remembered disappointing, bewildering conversations within my own family of origin and our imperfect attempts to remain close while also seeing things so differently. I realized that every time I get the weekly invite to my virtual “Find the Mumsies” call, with a tiny group of moms living hundreds of miles apart, I’m being welcomed into a pocket of unexpected community. Even though we’ve never been in one room all together, I’ve felt an uncommon kind of solace in their now-familiar faces.

Hope is a slippery thing. I desperately want to hold onto it, but everywhere I look there are real, weighty reasons to despair. The pandemic marks a stretch on the timeline that tangles with a teetering democracy, a deteriorating planet , the loss of human rights that once felt unshakable . When the world is falling apart Land Before Time style, it can feel trite, sniffing out the beauty – useless, firing off flares to anyone looking for signs of life. But, while I’m under no delusions that if we just keep trudging forward we’ll find our own oasis of waterfalls and grassy meadows glistening in the sunshine beneath a heavenly chorus, I wonder if trivializing small acts of beauty, connection, and hope actually cuts us off from resources essential to our survival. The group of abandoned dinosaurs were keeping each other alive and making each other laugh well before they made it to their fantasy ending.

After the monarch butterfly went on the endangered-species list, my friend and fellow writer Hannah Soyer sent me wildflower seeds to plant in my yard. A simple act of big hope – that I will actually plant them, that they will grow, that a monarch butterfly will receive nourishment from whatever blossoms are able to push their way through the dirt. There are so many ways that could fail. But maybe the outcome wasn’t exactly the point. Maybe hope is the dogged insistence – the stubborn defiance – to continue cultivating moments of beauty regardless. There is value in the planting apart from the harvest.

I can’t point out a single collective lesson from the pandemic. It’s hard to see any great “we.” Still, I see the faces in my moms’ group, making pancakes for their kids and popping on between strings of meetings while we try to figure out how to raise these small people in this chaotic world. I think of my friends on Instagram tending to the selves they discovered when no one was watching and the scarf of ribbons stretching the length of more than three football fields. I remember my family of three, holding hands on the way up the ramp to the library. These bits of growth and rings of support might not be loud or right on the surface, but that’s not the same thing as nothing. If we only cared about the bottom-line defeats or sweeping successes of the big picture, we’d never plant flowers at all.

Students’ Essays on Infectious Disease Prevention, COVID-19 Published Nationwide

As part of the BIO 173: Global Change and Infectious Disease course, Professor Fred Cohan assigns students to write an essay persuading others to prevent future and mitigate present infectious diseases. If students submit their essay to a news outlet—and it’s published—Cohan awards them with extra credit.

As a result of this assignment, more than 25 students have had their work published in newspapers across the United States. Many of these essays cite and applaud the University’s Keep Wes Safe campaign and its COVID-19 testing protocols.

Cohan, professor of biology and Huffington Foundation Professor in the College of the Environment (COE), began teaching the Global Change and Infectious Disease course in 2009, when the COE was established. “I wanted very much to contribute a course to what I saw as a real game-changer in Wesleyan’s interest in the environment. The course is about all the ways that human demands on the environment have brought us infectious diseases, over past millennia and in the present, and why our environmental disturbances will continue to bring us infections into the future.”

Over the years, Cohan learned that he can sustainably teach about 170 students every year without running out of interested students. This fall, he had 207. Although he didn’t change the overall structure of his course to accommodate COVID-19 topics, he did add material on the current pandemic to various sections of the course.

“I wouldn’t say that the population of the class increased tremendously as a result of COVID-19, but I think the enthusiasm of the students for the material has increased substantially,” he said.

To accommodate online learning, Cohan shaved off 15 minutes from his normal 80-minute lectures to allow for discussion sections, led by Cohan and teaching assistants. “While the lectures mostly dealt with biology, the discussions focused on how changes in behavior and policy can solve the infectious disease problems brought by human disturbance of the environment,” he said.

Based on student responses to an introspective exam question, Cohan learned that many students enjoyed a new hope that we could each contribute to fighting infectious disease. “They discovered that the solution to infectious disease is not entirely a waiting game for the right technologies to come along,” he said. “Many enjoyed learning about fighting infectious disease from a moral and social perspective. And especially, the students enjoyed learning about the ‘socialism of the microbe,’ how preventing and curing others’ infections will prevent others’ infections from becoming our own. The students enjoyed seeing how this idea can drive both domestic and international health policies.”

A sampling of the published student essays are below:

Alexander Giummo ’22 and Mike Dunderdale’s ’23  op-ed titled “ A National Testing Proposal: Let’s Fight Back Against COVID-19 ” was published in the Journal Inquirer in Manchester, Conn.

They wrote: “With an expansive and increased testing plan for U.S. citizens, those who are COVID-positive could limit the number of contacts they have, and this would also help to enable more effective contact tracing. Testing could also allow for the return of some ‘normal’ events, such as small social gatherings, sports, and in-person class and work schedules.

“We propose a national testing strategy in line with the one that has kept Wesleyan students safe this year. The plan would require a strong push by the federal government to fund the initiative, but it is vital to successful containment of the virus.

“Twice a week, all people living in the U.S. should report to a local testing site staffed with professionals where the anterior nasal swab Polymerase Chain Reaction (PCR) test, used by Wesleyan and supported by the Broad Institute, would be implemented.”

Kalyani Mohan ’22 and Kalli Jackson ’22 penned an essay titled “ Where Public Health Meets Politics: COVID-19 in the United States ,” which was published in Wesleyan’s Arcadia Political Review .

They wrote: “While the U.S. would certainly benefit from a strengthened pandemic response team and structural changes to public health systems, that alone isn’t enough, as American society is immensely stratified, socially and culturally. The politicization of the COVID-19 pandemic shows that individualism, libertarianism and capitalism are deeply ingrained in American culture, to the extent that Americans often blind to the fact community welfare can be equivalent to personal welfare. Pandemics are multifaceted, and preventing them requires not just a cultural shift but an emotional one amongst the American people, one guided by empathy—towards other people, different communities and the planet. Politics should be a tool, not a weapon against its people.”

Sydnee Goyer ’21 and Marcel Thompson’s ’22  essay “ This Flu Season Will Be Decisive in the Fight Against COVID-19 ” also was published in Arcadia Political Review .

“With winter approaching all around the Northern Hemisphere, people are preparing for what has already been named a “twindemic,” meaning the joint threat of the coronavirus and the seasonal flu,” they wrote. “While it is known that seasonal vaccinations reduce the risk of getting the flu by up to 60% and also reduce the severity of the illness after the contamination, additional research has been conducted in order to know whether or not flu shots could reduce the risk of people getting COVID-19. In addition to the flu shot, it is essential that people remain vigilant in maintaining proper social distancing, washing your hands thoroughly, and continuing to wear masks in public spaces.”

An op-ed titled “ The Pandemic Has Shown Us How Workplace Culture Needs to Change ,” written by Adam Hickey ’22 and George Fuss ’21, was published in Park City, Utah’s The Park Record .

They wrote: “One review of academic surveys (most of which were conducted in the United States) conducted in 2019 found that between 35% and 97% of respondents in those surveys reported having attended work while they were ill, often because of workplace culture or policy which generated pressure to do so. Choosing to ignore sickness and return to the workplace while one is ill puts colleagues at risk, regardless of the perceived severity of your own illness; COVID-19 is an overbearing reminder that a disease that may cause mild, even cold-like symptoms for some can still carry fatal consequences for others.

“A mandatory paid sick leave policy for every worker, ideally across the globe, would allow essential workers to return to work when necessary while still providing enough wiggle room for economically impoverished employees to take time off without going broke if they believe they’ve contracted an illness so as not to infect the rest of their workplace and the public at large.”

Women’s cross country team members and classmates Jane Hollander ’23 and Sara Greene ’23 wrote a sports-themed essay titled “ This Season, High School Winter Sports Aren’t Worth the Risk ,” which was published in Tap into Scotch Plains/Fanwood , based in Scotch Plains, N.J. Their essay focused on the risks high school sports pose on student-athletes, their families, and the greater community.

“We don’t propose cutting off sports entirely— rather, we need to be realistic about the levels at which athletes should be participating. There are ways to make practices safer,” they wrote. “At [Wesleyan], we began the season in ‘cohorts,’ so the amount of people exposed to one another would be smaller. For non-contact sports, social distancing can be easily implemented, and for others, teams can focus on drills, strength and conditioning workouts, and skill-building exercises. Racing sports such as swim and track can compete virtually, comparing times with other schools, and team sports can focus their competition on intra-team scrimmages. These changes can allow for the continuation of a sense of normalcy and team camaraderie without the exposure to students from different geographic areas in confined, indoor spaces.”

Brook Guiffre ’23 and Maddie Clarke’s ’22  op-ed titled “ On the Pandemic ” was published in Hometown Weekly,  based in Medfield, Mass.

“The first case of COVID-19 in the United States was recorded on January 20th, 2020. For the next month and a half, the U.S. continued operating normally, while many other countries began their lockdown,” they wrote. “One month later, on February 29th, 2020, the federal government approved a national testing program, but it was too little too late. The U.S. was already in pandemic mode, and completely unprepared. Frontline workers lacked access to N-95 masks, infected patients struggled to get tested, and national leaders informed the public that COVID-19 was nothing more than the common flu. Ultimately, this unpreparedness led to thousands of avoidable deaths and long-term changes to daily life. With the risk of novel infectious diseases emerging in the future being high, it is imperative that the U.S. learn from its failure and better prepare for future pandemics now. By strengthening our public health response and re-establishing government organizations specialized in disease control, we have the ability to prevent more years spent masked and six feet apart.”

In addition, their other essay, “ On Mass Extinction ,” was also published by Hometown Weekly .

“The sixth mass extinction—which scientists have coined as the Holocene Extinction—is upon us. According to the United Nations, around one million plant and animal species are currently in danger of extinction, and many more within the next decade. While other extinctions have occurred in Earth’s history, none have occurred at such a rapid rate,” they wrote. “For the sake of both biodiversity and infectious diseases, it is in our best interest to stop pushing this Holocene Extinction further.”

An essay titled “ Learning from Our Mistakes: How to Protect Ourselves and Our Communities from Diseases ,” written by Nicole Veru ’21 and Zoe Darmon ’21, was published in My Hometown Bronxville, based in Bronxville, N.Y.

“We can protect ourselves and others from future infectious diseases by ensuring that we are vaccinated,” they wrote. “Vaccines have high levels of success if enough people get them. Due to vaccines, society is no longer ravaged by childhood diseases such as mumps, rubella, measles, and smallpox. We have been able to eradicate diseases through vaccines; smallpox, one of the world’s most consequential diseases, was eradicated from the world in the 1970s.

“In 2000, the U.S. was nearly free of measles, yet, due to hesitations by anti-vaxxers, there continues to be cases. From 2000–2015 there were over 18 measles outbreaks in the U.S. This is because unless a disease is completely eradicated, there will be a new generation susceptible.

“Although vaccines are not 100% effective at preventing infection, if we continue to get vaccinated, we protect ourselves and those around us. If enough people are vaccinated, societies can develop herd immunity. The amount of people vaccinated to obtain herd immunity depends on the disease, but if this fraction is obtained, the spread of disease is contained. Through herd immunity, we protect those who may not be able to get vaccinated, such as people who are immunocompromised and the tiny portion of people for whom the vaccine is not effective.”

Dhruvi Rana ’22 and Bryce Gillis ’22 co-authored an op-ed titled “ We Must Educate Those Who Remain Skeptical of the Dangers of COVID-19 ,” which was published in Rhode Island Central .

“As Rhode Island enters the winter season, temperatures are beginning to drop and many studies have demonstrated that colder weather and lower humidity are correlated with higher transmissibility of SARS-CoV-2, the virus that causes COVID-19,” they wrote. “By simply talking or breathing, we release respiratory droplets and aerosols (tiny fluid particles which could carry the coronavirus pathogen), which can remain in the air for minutes to hours.

“In order to establish herd immunity in the US, we must educate those who remain skeptical of the dangers of COVID-19.  Whether community-driven or state-funded, educational campaigns are needed to ensure that everyone fully comprehends how severe COVID-19 is and the significance of airborne transmission. While we await a vaccine, it is necessary now more than ever that we social distance, avoid crowds, and wear masks, given that colder temperatures will likely yield increased transmission of the virus.”

Danielle Rinaldi ’21 and Verónica Matos Socorro ’21 published their op-ed titled “ Community Forum: How Mask-Wearing Demands a Cultural Reset ” in the Ewing Observer , based in Lawrence, N.J.

“In their own attempt to change personal behavior during the pandemic, Wesleyan University has mandated mask-wearing in almost every facet of campus life,” they wrote. “As members of our community, we must recognize that mask-wearing is something we are all responsible and accountable for, not only because it is a form of protection for us, but just as important for others as well. However, it seems as though both Covid fatigue and complacency are dominating the mindsets of Americans, leading to even more unwillingness to mask up. Ultimately, it is inevitable that this pandemic will not be the last in our lifespan due to global warming creating irreversible losses in biodiversity. As a result, it is imperative that we adopt the norm of mask-wearing now and undergo a culture shift of the abandonment of an individualistic mindset, and instead, create a society that prioritizes taking care of others for the benefit of all.”

Shayna Dollinger ’22 and Hayley Lipson ’21  wrote an essay titled “ My Pandemic Year in College Has Brought Pride and Purpose. ” Dollinger submitted the piece, rewritten in first person, to Jewish News of Northern California . Read more about Dollinger’s publication in this News @ Wesleyan article .

“I lay in the dead grass, a 6-by-6-foot square all to myself. I cheer for my best friend, who is on the stage constructed at the bottom of Foss hill, dancing with her Bollywood dance group. Masks cover their ordinarily smiling faces as their bodies move in sync. Looking around at friends and classmates, each in their own 6-by-6 world, I feel an overwhelming sense of normalcy.

“One of the ways in which Wesleyan has prevented outbreaks on campus is by holding safe, socially distanced events that students want to attend. By giving us places to be and things to do on the weekends, we are discouraged from breaking rules and causing outbreaks at ‘super-spreader’ events.”

An op-ed written by Luna Mac-Williams ’22 and Daëlle Coriolan ’24 titled “ Collectivist Practices to Combat COVID-19 ” was published in the Wesleyan Argus .

“We are embroiled in a global pandemic that disproportionately affects poor communities of color, and in the midst of a higher cultural consciousness of systemic inequities,” they wrote. “A cultural shift to center collectivist thought and action not only would prove helpful in disease prevention, but also belongs in conversation with the Black Lives Matter movement. Collectivist models of thinking effectively target the needs of vulnerable populations including the sick, the disenfranchised, the systematically marginalized. Collectivist systems provide care, decentering the capitalist, individualist system, and focusing on how communities can work to be self-sufficient and uplift our own neighbors.”

An essay written by Maria Noto ’21 , titled “ U.S. Individualism Has Deadly Consequences ,” is published in the Oneonta Daily Star , based in Oneonta, N.Y.

She wrote, “When analyzing the cultures of certain East Asian countries, several differences stand out. For instance, when people are sick and during the cold and flu season, many East Asian cultures, including South Korea, use mask-wearing. What is considered a threat to freedom by some Americans is a preventive action and community obligation in this example. This, along with many other cultural differences, is insightful in understanding their ability to contain the virus.

“These differences are deeply seeded in the values of a culture. However, there is hope for the U.S. and other individualistic cultures in recognizing and adopting these community-centered approaches. Our mindset needs to be revolutionized with the help of federal and local assistance: mandating masks, passing another stimulus package, contact tracing, etc… However, these measures will be unsuccessful unless everyone participates for the good of a community.”

A published op-ed by Madison Szabo ’23 , Caitlyn Ferrante ’23 ran in the Two Rivers Times . The piece is titled “ Anxiety and Aspiration: Analyzing the Politicization of the Pandemic .”

John Lee ’21 and Taylor Goodman-Leong ’21 have published their op-ed titled “ Reassessing the media’s approach to COVID-19 ” in Weekly Monday Cafe 24 (Page 2).

An essay by Eleanor Raab ’21 and Elizabeth Nefferdorf ’22 titled “ Preventing the Next Epidemic ” was published in The Almanac .

How to Write About the Impact of the Coronavirus in a College Essay

The global impact of COVID-19, the disease caused by the novel coronavirus, means colleges and prospective students alike are in for an admissions cycle like no other. Both face unprecedented challenges and questions as they grapple with their respective futures amid the ongoing fallout of the pandemic.

Colleges must examine applicants without the aid of standardized test scores for many — a factor that prompted many schools to go test-optional for now . Even grades, a significant component of a college application, may be hard to interpret with some high schools adopting pass-fail classes last spring due to the pandemic. Major college admissions factors are suddenly skewed.

“I can’t help but think other (admissions) factors are going to matter more,” says Ethan Sawyer, founder of the College Essay Guy, a website that offers free and paid essay-writing resources.

College essays and letters of recommendation , Sawyer says, are likely to carry more weight than ever in this admissions cycle. And many essays will likely focus on how the pandemic shaped students’ lives throughout an often tumultuous 2020.

[ Read: How to Write a College Essay. ]

But before writing a college essay focused on the coronavirus, students should explore whether it’s the best topic for them.

Writing About COVID-19 for a College Application

Much of daily life has been colored by the coronavirus. Virtual learning is the norm at many colleges and high schools, many extracurriculars have vanished and social lives have stalled for students complying with measures to stop the spread of COVID-19.

“For some young people, the pandemic took away what they envisioned as their senior year,” says Robert Alexander, dean of admissions, financial aid and enrollment management at the University of Rochester in New York. “Maybe that’s a spot on a varsity athletic team or the lead role in the fall play. And it’s OK for them to mourn what should have been and what they feel like they lost, but more important is how are they making the most of the opportunities they do have?”

That question, Alexander says, is what colleges want answered if students choose to address COVID-19 in their college essay.

But the question of whether a student should write about the coronavirus is tricky. The answer depends largely on the student.

“In general, I don’t think students should write about COVID-19 in their main personal statement for their application,” Robin Miller, master college admissions counselor at IvyWise, a college counseling company, wrote in an email.

“Certainly, there may be exceptions to this based on a student’s individual experience, but since the personal essay is the main place in the application where the student can really allow their voice to be heard and share insight into who they are as an individual, there are likely many other topics they can choose to write about that are more distinctive and unique than COVID-19,” Miller says.

[ Read: What Colleges Look for: 6 Ways to Stand Out. ]

Opinions among admissions experts vary on whether to write about the likely popular topic of the pandemic.

“If your essay communicates something positive, unique, and compelling about you in an interesting and eloquent way, go for it,” Carolyn Pippen, principal college admissions counselor at IvyWise, wrote in an email. She adds that students shouldn’t be dissuaded from writing about a topic merely because it’s common, noting that “topics are bound to repeat, no matter how hard we try to avoid it.”

Above all, she urges honesty.

“If your experience within the context of the pandemic has been truly unique, then write about that experience, and the standing out will take care of itself,” Pippen says. “If your experience has been generally the same as most other students in your context, then trying to find a unique angle can easily cross the line into exploiting a tragedy, or at least appearing as though you have.”

But focusing entirely on the pandemic can limit a student to a single story and narrow who they are in an application, Sawyer says. “There are so many wonderful possibilities for what you can say about yourself outside of your experience within the pandemic.”

He notes that passions, strengths, career interests and personal identity are among the multitude of essay topic options available to applicants and encourages them to probe their values to help determine the topic that matters most to them — and write about it.

That doesn’t mean the pandemic experience has to be ignored if applicants feel the need to write about it.

Writing About Coronavirus in Main and Supplemental Essays

Students can choose to write a full-length college essay on the coronavirus or summarize their experience in a shorter form.

To help students explain how the pandemic affected them, The Common App has added an optional section to address this topic. Applicants have 250 words to describe their pandemic experience and the personal and academic impact of COVID-19.

[ Read: The Common App: Everything You Need to Know. ]

“That’s not a trick question, and there’s no right or wrong answer,” Alexander says. Colleges want to know, he adds, how students navigated the pandemic, how they prioritized their time, what responsibilities they took on and what they learned along the way.

If students can distill all of the above information into 250 words, there’s likely no need to write about it in a full-length college essay, experts say. And applicants whose lives were not heavily altered by the pandemic may even choose to skip the optional COVID-19 question.

“This space is best used to discuss hardship and/or significant challenges that the student and/or the student’s family experienced as a result of COVID-19 and how they have responded to those difficulties,” Miller notes. Using the section to acknowledge a lack of impact, she adds, “could be perceived as trite and lacking insight, despite the good intentions of the applicant.”

To guard against this lack of awareness, Sawyer encourages students to tap someone they trust to review their writing , whether it’s the 250-word Common App response or the full-length essay.

Experts tend to agree that the short-form approach to this as an essay topic works better, but there are exceptions. And if a student does have a coronavirus story that he or she feels must be told, Alexander encourages the writer to be authentic in the essay.

“My advice for an essay about COVID-19 is the same as my advice about an essay for any topic — and that is, don’t write what you think we want to read or hear,” Alexander says. “Write what really changed you and that story that now is yours and yours alone to tell.”

Sawyer urges students to ask themselves, “What’s the sentence that only I can write?” He also encourages students to remember that the pandemic is only a chapter of their lives and not the whole book.

Miller, who cautions against writing a full-length essay on the coronavirus, says that if students choose to do so they should have a conversation with their high school counselor about whether that’s the right move. And if students choose to proceed with COVID-19 as a topic, she says they need to be clear, detailed and insightful about what they learned and how they adapted along the way.

“Approaching the essay in this manner will provide important balance while demonstrating personal growth and vulnerability,” Miller says.

Pippen encourages students to remember that they are in an unprecedented time for college admissions.

“It is important to keep in mind with all of these (admission) factors that no colleges have ever had to consider them this way in the selection process, if at all,” Pippen says. “They have had very little time to calibrate their evaluations of different application components within their offices, let alone across institutions. This means that colleges will all be handling the admissions process a little bit differently, and their approaches may even evolve over the course of the admissions cycle.”

Discrete SARS-CoV-2 antibody titers track with functional humoral stability

The extent of antibody protection against SARS-CoV-2 remains unclear. Here, using a cohort of 120 seroconverted individuals, the authors longitudinally characterize neutralization, Fc-function, and SARS-CoV-2 specific T cell responses, which they show to be prominent only in those subjects that elicited receptor-binding domain (RBD)-specific antibody titers above a certain threshold, suggesting that development of T cell responses to be related to anti-RBD Ab production.

SARS-CoV-2-specific T cell memory is sustained in COVID-19 convalescent patients for 10 months with successful development of stem cell-like memory T cells

T cells are instrumental to protective immune responses against SARS-CoV-2, the pathogen responsible for the COVID-19 pandemic. Here the authors show that, in convalescent COVID-19 patients, memory T cell responses are detectable up to 317 days post-symptom onset, in which the presence of stem cell-like memory T cells further hints long-lasting immunity.

Seven-month kinetics of SARS-CoV-2 antibodies and role of pre-existing antibodies to human coronaviruses

Long-term characterisation of SARS-CoV-2 antibody kinetics is needed to understand the protective role of the immune response. Here the authors describe antibody levels and neutralisation activity in healthcare workers over seven months and investigate the role of immunity to endemic human coronaviruses.

Mechanism of SARS-CoV-2 polymerase stalling by remdesivir

Remdesivir is a nucleoside analog that inhibits the SARS-CoV-2 RNA dependent RNA polymerase (RdRp) and is used as a drug to treat COVID19 patients. Here, the authors provide insights into the mechanism of remdesivir-induced RdRp stalling by determining the cryo-EM structures of SARS-CoV-2 RdRp with bound RNA molecules that contain remdesivir at defined positions and observe that addition of the fourth nucleotide following remdesivir incorporation into the RNA product is impaired by a barrier to further RNA translocation.

This essay is part of “ Reimagining the global economy: Building back better in a post-COVID-19 world ,” a collection of 12 essays presenting new ideas to guide policies and shape debates in a post-COVID-19 world.

The COVID-19 pandemic has exposed the inadequacy of public health systems worldwide, casting a shadow that we could not have imagined even a year ago. As the fog of confusion lifts and we begin to understand the rudiments of how the virus behaves, the end of the pandemic is nowhere in sight. The number of cases and the deaths continue to rise. The latter breached the 1 million mark a few weeks ago and it looks likely now that, in terms of severity, this pandemic will surpass the Asian Flu of 1957-58 and the Hong Kong Flu of 1968-69.

Moreover, a parallel problem may well exceed the direct death toll from the virus. We are referring to the growing economic crises globally, and the prospect that these may hit emerging economies especially hard.

The economic fall-out is not entirely the direct outcome of the COVID-19 pandemic but a result of how we have responded to it—what measures governments took and how ordinary people, workers, and firms reacted to the crisis. The government activism to contain the virus that we saw this time exceeds that in previous such crises, which may have dampened the spread of the COVID-19 but has extracted a toll from the economy.

This essay takes stock of the policies adopted by governments in emerging economies, and what effect these governance strategies may have had, and then speculates about what the future is likely to look like and what we may do here on.

Nations that build walls to keep out goods, people and talent will get out-competed by other nations in the product market.

It is becoming clear that the scramble among several emerging economies to imitate and outdo European and North American countries was a mistake. We get a glimpse of this by considering two nations continents apart, the economies of which have been among the hardest hit in the world, namely, Peru and India. During the second quarter of 2020, Peru saw an annual growth of -30.2 percent and India -23.9 percent. From the global Q2 data that have emerged thus far, Peru and India are among the four slowest growing economies in the world. Along with U.K and Tunisia these are the only nations that lost more than 20 percent of their GDP. 1

COVID-19-related mortality statistics, and, in particular, the Crude Mortality Rate (CMR), however imperfect, are the most telling indicator of the comparative scale of the pandemic in different countries. At first glance, from the end of October 2020, Peru, with 1039 COVID-19 deaths per million population looks bad by any standard and much worse than India with 88. Peru’s CMR is currently among the highest reported globally.

However, both Peru and India need to be placed in regional perspective. For reasons that are likely to do with the history of past diseases, there are striking regional differences in the lethality of the virus (Figure 11.1). South America is worse hit than any other world region, and Asia and Africa seem to have got it relatively lightly, in contrast to Europe and America. The stark regional difference cries out for more epidemiological analysis. But even as we await that, these are differences that cannot be ignored.

To understand the effect of policy interventions, it is therefore important to look at how these countries fare within their own regions, which have had similar histories of illnesses and viruses (Figure 11.2). Both Peru and India do much worse than the neighbors with whom they largely share their social, economic, ecological and demographic features. Peru’s COVID-19 mortality rate per million population, or CMR, of 1039 is ahead of the second highest, Brazil at 749, and almost twice that of Argentina at 679.

Similarly, India at 88 compares well with Europe and the U.S., as does virtually all of Asia and Africa, but is doing much worse than its neighbors, with the second worst country in the region, Afghanistan, experiencing less than half the death rate of India.

The official Indian statement that up to 78,000 deaths 2 were averted by the lockdown has been criticized 3 for its assumptions. A more reasonable exercise is to estimate the excess deaths experienced by a country that breaks away from the pattern of its regional neighbors. So, for example, if India had experienced Afghanistan’s COVID-19 mortality rate, it would by now have had 54,112 deaths. And if it had the rate reported by Bangladesh, it would have had 49,950 deaths from COVID-19 today. In other words, more than half its current toll of some 122,099 COVID-19 deaths would have been avoided if it had experienced the same virus hit as its neighbors.

What might explain this outlier experience of COVID-19 CMRs and economic downslide in India and Peru? If the regional background conditions are broadly similar, one is left to ask if it is in fact the policy response that differed markedly and might account for these relatively poor outcomes.

Peru and India have performed poorly in terms of GDP growth rate in Q2 2020 among the countries displayed in Table 2, and given that both these countries are often treated as case studies of strong governance, this draws attention to the fact that there may be a dissonance between strong governance and good governance.

The turnaround for India has been especially surprising, given that until a few years ago it was among the three fastest growing economies in the world. The slowdown began in 2016, though the sharp downturn, sharper than virtually all other countries, occurred after the lockdown.

On the COVID-19 policy front, both India and Peru have become known for what the Oxford University’s COVID Policy Tracker 4 calls the “stringency” of the government’s response to the epidemic. At 8 pm on March 24, 2020, the Indian government announced, with four hours’ notice, a complete nationwide shutdown. Virtually all movement outside the perimeter of one’s home was officially sought to be brought to a standstill. Naturally, as described in several papers, such as that of Ray and Subramanian, 5 this meant that most economic life also came to a sudden standstill, which in turn meant that hundreds of millions of workers in the informal, as well as more marginally formal sectors, lost their livelihoods.

In addition, tens of millions of these workers, being migrant workers in places far-flung from their original homes, also lost their temporary homes and their savings with these lost livelihoods, so that the only safe space that beckoned them was their place of origin in small towns and villages often hundreds of miles away from their places of work.

After a few weeks of precarious living in their migrant destinations, they set off, on foot since trains and buses had been stopped, for these towns and villages, creating a “lockdown and scatter” that spread the virus from the city to the town and the town to the village. Indeed, “lockdown” is a bit of a misnomer for what happened in India, since over 20 million people did exactly the opposite of what one does in a lockdown. Thus India had a strange combination of lockdown some and scatter the rest, like in no other country. They spilled out and scattered in ways they would otherwise not do. It is not surprising that the infection, which was marginally present in rural areas (23 percent in April), now makes up some 54 percent of all cases in India. 6

In Peru too, the lockdown was sudden, nationwide, long drawn out and stringent. 7 Jobs were lost, financial aid was difficult to disburse, migrant workers were forced to return home, and the virus has now spread to all parts of the country with death rates from it surpassing almost every other part of the world.

As an aside, to think about ways of implementing lockdowns that are less stringent and geographically as well as functionally less total, an example from yet another continent is instructive. Ethiopia, with a COVID-19 death rate of 13 per million population seems to have bettered the already relatively low African rate of 31 in Table 1. 8

We hope that human beings will emerge from this crisis more aware of the problems of sustainability.

The way forward

We next move from the immediate crisis to the medium term. Where is the world headed and how should we deal with the new world? Arguably, that two sectors that will emerge larger and stronger in the post-pandemic world are: digital technology and outsourcing, and healthcare and pharmaceuticals.

The last 9 months of the pandemic have been a huge training ground for people in the use of digital technology—Zoom, WebEx, digital finance, and many others. This learning-by-doing exercise is likely to give a big boost to outsourcing, which has the potential to help countries like India, the Philippines, and South Africa.

Globalization may see a short-run retreat but, we believe, it will come back with a vengeance. Nations that build walls to keep out goods, people and talent will get out-competed by other nations in the product market. This realization will make most countries reverse their knee-jerk anti-globalization; and the ones that do not will cease to be important global players. Either way, globalization will be back on track and with a much greater amount of outsourcing.

To return, more critically this time, to our earlier aside on Ethiopia, its historical and contemporary record on tampering with internet connectivity 9 in an attempt to muzzle inter-ethnic tensions and political dissent will not serve it well in such a post-pandemic scenario. This is a useful reminder for all emerging market economies.

We hope that human beings will emerge from this crisis more aware of the problems of sustainability. This could divert some demand from luxury goods to better health, and what is best described as “creative consumption”: art, music, and culture. 10 The former will mean much larger healthcare and pharmaceutical sectors.

But to take advantage of these new opportunities, nations will need to navigate the current predicament so that they have a viable economy once the pandemic passes. Thus it is important to be able to control the pandemic while keeping the economy open. There is some emerging literature 11 on this, but much more is needed. This is a governance challenge of a kind rarely faced, because the pandemic has disrupted normal markets and there is need, at least in the short run, for governments to step in to fill the caveat.

Emerging economies will have to devise novel governance strategies for doing this double duty of tamping down on new infections without strident controls on economic behavior and without blindly imitating Europe and America.

Here is an example. One interesting opportunity amidst this chaos is to tap into the “resource” of those who have already had COVID-19 and are immune, even if only in the short-term—we still have no definitive evidence on the length of acquired immunity. These people can be offered a high salary to work in sectors that require physical interaction with others. This will help keep supply chains unbroken. Normally, the market would have on its own caused such a salary increase but in this case, the main benefit of marshaling this labor force is on the aggregate economy and GDP and therefore is a classic case of positive externality, which the free market does not adequately reward. It is more a challenge of governance. As with most economic policy, this will need careful research and design before being implemented. We have to be aware that a policy like this will come with its risk of bribery and corruption. There is also the moral hazard challenge of poor people choosing to get COVID-19 in order to qualify for these special jobs. Safeguards will be needed against these risks. But we believe that any government that succeeds in implementing an intelligently-designed intervention to draw on this huge, under-utilized resource can have a big, positive impact on the economy 12 .

This is just one idea. We must innovate in different ways to survive the crisis and then have the ability to navigate the new world that will emerge, hopefully in the not too distant future.

S7-Episode 2: Bringing Health to the World

“You see, we're not doing this work to make ourselves feel better. That sort of conventional notion of what a do-gooder is. We're doing this work because we are totally convinced that it's not necessary in today's wealthy world for so many people to be experiencing discomfort, for so many people to be experiencing hardship, for so many people to have their lives and their livelihoods imperiled.”

Dr. David Nabarro has dedicated his life to global health. After a long career that’s taken him from the horrors of war torn Iraq, to the devastating aftermath of the Indian Ocean tsunami, he is still spurred to action by the tremendous inequalities in global access to medical care.

“The thing that keeps me awake most at night is the rampant inequities in our world…We see an awful lot of needless suffering.”

Essay on COVID-19 Pandemic

As a result of the COVID-19 (Coronavirus) outbreak, daily life has been negatively affected, impacting the worldwide economy. Thousands of individuals have been sickened or died as a result of the outbreak of this disease. When you have the flu or a viral infection, the most common symptoms include fever, cold, coughing up bone fragments, and difficulty breathing, which may progress to pneumonia. It’s important to take major steps like keeping a strict cleaning routine, keeping social distance, and wearing masks, among other things. This virus’s geographic spread is accelerating (Daniel Pg 93). Governments restricted public meetings during the start of the pandemic to prevent the disease from spreading and breaking the exponential distribution curve. In order to avoid the damage caused by this extremely contagious disease, several countries quarantined their citizens. However, this scenario had drastically altered with the discovery of the vaccinations. The research aims to investigate the effect of the Covid-19 epidemic and its impact on the population’s well-being.

There is growing interest in the relationship between social determinants of health and health outcomes. Still, many health care providers and academics have been hesitant to recognize racism as a contributing factor to racial health disparities. Only a few research have examined the health effects of institutional racism, with the majority focusing on interpersonal racial and ethnic prejudice Ciotti et al., Pg 370. The latter comprises historically and culturally connected institutions that are interconnected. Prejudice is being practiced in a variety of contexts as a result of the COVID-19 outbreak. In some ways, the outbreak has exposed pre-existing bias and inequity.

Thousands of businesses are in danger of failure. Around 2.3 billion of the world’s 3.3 billion employees are out of work. These workers are especially susceptible since they lack access to social security and adequate health care, and they’ve also given up ownership of productive assets, which makes them highly vulnerable. Many individuals lose their employment as a result of lockdowns, leaving them unable to support their families. People strapped for cash are often forced to reduce their caloric intake while also eating less nutritiously (Fraser et al, Pg 3). The epidemic has had an impact on the whole food chain, revealing vulnerabilities that were previously hidden. Border closures, trade restrictions, and confinement measures have limited farmer access to markets, while agricultural workers have not gathered crops. As a result, the local and global food supply chain has been disrupted, and people now have less access to healthy foods. As a consequence of the epidemic, many individuals have lost their employment, and millions more are now in danger. When breadwinners lose their jobs, become sick, or die, the food and nutrition of millions of people are endangered. Particularly severely hit are the world’s poorest small farmers and indigenous peoples.

Infectious illness outbreaks and epidemics have become worldwide threats due to globalization, urbanization, and environmental change. In developed countries like Europe and North America, surveillance and health systems monitor and manage the spread of infectious illnesses in real-time. Both low- and high-income countries need to improve their public health capacities (Omer et al., Pg 1767). These improvements should be financed using a mix of national and foreign donor money. In order to speed up research and reaction for new illnesses with pandemic potential, a global collaborative effort including governments and commercial companies has been proposed. When working on a vaccine-like COVID-19, cooperation is critical.

The epidemic has had an impact on the whole food chain, revealing vulnerabilities that were previously hidden. Border closures, trade restrictions, and confinement measures have limited farmer access to markets, while agricultural workers have been unable to gather crops. As a result, the local and global food supply chain has been disrupted, and people now have less access to healthy foods (Daniel et al.,Pg 95) . As a consequence of the epidemic, many individuals have lost their employment, and millions more are now in danger. When breadwinners lose their jobs, the food and nutrition of millions of people are endangered. Particularly severely hit are the world’s poorest small farmers and indigenous peoples.

While helping to feed the world’s population, millions of paid and unpaid agricultural laborers suffer from high levels of poverty, hunger, and bad health, as well as a lack of safety and labor safeguards, as well as other kinds of abuse at work. Poor people, who have no recourse to social assistance, must work longer and harder, sometimes in hazardous occupations, endangering their families in the process (Daniel Pg 96). When faced with a lack of income, people may turn to hazardous financial activities, including asset liquidation, predatory lending, or child labor, to make ends meet. Because of the dangers they encounter while traveling, working, and living abroad; migrant agricultural laborers are especially vulnerable. They also have a difficult time taking advantage of government assistance programs.

The pandemic also has a significant impact on education. Although many educational institutions across the globe have already made the switch to online learning, the extent to which technology is utilized to improve the quality of distance or online learning varies. This level is dependent on several variables, including the different parties engaged in the execution of this learning format and the incorporation of technology into educational institutions before the time of school closure caused by the COVID-19 pandemic. For many years, researchers from all around the globe have worked to determine what variables contribute to effective technology integration in the classroom Ciotti et al., Pg 371. The amount of technology usage and the quality of learning when moving from a classroom to a distant or online format are presumed to be influenced by the same set of variables. Findings from previous research, which sought to determine what affects educational systems ability to integrate technology into teaching, suggest understanding how teachers, students, and technology interact positively in order to achieve positive results in the integration of teaching technology (Honey et al., 2000). Teachers’ views on teaching may affect the chances of successfully incorporating technology into the classroom and making it a part of the learning process.

In conclusion, indeed, Covid 19 pandemic have affected the well being of the people in a significant manner. The economy operation across the globe have been destabilized as most of the people have been rendered jobless while the job operation has been stopped. As most of the people have been rendered jobless the living conditions of the people have also been significantly affected. Besides, the education sector has also been affected as most of the learning institutions prefer the use of online learning which is not effective as compared to the traditional method. With the invention of the vaccines, most of the developed countries have been noted to stabilize slowly, while the developing countries have not been able to vaccinate most of its citizens. However, despite the challenge caused by the pandemic, organizations have been able to adapt the new mode of online trading to be promoted.

Coronavirus (SARS-CoV-2), the cause of COVID-19, a fatal disease emerged from Wuhan, a large city in the Chinese province of Hubei in December 2019.

Main body of abstract

The World Health Organization declared COVID-19 as a pandemic due to its spread to other countries inside and outside Asia. Initial confirmation of the pandemic shows patient exposure to the Huanan seafood market. Bats might be a significant host for the spread of coronaviruses via an unknown intermediate host. The human-to-human transfer has become a significant concern due to one of the significant reasons that is asymptomatic carriers or silent spreaders. No data is obtained regarding prophylactic treatment for COVID-19, although many clinical trials are underway.

The most effective weapon is prevention and precaution to avoid the spread of the pandemic. In this current review, we outline pathogenesis, diagnosis, treatment, ongoing clinical trials, prevention, and precautions. We have also highlighted the impact of pandemic worldwide and challenges that can help to overcome the fatal disease in the future.

Coronaviruses (CoVs) are a large family of RNA viruses; they show discrete point-like projections over their surface. They show the presence of an unusually large RNA genome and a distinctive replication strategy. The term “coronavirus” is acquired from the “crown”-like morphology. Coronaviruses show potential fatal human respiratory infections and cause a variety of diseases in animals and birds [ 1 ]. Coronavirus primarily targets the human respiratory system [ 2 ]. The World Health Organization (WHO) named the latest virus as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on 12 January 2020 [ 3 ]. The COVID-19 or the SARS-CoV-2 is rapidly unfurling from Wuhan in Hubei Province of China to worldwide [ 4 ].

Initial confirmation of the pandemic was carried out by conducting studies on 99 patients with COVID-19 pneumonia, from which 49% of patients exhibited a history of subjection to the Huanan seafood market. The patient examined had a clinical manifestation of fever, cough, shortness of breath, muscle ache, and sore throat-like symptoms [ 5 ]. COVID-19 has infected several hundreds of humans and has caused many fatal cases [ 6 ]. Worldwide, there have been 3,925,815 confirmed cases, including 274,488 deaths of COVID-19 as of 6:37 pm CEST 10 May 2020 reported to WHO [ 7 ].

This article outlines and gives a complete overview of SARS-CoV-2, including its pathogenesis, diagnosis, treatment, prevention, and precautions. This article also provides the current scenario of the pandemic worldwide, since new findings are rapidly evolving and can help the readers in upgrading their knowledge about the COVID-19. It also emphasizes the challenges faced by giving an idea about future strategies in fighting and preventing recurrence.

History and origin

Coronaviruses were not expected to be highly infectious to humans, but the outburst of a severe acute respiratory syndrome (SARS) in Guangdong province China in the years 2002 and 2003 proved to be devastating. SARS-CoV is the contributory agent of the SARS, also known as “atypical pneumonia”. The coronaviruses that spread before that time in humans mostly caused mild infections in immune-competent people. But after the emergence of SARS, another highly infectious coronavirus, MERS-CoV, appeared in Middle Eastern countries [ 8 , 9 ]. Research has shown that SARS-CoV-2 shows similarities with SARS-CoV and MERS-CoV. (Table ​ (Table1) 1 ) depicts a comparison of SARS-CoV-2 with SARS-CoV and MERS-CoV [ 10 – 16 ]. Several disseminating strains of coronaviruses were identified and were considered harmless pathogens, causing common cold and mild upper respiratory illness [ 17 ]. HCoV-229E [ 18 ] strain was isolated in 1966. HCoV-NL63 was first isolated from the Netherlands during late 2004. In 2012, MERS-CoV was first identified from the lung of a 60-year-old patient who was suffering from acute pneumonia and renal failure in Saudi Arabia [ 19 ]. About 8000 cases and 800 deaths worldwide were observed due to the outbreak of SARS first human pandemic in the dawn of the twenty-first century [ 20 ].

Comparison of coronaviruses

Note: despite the lower case fatality rate observed in COVID-19, the overall number of death far outweighs that from SARS and MERS

The α-CoVs HCoV-229E and HCoV-NL63 and β-CoVs HCoV-HKU1 and HCoV-OC43 are identified as a human susceptible virus with low pathogenicity and cause mild respiratory symptoms similar to common cold [ 21 ]. SARS-CoV and MERS-CoV result in severe respiratory tract infections [ 22 , 23 ]. COVID-19 was recently reported from Wuhan (China), which has cases in Thailand, Japan, South Korea, and the USA, which has been confirmed as a new coronavirus [ 24 ].

The coronavirus genera, which mostly infect mammals, are alpha-coronavirus and beta-coronavirus. Out of 15 presently assigned viral species, seven were isolated from bats. The research proposed that bats are significant hosts for alpha-coronaviruses and beta-coronaviruses and play an essential role as the gene source in the evolution of these two coronavirus genera SARS and MERS [ 25 ]. The genome sequence was found to be 96.2% identical to a bat CoV RaTG13, whereas it shares 79.5% identity to SARS-CoV. The virus genome sequencing outcomes and evolutionary analysis show that bat can be a natural host from virus source, and SARS-CoV-2 might be transferred from bats through unspecified intermediate hosts to infect humans [ 26 ]. It is found that SARS-CoV-2 affects males more than females [ 27 ]. The spread of SARS-CoV-2 emerged like a wild forest fire in many countries worldwide. Table ( ​ (2) 2 ) [ 28 ] gives a brief of the first identified cases of COVID-19 in different countries.

First confirmed case

The first confirmed case was reported in China, and since then, there was a widespread of coronavirus in other countries worldwide. Table ​ Table1 1 shows the first confirmed case with dates

Coronaviruses are spherical to pleomorphic enveloped particles [ 29 ]. The size ranges from 80 to 120 nm in diameter. The maximum size is as small as 50 nm and as large as 200 nm are also seen [ 30 ]. There are four types of main structural proteins observed in the coronaviruses: the spike (S), membrane (M), envelope (E), and nucleocapsid (N) proteins, which are encoded within the viral genome (Table ​ (Table3). 3 ). In thin sections, the virion envelope may be visualized as inner and outer shells separated by a translucent space [ 31 ]. The virion envelope contains phospholipids, glycolipids, cholesterol, di- and triglycerides, and free fatty acids in proportions. The complexed genome RNA is with the basic nucleocapsid (N) protein, which forms a helical capsid established within the viral membrane. The enclosed glycoproteins are responsible for attachment to the host cells [ 32 ].

Structural proteins of coronavirus and their functions

According to the recent studies, it is observed that coronavirus which lacks envelope protein (E) serves as a good candidate in vaccine designing

The coronavirus genomes are among the most massive mature RNA molecules as compared to other eukaryotic RNAs (Fig. ​ (Fig.1) 1 ) [ 33 ]. The genome of these viruses contains multiple ORFS. A typical CoV consists of at least 6 ORFs in its genome. Several studies have confirmed the genetic resemblance between SARS-CoV-2 and a bat CoV.

Structure of novel coronavirus

A study conducted to compare the genetic mutations of COVID showed genomic mutations among viruses from different countries, wherein a sequence obtained from Nepal showed minimum to no variations. In contrast, the maximum number of modifications was obtained from one derived from the Indian series located in ORF1-ab nsp2 nsp3 helicase ORF8 and spike surface glycoprotein. Also, host antiviral mRNAs play a critical part in the regulation of immune response to virus infection, depending upon the viral agent. The unique host mRNAs could be explored in the development of novel antiviral therapies. The club-like surface projections or peplomers of coronaviruses are about 17–20 nm from the virion surface. It has a subtle base that swells to a width of about 10 nm at the distal extremity. Some coronaviruses that exhibit the second set of projections about 5–10-nm long are present beneath the significant projections. These shorter spikes are now known as hemagglutinin-esterase (HE) protein, an additional membrane protein found in a subset of group 2 coronaviruses. The primary role of this non-essential protein is to aid in viral entry and pathogenesis in vivo. It configures short projections that bind to N-acetyl-9-O-acetlyneuramic acid or N-glycolylneuraminic acid and have esterase [ 34 – 39 ]. Figure ​ Figure2 2 shows the primary classification of coronavirus.

Classification of coronavirus

Lifecycle of coronavirus

The life cycle of the virus with the host consists of the following four steps: attachment, penetration, biosynthesis, maturation, and release (Fig. ​ (Fig.3). 3 ). Once the virus binds to the host receptor, they enter host cells through endocytosis or membrane fusion. Once the viral contents are released inside the host cells, viral RNA enters the nucleus for replication. Viral mRNA is used to make viral proteins and is further proceeded by maturation and release [ 40 , 41 ].

Attachment and entry

The virion attachment with the host cell is initiated by interaction between S protein and its receptors, which is also a primary determinant for coronavirus infection. The S protein undergoes acid-dependent proteolytic cleavage, which results in exposure of fusion peptide. This fusion is followed by the formation of a six-helix bundle (bundle formation helps in combining viral and cellular membrane) and release of the viral genome into the cytoplasm.

Replicase protein expression

The process of translation of replicase gene ORFs1a and ORFs1b and translation of polyprotein pp1a and pp1ab takes place. Assembly of nsps into replicase-transcriptase complex (RTC) leads to viral RNA synthesis (replication and transcription of subgenomic RNAs).

Replication and transcription

In the replication process, the viral RNA synthesis is followed by the production of genomic and sub-genomic RNAs (sub-genomic mRNAs), which further leads to recombination of the virus.

Assembly and release

The insertion and translation of viral structure protein S, E, and M takes place into the endoplasmic reticulum (ER), which is followed by the movement of proteins along the secretory pathway into ERGIC (endoplasmic reticulum Golgi intermediate compartment). The viral genome is encapsidated by N protein into the membrane of ERGIC. M and E protein expression give rise to the formation of virus-like particles (VLPs). After the assembly of the virion and its transportation to cell surface vesicles, exocytosis takes place. Finally, it results in viral release (E protein helps by altering the host secretory pathway).

The incubation period is the period between the entry of the virus into the host and appearance of signs and symptoms in the host or the period between the earliest date of contact of the transmission source and the most initial time of symptom onset (i.e., cough, fever, fatigue, or myalgia) [ 42 ]. The incubation period of COVID-19 is vital as the disease could be transmitted during this phase through asymptomatic as well as symptomatic carriers (Table ​ (Table4). 4 ). The inhaled virus SARS-CoV-2 binds to the epithelial cells present in the nasal cavity and starts replicating.

Incubation period of coronaviruses

On the basis of studies conducted and data findings, virologists points out that incubation period extends to 14 days, with a median time of 4–5 days from exposure to symptom onset. One study reported that 97.5% of persons with COVID-19 who develop symptoms will do so within 11.5 days of SARS-CoV-2 infection

ACE2 is the primary receptor for both SARS-CoV-2 and SARS-CoV, which is an asymptomatic state (initial 1–2 days of infection). Upper airway and conducting airway response are seen the next few days. The disease is mild and mostly restricted only to the upper conducting airways for about 80% of the infected patients [ 43 ].

The incubation period is required to create more productive quarantine systems for people infected with the virus. The incubation period for the COVID-19 is between 2 and 14 days after exposure. A newly infected person shows symptoms in the about 5 days after contact with a sick patient. In most patients, symptoms appeared after 12–14 days of infection

The average incubation period was approximated to be 5.1 days, and 97.5% of those who develop symptoms will do so within 11.5 days of infection. In Wuhan’s return patients, the average incubation period is found to be 6.4 days. In a case reported by Hubei province, local government on 22 February showed an incubation period of 27 days. In another case, an incubation period of 19 days was observed. Therefore a 24-day observation period is considered in suspected cases by the Chinese government and also by WHO [ 44 – 51 ]. The frequency of cases is increasing day by day, and it is essential to keep a check over it. Figure ​ Figure4 4 gives a glance of confirmed cases cumulative and death overtime cumulative from 10 January onwards up to 25 May.

Pathogenesis

Like other CoVs, the SARS-CoV-2 is transmitted primarily via respiratory droplets and possible faeco-oral transmission routes [ 52 ]. Figure ​ Figure5 5 gives a complete outline of the pathogenesis of coronavirus. On infection, primary viral replication is expected to occur in the mucosal epithelium of the upper respiratory tract with further multiplication into the lower respiratory tract and GI mucosa, giving rise to mild viremia. The virus enters the host cells through two methods either:

• I. Direct entry
• II. Endocytosis

Complete pathogenesis of coronavirus

These are positive sense ss-RNA viruses that can cause respiratory, enteric, hepatic, and neurologic diseases. High binding capacity with SARS-CoV-2 was observed by molecular biological analysis [ 53 ]. The ACE2 gene encodes the angiotensin-converting enzyme-2 receptor for both the SARS-CoV and the human respiratory coronavirus NL63. Recent studies show that ACE2 could be the host receptor for the novel coronavirus 2019-nCoV/SARS-CoV-2 [ 54 ].

Human angiotensin-converting enzyme 2 (hACE2), which was the binding receptor of SARS-CoV, is analogous to SARS-CoV-2. These hACE2 are type 1 membrane proteins expressed in various cells of the nasal mucosa, lung, bronchus, heart, kidney, intestines, bladder, stomach, esophagus, and ileum. It functions as an enzyme in the RAS and is, therefore, mainly associated with cardiovascular diseases [ 55 ].

The zinc peptidase ACE2 has also expressed in the alveolar type 2 pneumocytes, which explains its role in lung damage due to SARS-CoV. The SARS-CoV-2 shows 10–12-fold more affinity towards the proteins than the other SARS-CoV. Pathophysiology and virulence of the virus link to the function of its nsps and structural proteins. The nsp can block the host’s innate mechanism response while the virus envelope increases the pathogenicity as it assists the assembly and release of the virus [ 56 ].

The CoV spike glycoproteins comprise of three segments—a large ectodomain, a single-pass transmembrane anchor, and a small intracellular tail. The ectodomain is composed of the receptor-binding domain (RBD)—the S1 and the membrane fusion subunit S2. The two significant areas in s1, N-terminal domain (NTD) and the c-terminal domain (CTD), have been identified. The S1 NTDs are essential for binding to the sugar receptors, and the s1 CTDs are responsible for binding receptors ACE2, SPN, and DPP4 [ 57 ]. The S proteins undergo a considerable structural rearrangement to fuse with the viral membrane of the host cell membrane. The s1 subunit shedding and the s2 subunit transition to a highly stable conformation is the initial step in the fusion process [ 58 ]. The ACE2 consists of the N-terminal peptidase domain (NPD) and the C-terminal collectrin-like domain (CCTD) that ends with a single transmembrane helix and a 40 residue intracellular segment. It provides a direct binding site for S protein of CoVs.

The enzymes which assist this virus attachment include the serine protease enzymes TMPRSS2. These enzymes, which are cell-surface proteases, facilitate entry. In endosomes, the S1 of s proteins is cleaved, and the fusion peptides S2 are exposed. This exposed S2 unit brings the HR1 and HR2 together, resulting in membrane fusion and thereby release of viral package into the host membrane [ 59 ].

The viral RNA enters the nucleus for replication after the viral contents are released. Viral mRNA is used to make viral proteins. Decreased expression of ACE2 in a host cell results in an attack on the airway epithelium by the virus. These lead to acute lung injury that triggers immune responses. The release of various pro-inflammatory and chemokines like IL-6, IFN- gamma, MCPI 1, and IL-10 leads to capillary permeability in alveolar sacs. Due to local inflammation in the lungs, the secretion of pro-inflammatory cytokines and chemokines increases into the blood circulation of the patient. It results in fluid filling and increased difficulty in the exchange of gases across the membrane. Viral replication and infection in airway epithelial cells could cause high levels of virus-linked pyroptosis with associated vascular leakage. IL-beta cytokine released during pyroptosis is a highly inflammatory form of programmed cell death, which is the trigger subsequent inflammatory response. The IgG antibodies against SARS-CoV-2 N protein can be detected in the serum in the early stages at the onset of the disease. The non-neutralizing antibodies result in ADE (antibody-dependent enhancement), which leads to an increased systematic inflammatory response.

The pro-inflammatory cytokines and chemokines are an indicator of T H cells. Secretions from such cytokines and chemokines attract immune cell monocytes and T lymphocytes. High levels of pro-inflammatory cytokines, including IL-2, IL-7, IL-10, IP-10, G-CSF, MCP-1, MIP-1A, and TNF alpha, were detected in the severe infection called cytokine storm or cytokine release syndrome as a crucial factor in the pathogenesis of COVID-19.

The cytokine storm increases the inflammatory response resulting in increased blood plasma levels of neutrophils IL-6, IL-10, granulocytes, MCP1, TNF, and decreased organ perfusion, which results in multiple organ failure. Cytokine storm and pulmonary edema due to ACE2 dysregulation result in acute respiratory distress syndrome. SARS-CoV-2 can also affect the CNS [ 60 ]. Myocardial damage increases the difficulty and complexity of patient treatment [ 61 ]. Clinical investigations have shown that patients with cardiac diseases, hypertension, or diabetes, who are treated with ACE2-increasing drugs, including inhibitors and blockers, are at higher risk of getting infected with SARS-CoV2 [ 62 ]. Death results due to ARDS and multiple organ failure.

People with COVID-19 infection show symptoms ranging from mild to severe illness. Figure ​ Figure6 6 shows a brief outline of various symptoms related to COVID-19. The warning signs and symptoms such as trouble breathing, constant pain or pressure in the chest, inability to wake or stay awake, and bluish lips or face are observed in patients [ 63 ]. Older people (65 years and older) are at higher risk of developing the disease.

Symptoms for coronavirus

According to a study, people of all ages having asthma, diabetes, HIV, liver diseases, severe heart conditions, severe obesity (body mass index [BMI] of 40 or higher), and chronic kidney diseases undergoing dialysis show a higher mortality rate. The other populations with people showing disabilities, pregnancy, and breastfeeding and people experiencing homelessness, racial, and minority groups are at elevated risk of transmission of disease [ 64 ]. The crucial fact to know about coronavirus on surfaces is that they can easily be cleaned with ordinary household disinfectants that will kill the virus [ 65 ]. Studies have shown (Fig. ​ (Fig.7) 7 ) that the COVID-19 virus can survive for up to 72 h on plastic and stainless steel, about 4 h on copper, and less than 24 h on cardboard [ 66 ].

Survival of virus on various objects

Diagnosis: COVID-19

There are two categories of tests available for COVID-19:

• Viral tests: a viral analysis indicates whether a person has a current infection.
• Antibody tests: an antibody indicates whether a person had an infection.

The protection of getting infected again in a person showing the presence of antibodies to the virus is still unexplained [ 67 ].

Tests for current infection

A swab sample is collected (from the nose) to conclude that a person is currently infected with SARS-CoV-2. Some tests are called as point-of-care tests, which means their results may be available in less than an hour. Other test takes 1–2 days for analyzing after being received by the laboratory [ 68 ].

Test for past infection

Antibody tests analyze a blood sample for the presence of antibodies, which show if one had a previous infection with the virus. Antibody tests cannot be used to diagnose someone as being currently infected with COVID-19. Antibody tests are accessible through healthcare providers and laboratories [ 69 ]. In severe cases, clinical diagnosis is done based on the clinical manifestations of respiratory failure syndrome, increased liver function tests, blood tests indicating leukopenia, and high levels of ferritin. For such, a test for soluble CD-163 (sCD-163), showing the activation of macrophages, was suggested [ 70 ]. Laboratory diagnosis included genomic sequencing, reverse-transcription polymerase chain reaction (RT-PCR), and serological methods (such as enzyme-linked immunoassay [ELISA]). Because of the rapidly changing diversity found in the expression of the novel coronavirus, pneumonia became diverse and quickly changed. Other methods used are radiographic images for early observations and evaluation of disease severity [ 71 ].

Reverse-transcription polymerase chain reaction (RT-PCR) shows high sensitivity for new SARS cases. The suspected cases must be confirmed by using RT-PCR and other methods (slower methods) of detection such as serology or viral culture, isolation, and identification by electron microscopy, thereby causing a significant increase in the time required for an accurate diagnosis [ 72 ]. The samples are collected from upper and lower respiratory tracts through expectorated sputum, bronchoalveolar lavage, or endotracheal aspirate, which are then assessed by conducting polymerase chain reaction for viral RNA. It is recommended to repeat the test for reevaluation purposes in case of a positive result, and if the test is negative, a strong clinical impression also permits repeat testing [ 73 ].

An alternative diagnostic test to detect the SARS-CoV is mass spectroscopic identification of microbial nucleic acid signatures. Computed tomography images of the lungs showed 100% multiple patchy with fine mesh and consolidated shade distributed under the pleura. Nucleic acid tests were conducted in 187 patients, and all were positive to SARS-CoV-2. In the pulmonary CT images, 8% of them (15 cases) showed diffused lesions in either lungs or white lung. In the absorptive period, 98.9% showed fibrogenesis and diminished lesions. The CT imaging features differed from each follow-up showing different clinical symptoms [ 74 ]. The improvement in the detection of COVID-19 was found by the ELISA method. It is based on SARS r-CoV Rp3 nucleocapsid protein, which helps to detect the IgM and IgG against SARS-CoV-2. ELISA is a highly recommended method as the sampling blood is less stringent, and antibodies allow longer windows than oropharyngeal swabs for detecting viruses [ 75 ].

There is no particular treatment recommended for COVID-19. There is no data obtained regarding prophylactic treatment for COVID-19, only we can prevent from coming in contact with the pathogen. Confirmed cases are hospitalized and admitted in the same ward. Patients with mild symptoms may not require hospitalization [ 76 ]. They are isolated or self-isolated at home by following the doctor’s advice. Critically ill patients (respiratory shock, respiratory failure, septic shock, or other organ failures) should be admitted to ICU as soon as possible [ 77 ].

General treatment

The general treatment includes bed rest and supportive measures ensuring sufficient intake of calories, fluid, and electrolytes, and maintenance of acid-base homeostasis. Monitoring oxygen saturation and vital signs, keeping the respiratory tract unobstructed and inhaling oxygen, measuring C-reactive protein, hematology and biochemistry laboratory testing and ECG, blood gas analysis, and examining of chest images as when required and monitoring for any complications [ 78 ]. Patients having high body temperature above 38.5°C Celsius are administered with ibuprofen and acetaminophen orally.

Oxygen therapy

Patients with conditions of obstructed breathing, respiratory distress, shock, coma, and convulsions must receive oxygen therapy and airway management, targeting SpO2 more significant than 94%. Initiate O 2 treatment at 5 L/min and titrated to reach the target or use a face mask with a reservoir bag (10–15 L/min) if the patients are in critical condition.

Once stable, the target is 90% SpO2 in non-pregnant adults and 95% in pregnant adults. The use of nasal prongs or nasal cannula is preferred in young children, as they may be better tolerated. When oxygen therapy fails, mechanical ventilation is necessary. In a meta-analysis, the use of additional oxygen therapy (38.9%), non-invasive (7.1%) and invasive ventilation (28.7%), and even ECMO (0.9%) was surprisingly high among the 1876 patients in which any kind of pharmacological and supportive intervention was reported [ 79 ].

Antiviral agents

Remdesivir inhibits virus infection at the micromolar level (0.77–1.13 μM) and with high selectivity [ 80 ]. Remdesivir gets incorporated into viral RNA due to its adenosine analog nature and results in premature chain termination [ 81 ]. Remdesivir is not approved by the Food and Drug Administration (FDA). It is only recommended for mild or moderate COVID-19 conditions and the treatment of hospitalized adults and children in emergencies.

Chloroquine/hydroxychloroquine

Chloroquine increases endosomal pH, making the environment unfavorable for viral cell fusion. It also affects the glycosylation process of ACE-2. On administering chloroquine after 1 h of infection, gradual loss of antiviral activity was seen, though it affects the endosome fusion when administered shortly after the infection. When administered after 3–5 h after the infection, chloroquine was significantly effective against HCoV strain OC43 [ 82 ]. There is an excessive risk of toxicities due to high chloroquine doses; the recommended dose for chloroquine is 600 mg twice daily for 10 days for the treatment of COVID-19.

Interferon–alpha

Interferon-α is used in treating bronchiolitis; viral pneumonia; acute upper respiratory tract infection; hand, foot, and mouth disease; SARS; and other viral infections in children. According to the clinical research and experiences, the following usage is recommended for COVID-19

• Interferon-α nebulization: interferon-α 200,000–400,000 IU/kg or 2–4 μg/kg in 2 mL sterile water, nebulization two times per day for 5–7 days
• Interferon-α2b spray: applied for high-risk populations with close contact with suspected COVID-19 infected patients or those in the early phase with only upper respiratory tract symptoms.

Lopinavir/ritonavir

In a clinical trial among adult patients of or less than 18 years, it was observed that a combination of lopinavir/ritonavir, ribavirin, and interferon beta-1b would speed up the recovery, suppress the viral load, shorten hospitalization, and reduce mortality compared with lopinavir/ritonavir [ 83 ].

Immune-based therapy

Patients who show an inadequate response to initial therapy can get benefit from immunoglobulin [ 84 ]. Non-SARS-CoV-2-specific IVIG should not be used for COVID-19 except in case of clinical trials.

Corticosteroids

Corticosteroids are widely used in the symptomatic treatment of severe pneumonia. According to a detailed review and analysis, the result indicates that patients with severe conditions required corticosteroid therapy [ 85 ]. According to a systematic review of literature, daily use of corticosteroids in a COVID-19 patient is not encouraged; however, some studies suggest that methylprednisolone can reduce the mortality rate in more severe conditions, such as in ARDS [ 86 ].

Antimicrobial therapy

Patients with a mild type of bacterial infection can take oral antibiotics, such as cephalosporin or fluoroquinolones. Although a patient may be a suspect for COVID-19, appropriate antimicrobial agent should be administered within an hour of recognition of sepsis. Antibiotic therapy should be based on the clinical diagnosis of community-acquired pneumonia, healthcare-associated pneumonia, local epidemiology, susceptibility data, and national treatment guidelines. When there is the ongoing local circulation of seasonal influenza, this therapy with a neuraminidase inhibitor should be considered for the treatment for patients [ 87 ].

Tocilizumab

According to a review, 25 patients with laboratory-confirmed severe COVID-19 who received tocilizumab and completed 14 days of follow-up, 36% were discharged alive from the intensive care unit, and 12% died [ 88 ]. The biopsy specimen analysis suggested that increased alveolar exudates resulted from an immune response against an inflammatory cytokine storm. Probably an obstruction in alveolar gas exchange contributed to the high mortality rate of severe COVID-19 patients. A study identified that pathogenic T cells and inflammatory monocytes arouse an inflammatory storm with a large amount of interleukin 6. Tocilizumab blocks IL-6 receptors, which shows encouraging clinical results, including controlling temperature quickly and improved respiratory functions. Henceforth, tocilizumab is useful in the treatment of severe COVID-19 patients to calm the inflammatory storm and reduce mortality [ 89 ].

FDA-approved drug ivermectin for parasitic infection has a possibility for reprocessing and acts as an inhibitor of SARS-CoV-2 in vitro. A single therapy can affect approximately 500-fold reduction and effectual loss of substantially all viral material by 48 h [ 90 ]. A single of ivermectin, in combination with doxycycline, yielded the near-miraculous result in curing the patients with COVID-19 virtually.

Azithromycin

Azithromycin is used for patients with viral pneumonia from COVID-19. It can also work synergistically and coactively with other antiviral treatments. It has also shown antiviral activity against the Zika virus and rhinoviruses, which cause the common cold. Viral infection was significantly reduced in patients receiving hydroxychloroquine than those who did not. The virus elimination was efficient in patients who received both azithromycin and hydroxychloroquine [ 91 ]. (Table ​ (Table5) 5 ) lists other supporting agents used in treatment [ 92 ].

Supporting agents used in treatment

The repurposing of available therapeutic drugs is being used as supporting agents in the treatment of COVID-19; however, the efficacy of these treatments should be verified by using designed clinical trials

Precautions and preventions

WHO declared the COVID-19 outbreak as a public health emergency of international concern on 30 January 2020. Unfortunately, no medication until now is approved by the FDA, and various trials are going on. Still, the most effective weapon the community has in hand is the prevention of spread. The following are some of the COVID-19 prevention measures.

• Quarantine: self-quarantine, mandatory quarantine (private residence, hospital, public institution, etc.)
• Other measures: avoiding crowding, hand hygiene, isolation, personal protective equipment, school/workplace measures/closures, social distancing [ 93 ].

Asymptomatic carriers as the “silent spreaders” are of great concern for the elimination of disease and its control. So, more attention should be given to them [ 94 ]. Hand hygiene with alcohol-based hand-rub is globally recommended as productive and economical procedures against SARS-CoV-2 cross-transmission [ 95 ]. The economic implications of hand hygiene have been established. It has been found that this cost under 1% of total HAI-related economics. It is better to invest not only in the materials needed but also in the people working there. This investment will lead to an increase in the health outcome [ 96 ]. The clinical presentation of COVID-19 is non-specific, so it needs a robust and accurate diagnosis. It has been suggested that before stopping the infection control measures, we have to be sure to exclude the diagnosis [ 97 ]. Prevention plays a vital role in treating and defeating the COVID-19 disaster.

The Centers for Disease Control and Prevention gives standard precautions (Fig. ​ (Fig.8) 8 ) and recommends measures to prevent COVID-19. Wear personnel protective equipment (face shield, mask, gown, gloves, and closed-toed shoes) when evaluating persons at risk. N-95 masks are known to prevent up to 95% of small particles, including viruses [ 98 ]. Cover all coughs/sneezes with a tissue and then throw the tissue away. Regularly clean/disinfect frequently touched objects and surfaces with household cleaning spray and use a tissue when handling (e.g., doorknobs, sink taps, water fountain handles, elevator buttons, cross-walk buttons, and shopping carts). Avoid contact with infected people (recommended > 6 ft) and maintain an appropriate distance as much as possible and refrain from touching nose eyes and mouth [ 99 ]. Avoid well persons when you are ill. Wear a mask continuously if taking care of persons with respiratory illness. To turn on the tap, use a paper towel and then wash hands with soap and water for at least 30 s after going to the bathroom. Use hand sanitizer and carry whenever at a public venue. Activate community-based interventions (e.g., cancel sporting events, dismiss, termination of universities and schools, practice social distancing, create employee plans to work remotely) [ 100 ]. Create a household-ready plan. Cancel any non-essential travel [ 101 ]. Frequent disinfection and cleaning are advised for groups that are at risk of contracting the virus [ 102 ].

Prevention and precaution

In an Indian study mathematical approach was used to address some questions related to intervention strategies to control the COVID-19 transmission in India. Some hypothetical epidemic curves helped to illustrate the critical findings [ 103 ]. Predication of spread and implications of prevention and control using the Maximum-Hasting (MH) parameter assessment method and the modified Susceptible Exposed Infectious Recovered (SEIR) model was done. Suppression, mitigation, and mildness were the three predicted outlines for the spread of infection in some African countries [ 104 ].

Infection control strategies that can be acquired in hospitals were accomplished in a Taiwanese hospital to tackle the COVID-19 pandemic. These included emergency vigilance and responses from the hospital administration, education, surveillance, patient flow arrangement, the partition of hospital zones, and the prevention of a systemic shutdown by using the “divided cabin, divided flow” strategy. These measures may not be universally appropriate [ 105 ]. The preventive measures implemented in China included countrywide health education campaigns. The Examine and Approve Policy on the continuation of work, working and living quarters, a health Quick Response code system, community screening, and social distancing policies were some of the preventive measures [ 106 ].

Based on the analysis of immigration population data, the Epidemic Risk Time Series Model was outlined to estimate the effectiveness of COVID-19 epidemic control and prevention among different regions in China. Compared to other methods, this model was able to issue early recognition more instantaneously. For the prevention and control of COVID-19, this model can be generalized and applied to other countries [ 107 ]. The majority of clinical trials involving COVID-19 vaccines or treatment are showing encouraging results. (Tables ​ (Tables6 6 and ​ and7) 7 ) show ongoing phase 3 and 4 clinical trials [ 108 ].

Impact of COVID-19 on overall health of the people worldwide

The international response to COVID-19 has been more transparent and efficient when compared to the SARS outbreak [ 109 ].

The pandemic COVID-19, being a most severe strainer, is affecting the overall health system worldwide. There is a continuously increasing demand for healthcare facilities and associated workers, which is overstretching the ability to operate efficiently [ 110 ]. Some pieces of evidence are showing a destructive effect on maternal and child health. Some financial, educational, sanitation, and even clinical constraints are threatening the overall population of the children [ 111 ]. As coronavirus is sweeping across the world, the primary psychological impact is elevated in terms of stress and anxiety. The quarantine period is expected to raise cases involving suicidal behavior, substance abuse, self-harm, depression, and loneliness. WHO Department of Mental Health and Substance use has given some messages to overcome psychological impacts [ 112 ]. There is a relationship between human development and infectious diseases. Whichever changes (new technology, constructions of dams, deforestations, migration, increasing populations, the emergence of urban ghettoes, globalization of food, and increasing international travel) brought about by the development, are stretching the word into the mouth of such pandemics indirectly. This pandemic is having a significant impact on the global economy as the erosion of capacity and rise in poverty [ 113 , 114 ].

COVID-19 has affected the population differently based on gender. Significantly, this crisis is affecting the reproductive and sexual health of women. Another point is that there should be an equal contribution to both the genders in any healthcare body. There should be more distribution of decision-making power among them [ 115 ]. Protective measures can effectively prevent COVID-19 infection, including improving personal hygiene, wearing N95 masks, adequate rest, and proper ventilation [ 116 ].

Have to learn to live with COVID-19

The Health Ministry has said that we have to learn to survive with COVID-19. We cannot step ahead by carrying the burden of COVID-19 that could recur annually and kill so many people [ 117 ]. Governments are learning to strike a balance between controlling COVID-19 spread and allowing individual freedoms and economic activity. Measures such as lockdowns, arbitrary travel bans, widespread quarantines, intrusive screening of people crossing boundaries can be adopted for prevention. Virtual work will become much more common. Supplier close-downs, sudden employee truancy, and demand collapse caused by disease outbreaks will make the businesses able to withstand disruptions.

The government, industry, or specialist certification for disease control processes and standards similar to ISO 9001 or USFDA certificate will be a crucial part of many businesses. The cost of traveling will expand more due to the risk of infection and lockdown. At the same time, the responsibility of work airlines, hotels, and restaurants will be added to minimize infection risk. Delivery businesses will perform well, and “Contactless delivery” is already a thing.

The industries that provide products to help circumvent, control, diminish, or treat COVID-19 will flourish. The requirement for hospital rooms will increase tremendously, with an increasing need for reserves of equipment, supplies, and drugs. In the upcoming time, businesses are likely to face demand crisis as the world comes to terms with living in a state of medical beleaguerment [ 118 ]. It is just a prediction, but we can still aspire for the best [ 119 ]. The most destructive effects would be in countries with weak health systems, on-going disputes, or existing infectious disease epidemics.

In contrast, the health systems in high-income countries would be stretched out by the outbreak [ 120 ]. It has been seen that resources are limited in countries with poor scientific infrastructure, such as Nepal, where there was only one laboratory equipped to test for coronavirus infection. Fear and stigma is an evident feature of the COVID-19; it has affected the economic and social development of many countries worldwide [ 121 ].

The insufficiency of the trained workforce capable of performing experiments required to test for SARS-CoV-2 and interpret the results is another major limitation in the testing and confinement of COVID-19 in developing countries [ 122 ]. The virus has the potential to adapt and get through the different environmental conditions, which makes it quite difficult to identify its mode of survival [ 123 ]. Another crucial impediment in a research project is a suitable model to investigate in vivo mechanism associated with the pathogenesis of SARS-CoV-2 [ 124 – 126 ].

Current screening approaches for COVID-19 are likely to miss approximately 50% of the infected cases, even in countries with sound health systems and available diagnostic capacities. Many symptoms correlated with COVID-19 are similar to malaria, such as fever, difficulty in breathing, fatigue, and headaches of acute onset. If symptoms alone are used to specify a case during the emergency period then, a malaria case may be misinterpreted as COVID-19. The symptoms for malaria are seen within 10–15 days after an infective bite; multi-organ failure is common in severe cases among adults, while respiratory distress is also expected in children [ 127 ].

COVID-19 has emerged as the most terrified and enormous viral infection. According to WHO, the coronavirus might become an endemic disease. Originating from China as a global pandemic, it has influenced people on a large scale. There is no clear end that can be seen for this contagious disease. The only possible cure for this pandemic is prevention. We have to face it as a global community and support each other. The amplification of positivity will have a tremendous impact on the whole society. It is the duty of each individual for self-supervision and to report COVID-19 status, and challenging for those who appear to be ill. The other measure which can be followed to tackle this pandemic is healthy nourishment, sanitation, and hygiene practices robust connection and communication among children, and counseling to face the situation. Special care should be given to older people and pregnant ladies. It is better to get information only from the trusted sources; it is vital to get the facts and not the misinformation or rumors. Healthcare servants should have excellent and accurate communication with the public and must provide emotional and practical support. The ongoing pandemic of COVID-19 has caused not only notable morbidity and mortality in the world but also revealed significant systematic problems in the control and prevention of infectious diseases.

2 Minute Speech on Covid-19 (CoronaVirus) for Students

The year, 2019, saw the discovery of a previously unknown coronavirus illness, Covid-19 . The Coronavirus has affected the way we go about our everyday lives. This pandemic has devastated millions of people, either unwell or passed away due to the sickness. The most common symptoms of this viral illness include a high temperature, a cough, bone pain, and difficulties with the respiratory system. In addition to these symptoms, patients infected with the coronavirus may also feel weariness, a sore throat, muscular discomfort, and a loss of taste or smell.

10 Lines Speech on Covid-19 for Students

The Coronavirus is a member of a family of viruses that may infect their hosts exceptionally quickly.

Humans created the Coronavirus in the city of Wuhan in China, where it first appeared.

The first confirmed case of the Coronavirus was found in India in January in the year 2020.

Protecting ourselves against the coronavirus is essential by covering our mouths and noses when we cough or sneeze to prevent the infection from spreading.

We must constantly wash our hands with antibacterial soap and face masks to protect ourselves.

To ensure our safety, the government has ordered the whole nation's closure to halt the virus's spread.

The Coronavirus forced all our classes to be taken online, as schools and institutions were shut down.

Due to the coronavirus, everyone was instructed to stay indoors throughout the lockdown.

During this period, I spent a lot of time playing games with family members.

Even though the cases of COVID-19 are a lot less now, we should still take precautions.

Short 2-Minute Speech on Covid 19 for Students

The coronavirus, also known as Covid - 19 , causes a severe illness. Those who are exposed to it become sick in their lungs. A brand-new virus is having a devastating effect throughout the globe. It's being passed from person to person via social interaction.

The first instance of Covid - 19 was discovered in December 2019 in Wuhan, China . The World Health Organization proclaimed the covid - 19 pandemic in March 2020. It has now reached every country in the globe. Droplets produced by an infected person's cough or sneeze might infect those nearby.

The severity of Covid-19 symptoms varies widely. Symptoms aren't always present. The typical symptoms are high temperatures, a dry cough, and difficulty breathing. Covid - 19 individuals also exhibit other symptoms such as weakness, a sore throat, muscular soreness, and a diminished sense of smell and taste.

Vaccination has been produced by many countries but the effectiveness of them is different for every individual. The only treatment then is to avoid contracting in the first place. We can accomplish that by following these protocols—

Put on a mask to hide your face. Use soap and hand sanitiser often to keep germs at bay.

Keep a distance of 5 to 6 feet at all times.

Never put your fingers in your mouth or nose.

Long 2-Minute Speech on Covid 19 for Students

As students, it's important for us to understand the gravity of the situation regarding the Covid-19 pandemic and the impact it has on our communities and the world at large. In this speech, I will discuss the real-world examples of the effects of the pandemic and its impact on various aspects of our lives.

Impact on Economy | The Covid-19 pandemic has had a significant impact on the global economy. We have seen how businesses have been forced to close their doors, leading to widespread job loss and economic hardship. Many individuals and families have been struggling to make ends meet, and this has led to a rise in poverty and inequality.

Impact on Healthcare Systems | The pandemic has also put a strain on healthcare systems around the world. Hospitals have been overwhelmed with patients, and healthcare workers have been stretched to their limits. This has highlighted the importance of investing in healthcare systems and ensuring that they are prepared for future crises.

Impact on Education | The pandemic has also affected the education system, with schools and universities being closed around the world. This has led to a shift towards online learning and the use of technology to continue education remotely. However, it has also highlighted the digital divide, with many students from low-income backgrounds facing difficulties in accessing online learning.

Impact on Mental Health | The pandemic has not only affected our physical health but also our mental health. We have seen how the isolation and uncertainty caused by the pandemic have led to an increase in stress, anxiety, and depression. It's important that we take care of our mental health and support each other during this difficult time.

Real-life Story of a Student

John is a high school student who was determined to succeed despite the struggles brought on by the Covid-19 pandemic.

John's school closed down in the early days of the pandemic, and he quickly found himself struggling to adjust to online learning. Without the structure and support of in-person classes, John found it difficult to stay focused and motivated. He also faced challenges at home, as his parents were both essential workers and were often not available to help him with his schoolwork.

Despite these struggles, John refused to let the pandemic defeat him. He made a schedule for himself, to stay on top of his assignments and set goals for himself. He also reached out to his teachers for additional support, and they were more than happy to help.

John also found ways to stay connected with his classmates and friends, even though they were physically apart. They formed a study group and would meet regularly over Zoom to discuss their assignments and provide each other with support.

Thanks to his hard work and determination, John was able to maintain good grades and even improved in some subjects. He graduated high school on time, and was even accepted into his first-choice college.

John's story is a testament to the resilience and determination of students everywhere. Despite the challenges brought on by the pandemic, he was able to succeed and achieve his goals. He shows us that with hard work, determination, and support, we can overcome even the toughest of obstacles.

BRIEF RESEARCH REPORT article

Sharing lessons learned from covid-19 vaccine introductions: a global community forum for countries.

• 1 Department of Immunization, Vaccines, and Biologicals, World Health Organization, Geneva, Switzerland
• 2 Department of Health Security Preparedness, World Health Organization, Geneva, Switzerland
• 3 ECHO Institute, University of New Mexico, Albuquerque, NM, United States

To optimize the efficient introduction and deployment of COVID-19 vaccines across the globe during the COVID-19 pandemic, in April 2021 WHO launched a new process and tools for countries to rapidly review the early phase of countries’ COVID-19 vaccine introduction. This methodology is called the COVID-19 vaccination intra-action review, also known as mini COVID-19 vaccine post-introduction evaluation (mini-cPIE). As of November 2022, 46 mini-cPIEs had been conducted. In collaboration with Project ECHO, WHO convened and facilitated real-time experience sharing and peer-learning among countries following their mini-cPIEs through a virtual global real-time learning forum. This five-session clinic series was attended by 736 participants from 129 countries. Based on post-session feedback surveys, when asked about the utility of the sessions, half of the participants said that sessions led them to review national guidelines and protocols or make other changes to their health systems. The post-series survey sent following the end of the clinic series showed that at least eight countries subsequently conducted a mini-cPIE after participating in the clinics, and participants from at least nine countries indicated the experience shared by peer countries on the clinic largely benefited their COVID-19 vaccine introduction and deployment. In this article, we highlight the benefits and importance of creating a global experience-sharing forum for countries to connect and share pertinent learnings in real-time during an international public health emergency. Moving forward, it is critical to foster a culture of individual and collective learning within and between countries during public health emergencies, with WHO playing an important convening role.

Introduction

The World Health Organization (WHO) recommends that countries conduct a post-introduction evaluation (PIE) 6–12 months following the introduction of a new vaccine ( 1 ) to help countries evaluate implementation and take corrective actions. A PIE aims to fully assess the progress of vaccine introduction and can be time and resource-intensive requiring in-person field visits at all levels of the immunization system ( 2 , 3 ). The COVID-19 pandemic, however, necessitated the rapid vaccination of the entire global population ( 4 ). Countries had little time to conduct a full programme evaluation such as a PIE, especially during the early phases of COVID-19 vaccine introduction and deployment ( 5 ).

To address this need, WHO developed a new evaluation method by adapting the WHO COVID-19 intra-action review (IAR) for countries to conduct a simpler, shorter and more flexible version of the PIE process, coined as mini-cPIE ( 6 – 8 ). The mini-cPIE was developed in line with the National Deployment and Vaccination Plan for COVID-19 vaccines (NDVP) ( 9 ), COVID-19 vaccine post-introduction evaluation (cPIE) and COVID-19 Strategic Preparedness and Response Plan (SPRP) ( 10 ). The WHO guidance for conducting a COVID-19 IAR ( 11 ) was developed soon after the pandemic onset for key stakeholders to collectively identify practices and lessons learned to course-correct and improve the ongoing response ( 12 ). During the IAR, a facilitator guides group discussions, in-person or virtual, over a period of 2–3 days using trigger questions pre-selected to address country needs. Based on the findings, the stakeholders then collectively recommend short-and mid-to long-term follow-up activities.

As countries and partners began using the mini-cPIE, they were eager to learn about ongoing vaccination implementation challenges and emerging best practices to improve their own processes and coverage. With this goal in mind, WHO collaborated with Project ECHO (Extension for Community Healthcare Outcomes) to create a global virtual community of practice (vCoP) called the mini-cPIE clinic, consisting of virtual learning sessions for countries to share and learn from experiences in real-time with immunization peers. These were referred to as “clinics” henceforth. During clinics, countries that had recently conducted a mini-cPIE were invited to present their learnings and best practices to peers that were planning or considering conducting a mini-cPIE. This was followed by Q&A/discussion that allowed for direct connection between countries.

Five clinic sessions were conducted from July to December 2021 ( 13 ). Clinic design was informed both by a past WHO-ECHO vCOP series on broader COVID-19 immunization, and by Project ECHO’s 20 years of experience implementing the ECHO collaborative-learning model. This model supports low-dose, high-frequency, virtual case-based learning to promote timely peer-to-peer information sharing and collaborative problem solving. This learning approach has proved to be instrumental in improving health outcomes during COVID-19, in other public health emergency responses and as related to general continuing health professional education ( 14 – 19 ).

The objectives of the clinics were threefold: (1) to create a forum for countries having conducted a mini-cPIE to share their experiences and learnings with stakeholders and peer countries; (2) to cultivate a community of learning and collaborative problem solving for COVID-19 vaccine introduction; and (3) to provide opportunities for countries interested in conducting a mini-cPIE to receive practical tips and technical guidance. The intended audience of the clinics were country immunization representatives interested in conducting, planning to conduct, or who had conducted a mini-cPIE, as well as partners technically or financially supporting these activities.

In this article, we describe the clinic design and participants’ characteristics, challenges, lessons, and best practices shared by presenting countries, and the perceived value of the clinics among participants.

Clinic design, content, and promotion

Between July and December 2021, WHO hosted a series of monthly, 90-min clinics on the Zoom videoconferencing platform. Clinics began with two to three country presentations followed by facilitated discussion, presentations from experts on immunization topics of interest, questions and answers, and interactive polls for real-time feedback from participants. The clinics were designed to be interactive, with participating countries able to directly engage with and ask questions to presenting countries. All questions that were not addressed during the clinic due to time constraints were compiled and shared with all participants and posted on the TechNet-21 immunization community collaboration platform ( 13 ). To maximize accessibility and promote multilingualism, simultaneous interpretation was provided to and from English, French, Spanish, Russian, Arabic and Portuguese. To further encourage participant engagement, a Telegram instant messaging group was established to offer participants an additional opportunity to continue discussions and experience sharing asynchronously outside the clinics.

Over the course of the six-month series, the Ministries of Health of 10 countries from four WHO regions, the African (AFR), American (AMR), Eastern Mediterranean (EMR) and South-East Asia (SEAR) regions, accepted the invitation to virtually present on their experiences with recently conducted mini-cPIEs ( Table 1 ). The first two clinics addressed the conduct of and general learnings from mini-cPIEs -- including successes, challenges, and lessons learned -- and covered all immunization programme areas defined in the COVID-19 National Deployment Vaccination Plan (NDVP). The format of the clinics evolved through the series based on participant feedback and immunization topics that arose during that period of the pandemic. For the final three clinics, the presenting countries were asked to focus on specific immunization programme themes pertinent to challenges observed during the COVID-19 vaccine introduction and deployment ( Table 1 ).

Table 1 . Overview of the virtual mini-cPIE clinic series hosted by WHO and ECHO project, July–December 2021.

Advocacy and outreach efforts were made to ensure the intended target audiences were aware of scheduled clinic sessions. These included engaging with WHO regional and country focal points for both immunization and health emergencies so that they would share information about upcoming clinics with relevant country-level counterparts. Participants were also invited to join the sessions relevant to their interests through email announcements, social media, and Project ECHO and TechNet-21 platforms. Pre-registration was required for attendance and open to the public. After each session, Project ECHO distributed session materials (i.e., recordings, presentations, and Q&A responses) along with announcements for the subsequent session. Session materials were also posted on the TechNet-21 collaboration platform.

Data collection and analysis

Participant demographic data were collected upon registration via a unique Zoom link, including name, email, gender, area(s) of expertise, professional affiliation, geographic level (e.g., multi-country, national, sub-national), and country. Registration and attendance data from Zoom reports were linked by email address. The first session registration data did not include gender, area(s) of expertise, and region of work. That and a few incomplete responses explain discrepancies in the result’s profile data totals.

A link to an anonymous online post-session survey ( Supplementary Appendix 1 ) was shared with all participants for the third, fourth and fifth clinics, with digital certificates of participation provided to participants who completed the survey. The survey asked participants about their knowledge of the session’s topic before and after; relevance of the session to their current work; balance of lecture and interactivity; and intention to use what was learned in their work. In addition, Project ECHO distributed a post-series survey via email in November 2022 (eleven months after the last session) to all program participants to solicit feedback about the entire clinic series, including qualitative examples of barriers to conducting mini-cPIEs and improvements to vaccine roll-out linked to series learnings ( Supplementary Appendix 2 ). The University of New Mexico Health Sciences Institutional Review Board approved the evaluation (ID 20–469).

Chi-square and Fisher’s exact tests were used to compare results across dichotomized geography (multi-country versus single-country) and country income levels. The Wilcoxon signed-rank test was used to compare knowledge before and after sessions. Quantitative analyses were conducted in R version 2022.07.1. Open-ended text responses were coded systematically using NVivo 1.4.1.

Characteristics of participants

From 28 July 2021 until 14 December 2021, 996 attendances were recorded over five clinics. Among these, 736 unique individuals from 129 countries across all six WHO regions participated in at least one clinic session ( Table 2 and Supplementary Figure S1 ). The number of participants in each session ranged widely from 88 to 241. Most ( n = 563; 76.5%) participants attended only one session and 23.5% ( n = 173) attended two or more. More participants ( n = 436; 59.6%) described themselves as working in a single country versus multiple countries ( n = 296; 40.4%) (i.e., working at the regional or global level). More than half (59.2%) of participants were in low or lower-middle income countries. The most common areas of expertise among attendees were immunization ( n = 244; 37.7%) followed by emergency preparedness ( n = 149; 23.0%) and program management ( n = 146; 22.5%) ( Table 2 ). Participants attended an average of 1.4 clinics each. Participants representing a single country were less likely to attend multiple sessions than those working at the regional or global level ( Table 2 ).

Lessons learned and best practices shared by countries

Country case studies were presented by either government representatives or WHO immunization experts from Bhutan, The Plurinational State of Bolivia, Democratic Republic of Congo (DRC), Gambia, Ghana, Mozambique, Senegal, South Sudan, Somalia, and Uganda. Speakers shared the importance of strong political commitment to mobilize national resources, bilateral negotiations for donations to increase access to vaccines, and multi-sector engagement to mobilize human resources. Strong inter-sectoral collaboration contributed to successes in every thematic area. Leading by example, political and community leaders were able to build trust and improve vaccine uptake.

Immunization experts from countries highlighted their successes with key innovations. Bhutan described how the Prime Minister boosted public confidence by receiving the first and second doses of a heterologous regimen. Bhutan achieved 95% vaccine coverage for the first dose and more than 90% vaccine coverage for the second dose following the first national vaccination campaigns. The Gambia described using a “vaccine caravan” to improve vaccine uptake and engage remote communities. Ghana used an innovative yet cost-effective approach for authentication of vaccination status with metallic holograms on vaccination cards, as well as utilizing drones to deliver vaccines to hard-to-reach areas.

Challenges and proposed solutions were shared together, although sometimes these solutions highlighted additional difficulties. For example, Senegal successfully established a COVID-19 Adverse Event Following Immunization (AEFI) committee and investigated all serious AEFIs; however, with this success came the challenge of how the country was addressing the lack of free medical care for those experiencing serious AEFIs. Uganda addressed delays in deployment of funds to the operational level by emphasizing early and transparent communication with health workers to instill confidence and allow continued vaccination services during resolution of administrative problems. Somalia described challenges in the availability and distribution of doses due to short expiry dates and described forecasting tools used to improve vaccine management and distribution. Bolivia worked to address coverage disparities through review of uptake data disaggregated by geographic area, target population, age, and gender. In low uptake populations, Bolivia prioritized single-dose regimens to minimize the risk of drop-out and reduce vaccine access inequity.

Strong risk communication and social listening activities at subnational and local levels were described by several Ministries of Health as essential to successful COVID-19 vaccine deployment. South Sudan dispelled rumors by acting on behavior survey findings through media engagement, high-level advocacy meetings, radio programmes and jingles, especially when new variants of concern emerged and created a loss of public confidence in COVID-19 vaccines. In the session focusing on unique risk communication and community engagement approaches, the DRC described strategies to build confidence among high-risk populations through strong interpersonal communication of health workers, pre-registration and monitoring of vaccination status to allow health worker follow-up and engagement. Mozambique used multiple communication channels to create public demand for vaccines and regularly monitored and managed rumors through a technical working group and digital platform.

Poll responses

During the clinics, polls gathered real-time feedback from attendees. Examples of polling questions used were, “What topics/themes related to COVID-19 vaccine roll-out would you like to see discussed in future mini-cPIE clinics?” and “In a few words, what risk communication and community engagement strategies have you seen that worked well to increase COVID-19 vaccine uptake?.” The polls, whose answers were visible to all, were successful in enabling quick sharing of perspectives from multiple country or partner representatives from the audience and stimulated further discussion on new topics ( Supplementary Figure S2 ).

Post-clinic feedback surveys

The response rate for post-session surveys was 11.0% ( n = 117). In post-session surveys, respondents rated their post-session knowledge significantly higher than before the session ( Supplementary Figure S3 ) ( p  < 0.001). Almost all survey respondents ( n = 110; 94.0%) reported the “right” balance of didactic and interactive learning. Additionally, most ( n = 110; 94.0%) would definitely or probably recommend the session to a colleague and 80.2% reported the session was extremely or very relevant to their work. Most respondents would “definitely” ( n = 94; 80.3%) or “probably” ( n = 17; 14.5%) use information from the session in their respective work. The most common way participants planned to use the information was to share with colleagues ( n = 81; 69.2%) followed by general use ( n = 73; 62.4%), looking up additional information ( n = 63; 53.8%), and making guidelines, protocols, or other changes to health systems ( n = 60; 51.3%). Almost one-third ( n = 37; 31.6%) planned to change how they worked with patients or community members.

Qualitative comments from post-session surveys reinforced the quantitative findings ( Table 3 ). Respondents found the knowledge and information shared in each session useful and noted plans to share with colleagues or stakeholders as well as using them to develop communication strategies for advocacy or community outreach. One respondent reported, “ I liked the ideas of evidence-based communication, analysis of community feedback to craft communication products that respond to community inquiries , etc.” while another said, “ The information shared in the session increased my understanding of challenges in other contexts which also apply to the African region .” Answers from respondents helped inform priority COVID-19 topics for future sessions, including vaccines, booster dose policies, vaccine misinformation and hesitancy, financing, and metrics. Respondents also appreciated peer-sharing: “ It was a great cross learning opportunity. The challenges [encountered] in [fragile, conflict-affected, and vulnerable] settings are similar but the way these are addressed is the key learning .”

Post-series survey

The response rate for the post-series survey was 5.4% ( n = 40) ( Table 4 ). Most respondents primarily worked in a single country characterized as low or low-middle income ( n = 19; 63.3%). Fifteen respondents (37.5%) from eight countries mentioned that their countries began planning or conducting a mini-cPIE due to their participation in the clinic series. For 66.7% of those respondents ( n = 10), participation in the series significantly helped inform planning, implementation, and follow-up. Planning or implementation of a mini-cPIE was more likely to be reported by low income or lower-middle income country respondents compared to high income or upper-middle income countries ( p  < 0.01; Supplementary Figure S4 ).

Table 4 . Characteristics of post-series survey respondents and reported impact of the virtual mini-cPIE clinic series hosted by WHO and ECHO project, November 2022.

Nearly three quarters of respondents (72.5%, n = 29) affirmed that their participation in the clinic series had improved their countries’ COVID-19 vaccine introduction and deployment a lot or some amount ( Table 4 ). The improvements shared by the respondents varied but referred to specific strategies learned during the clinics. For example, “ More vaccination posts were created to support community access and decongest health facilities. In addition, vaccination campaigns to de-stigmatize vaccines were held across the country physically and through media .” Additionally, respondents mentioned adjustments to their national vaccination plans, new strategies for prioritization of high-risk populations, strengthening vaccination data management, and long-term integration of COVID-19 vaccination efforts within the national immunization and health system. Seven respondents shared barriers to using learnings from the series including immunization decision-making being outside their scope of work or scheduling conflicts to participate in more sessions.

WHO, recognizing the importance and urgency of real-time peer-learning, leveraged its global coordinating role to rapidly convene countries and partners in the clinics described in this article. WHO, in collaboration with Project ECHO, created a global virtual learning forum for countries to highlight and share with peer countries their respective challenges, solutions, and innovations experienced during their COVID-19 vaccine introduction and deployment. While Project ECHO had prior experience establishing virtual communities of practice related to clinical medicine topics ( 16 – 18 ), this method for real-time peer-to-peer virtual learning was first used for the global immunization community during the pandemic. At the start of the COVID-19 pandemic prior to the mini-cPIE clinic series, WHO and Project ECHO collaborated on the ACT Accelerator COVID-19 initiatives ( 19 ), and a second series that convened partners and practitioners to build global capacity in preparation for COVID-19 vaccination ( 14 ). Several studies have shown that virtual training can help equip healthcare professionals with knowledge and skills for effective vaccination deployment during critical times of the COVID-19 pandemic ( 20 , 21 ). The mini-cPIE clinic series was novel as it not only showcased the use of the intra-action review process recommended by the International Health Regulations Emergency Committee ( 22 ) early in the pandemic, but it also leveraged the virtual multi-country platform for case-based learning including country-level case presentations and participation from national public health practitioners.

Use of a virtual platform was essential given pandemic restrictions on in-person convening but also greatly reduced costs for convening large audiences. The establishment of the virtual platform also enabled WHO to continually advocate on behalf of Member States for additional technical and financial support from partners and donors. Participants who responded to post-session surveys found the clinics valuable. Survey responses show the value of clinics for participants in several ways, including a self-reported significant increase in knowledge, a high likelihood of endorsing the clinics, and plans to use the newly acquired knowledge. Evidence from the post-series survey reinforces this value, particularly for low and middle-income countries, by supporting the planning or conducting a mini-cPIE. Perceived value is also reflected in the suggestions for improvement, including requests for more sessions, more topics, and more time for discussion and interaction. The fact that most attendees attended only one and not multiple sessions suggests that either attendees were interested in a specific country presentation or a vaccination topic, or they were busy and could only select specific sessions to attend. Some participants may have taken advantage of the option to watch recordings of the sessions in addition to attending live.

Participant feedback was used to adapt clinic content to be most relevant and useful. For example, one of the clinics was dedicated to COVID-19 vaccine introduction and deployment in Fragile States/humanitarian contexts ( 13 ). The importance of strong risk communication strategies and community engagement was mentioned in multiple clinics, and given common challenges in this area, participants also expressed interest in having a focused session on the topic. This became the theme for session four ( 13 ), where presenters and participants shared regional and context-specific challenges and solutions. Global expert and audience contributions touched on key learnings that have since been documented in the literature ( 23 , 24 ) including the importance of just-in-time risk-communication training and evidence-based community engagement approaches that rely on understanding the behavioral and social drivers to increase uptake and decrease hesitancy ( 25 – 28 ).

During the clinics, Q&A sessions generated considerable interest among participants, especially in the use of innovative approaches to increase vaccine coverage. Although it is encouraging to learn of the many emerging innovations borne of the COVID-19 crisis, best practice still requires that innovations be piloted and evaluated before scale-up, to assure that the innovative initiatives are beneficial, cost-effective, locally appropriate and sustainable. Equally, documentation of the impact of different approaches used by countries has been important to inform and optimize their use in the longer term for COVID-19 vaccine deployment, for other emergency vaccine responses or for routine vaccination programs ( 29 ).

In addition to innovation, countries described and discussed how best practice vaccination strategies from established childhood (e.g., polio, measles) and adult (e.g., influenza) immunization programmes were used to improve COVID-19 vaccination uptake. For example, strong outreach or mobile immunization sessions were described as crucial in many settings to reach priority populations. This finding aligns with literature documenting the use of outreach and mobile vaccination units to promote equity and reach underserved populations both prior to ( 30 , 31 ) and during the pandemic ( 32 – 34 ). Moreover, enhanced engagement with private sector health providers expanded access to non-traditional or new vaccination sites. Strategic private sector engagement has been described elsewhere as an effective strategy for mass health emergency vaccination ( 35 ). During the pandemic, working collaboratively with different sectors in a whole-of-society approach was also highlighted in the global analysis of IARs conducted by WHO ( 36 ).

Established practice for one country might be innovation for another. Countries shared the mosaic of digital strategies reported subjectively to improve aspects of their vaccination programs: virtual training platforms; digital data management tools for tracking vaccine supply and distribution; electronic vaccination registries; electronic vaccination cards with sophisticated methods for authentication; digital platforms and social media for social mobilization, monitoring rumors, and infodemic management. Peer-to-peer learning on these practices allowed clinic participants the opportunity to seek support from country representatives or global partners to develop in-country capacity for the real-world implementation of evidenced-based strategies for digital applications across the immunization system from vaccine supply to delivery to monitoring to communications and community engagement. Evidence was beginning to accrue on use of these strategies prior to the pandemic ( 37 , 38 ) but has expanded greatly with the pressures of the COVID-19 vaccine rollout ( 39 , 40 ).

The development of this COVID-19 vaccination IAR (mini-cPIE) toolkit and the clinics initiated a new and collaborative process between the Health Security Preparedness Department and the Department of Immunization, Vaccines and Biologicals at WHO. The development process provided opportunities for relevant stakeholders and end-users at all organizational levels (global, regional, country) to provide feedback. WHO’s collaboration with Project ECHO’s academic team leveraged their global vCOP and interactive webinar production experience and added a new perspective for achieving the right balance of information sharing and peer-to-peer learning on global COVID-19 immunization. WHO often encourages countries to adopt a multi-sectoral, whole-of-government and whole-of-society approach to emergency preparedness and response. In this clinic series, WHO also followed this model from the design to the implementation.

Our analysis is limited by the fact that the response rates to the post-session and the post-series surveys were relatively low and cannot be generalized to all participants. For the post-series survey, this is likely related to the delay of almost a year after the completion of the clinics before the survey was conducted. It is possible that participants most likely to respond were those who experienced the greatest benefit. Regardless, the feedback provided by respondents indicates that the series may have prompted at least eight countries to conduct mini-cPIEs and many more felt the material shared led to positive change in practice.

Conclusion and future directions

The creation of this virtual global real-time learning forum allowed countries to connect and share their COVID-19 vaccine introduction and deployment challenges and successes during an acute global emergency. A similar approach can be used to share pertinent topics beyond vaccination in real-time in future public health emergencies. The mini-cPIE clinics have also served as a springboard for a subsequent community of learning addressing lessons learned on COVID-19 immunization practices beyond the mini-cPIE ( 41 ). Moving forward, it is critical to foster a culture of individual and collective learning within and between countries during a public health emergency to help accelerate the sharing of new knowledge, promising practices, and real-world implementation of evidenced based practices, with global health agencies such as WHO playing an important facilitating role.

There’s a New Covid Variant. What Will That Mean for Spring and Summer?

Experts are closely watching KP.2, now the leading variant.

• Share full article

By Dani Blum

For most of this year, the JN.1 variant of the coronavirus accounted for an overwhelming majority of Covid cases . But now, an offshoot variant called KP.2 is taking off. The variant, which made up just one percent of cases in the United States in mid-March, now makes up over a quarter.

KP.2 belongs to a subset of Covid variants that scientists have cheekily nicknamed “FLiRT,” drawn from the letters in the names of their mutations. They are descendants of JN.1, and KP.2 is “very, very close” to JN.1, said Dr. David Ho, a virologist at Columbia University. But Dr. Ho has conducted early lab tests in cells that suggest that slight differences in KP.2’s spike protein might make it better at evading our immune defenses and slightly more infectious than JN.1.

While cases currently don’t appear to be on the rise, researchers and physicians are closely watching whether the variant will drive a summer surge.

“I don’t think anybody’s expecting things to change abruptly, necessarily,” said Dr. Marc Sala, co-director of the Northwestern Medicine Comprehensive Covid-19 Center in Chicago. But KP.2 will most likely “be our new norm,’” he said. Here’s what to know.

The current spread of Covid

Experts said it would take several weeks to see whether KP.2 might lead to a rise in Covid cases, and noted that we have only a limited understanding of how the virus is spreading. Since the public health emergency ended , there is less robust data available on cases, and doctors said fewer people were using Covid tests.

But what we do know is reassuring: Despite the shift in variants, data from the C.D.C. suggests there are only “minimal ” levels of the virus circulating in wastewater nationally, and emergency department visits and hospitalizations fell between early March and late April.

“I don’t want to say that we already know everything about KP.2,” said Dr. Ziyad Al-Aly, the chief of research and development at the Veterans Affairs St. Louis Healthcare System. “But at this time, I’m not seeing any major indications of anything ominous.”

Protection from vaccines and past infections

Experts said that even if you had JN.1, you may still get reinfected with KP.2 — particularly if it’s been several months or longer since your last bout of Covid.

KP.2 could infect even people who got the most updated vaccine, Dr. Ho said, since that shot targets XBB.1.5, a variant that is notably different from JN.1 and its descendants. An early version of a paper released in April by researchers in Japan suggested that KP.2 might be more adept than JN.1 at infecting people who received the most recent Covid vaccine. (The research has not yet been peer-reviewed or published.) A spokesperson for the C.D.C. said the agency was continuing to monitor how vaccines perform against KP.2.

Still, the shot does provide some protection, especially against severe disease, doctors said, as do previous infections. At this point, there isn’t reason to believe that KP.2 would cause more severe illness than other strains, the C.D.C. spokesperson said. But people who are 65 and older, pregnant or immunocompromised remain at higher risk of serious complications from Covid.

Those groups, in particular, may want to get the updated vaccine if they haven’t yet, said Dr. Peter Chin-Hong, an infectious disease specialist at the University of California, San Francisco. The C.D.C. has recommended t hat people 65 and older who already received one dose of the updated vaccine get an additional shot at least four months later.

“Even though it’s the lowest level of deaths and hospitalizations we’ve seen, I’m still taking care of sick people with Covid,” he said. “And they all have one unifying theme, which is that they’re older and they didn’t get the latest shot.”

The latest on symptoms and long Covid

Doctors said that the symptoms of both KP.2 and JN.1 — which now makes up around 16 percent of cases — are most likely similar to those seen with other variants . These include sore throat, runny nose, coughing, head and body aches, fever, congestion, fatigue and in severe cases, shortness of breath. Fewer people lose their sense of taste and smell now than did at the start of the pandemic, but some people will still experience those symptoms.

Dr. Chin-Hong said that patients were often surprised that diarrhea, nausea and vomiting could be Covid symptoms as well, and that they sometimes confused those issues as signs that they had norovirus .

For many people who’ve already had Covid, a reinfection is often as mild or milder than their first case. While new cases of long Covid are less common now than they were at the start of the pandemic, repeat infections do raise the risk of developing long Covid, said Fikadu Tafesse, a virologist at Oregon Health & Science University. But researchers are still trying to determine by how much — one of many issues scientists are trying to untangle as the pandemic continues to evolve.

“That’s the nature of the virus,” Dr. Tafesse said. “It keeps mutating.”
