COVID-19 Pandemic

By: History.com Editors

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

COVID-19

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

New York City's famous Times Square is seen nearly empty due to the COVID-19 pandemic on March 16, 2020.

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

Thousands gather for the ''Get Your Knee Off Our Necks'' march in Washington DC USA, on August 28, 2020.

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.

8 Lessons We Can Learn From the COVID-19 Pandemic

BY KATHY KATELLA May 14, 2021

Rear view of a family standing on a hill in autumn day, symbolizing hope for the end of the COVID-19 pandemic

Note: Information in this article was accurate at the time of original publication. Because information about COVID-19 changes rapidly, we encourage you to visit the websites of the Centers for Disease Control & Prevention (CDC), World Health Organization (WHO), and your state and local government for the latest information.

The COVID-19 pandemic changed life as we know it—and it may have changed us individually as well, from our morning routines to our life goals and priorities. Many say the world has changed forever. But this coming year, if the vaccines drive down infections and variants are kept at bay, life could return to some form of normal. At that point, what will we glean from the past year? Are there silver linings or lessons learned?

“Humanity's memory is short, and what is not ever-present fades quickly,” says Manisha Juthani, MD , a Yale Medicine infectious diseases specialist. The bubonic plague, for example, ravaged Europe in the Middle Ages—resurfacing again and again—but once it was under control, people started to forget about it, she says. “So, I would say one major lesson from a public health or infectious disease perspective is that it’s important to remember and recognize our history. This is a period we must remember.”

We asked our Yale Medicine experts to weigh in on what they think are lessons worth remembering, including those that might help us survive a future virus or nurture a resilience that could help with life in general.

Lesson 1: Masks are useful tools

What happened: The Centers for Disease Control and Prevention (CDC) relaxed its masking guidance for those who have been fully vaccinated. But when the pandemic began, it necessitated a global effort to ensure that everyone practiced behaviors to keep themselves healthy and safe—and keep others healthy as well. This included the widespread wearing of masks indoors and outside.

What we’ve learned: Not everyone practiced preventive measures such as mask wearing, maintaining a 6-foot distance, and washing hands frequently. But, Dr. Juthani says, “I do think many people have learned a whole lot about respiratory pathogens and viruses, and how they spread from one person to another, and that sort of old-school common sense—you know, if you don’t feel well—whether it’s COVID-19 or not—you don’t go to the party. You stay home.”

Masks are a case in point. They are a key COVID-19 prevention strategy because they provide a barrier that can keep respiratory droplets from spreading. Mask-wearing became more common across East Asia after the 2003 SARS outbreak in that part of the world. “There are many East Asian cultures where the practice is still that if you have a cold or a runny nose, you put on a mask,” Dr. Juthani says.

She hopes attitudes in the U.S. will shift in that direction after COVID-19. “I have heard from a number of people who are amazed that we've had no flu this year—and they know masks are one of the reasons,” she says. “They’ve told me, ‘When the winter comes around, if I'm going out to the grocery store, I may just put on a mask.’”

Lesson 2: Telehealth might become the new normal

What happened: Doctors and patients who have used telehealth (technology that allows them to conduct medical care remotely), found it can work well for certain appointments, ranging from cardiology check-ups to therapy for a mental health condition. Many patients who needed a medical test have also discovered it may be possible to substitute a home version.

What we’ve learned: While there are still problems for which you need to see a doctor in person, the pandemic introduced a new urgency to what had been a gradual switchover to platforms like Zoom for remote patient visits. 

More doctors also encouraged patients to track their blood pressure at home , and to use at-home equipment for such purposes as diagnosing sleep apnea and even testing for colon cancer . Doctors also can fine-tune cochlear implants remotely .

“It happened very quickly,” says Sharon Stoll, DO, a neurologist. One group that has benefitted is patients who live far away, sometimes in other parts of the country—or even the world, she says. “I always like to see my patients at least twice a year. Now, we can see each other in person once a year, and if issues come up, we can schedule a telehealth visit in-between,” Dr. Stoll says. “This way I may hear about an issue before it becomes a problem, because my patients have easier access to me, and I have easier access to them.”

Meanwhile, insurers are becoming more likely to cover telehealth, Dr. Stoll adds. “That is a silver lining that will hopefully continue.”

Lesson 3: Vaccines are powerful tools

What happened: Given the recent positive results from vaccine trials, once again vaccines are proving to be powerful for preventing disease.

What we’ve learned: Vaccines really are worth getting, says Dr. Stoll, who had COVID-19 and experienced lingering symptoms, including chronic headaches . “I have lots of conversations—and sometimes arguments—with people about vaccines,” she says. Some don’t like the idea of side effects. “I had vaccine side effects and I’ve had COVID-19 side effects, and I say nothing compares to the actual illness. Unfortunately, I speak from experience.”

Dr. Juthani hopes the COVID-19 vaccine spotlight will motivate people to keep up with all of their vaccines, including childhood and adult vaccines for such diseases as measles , chicken pox, shingles , and other viruses. She says people have told her they got the flu vaccine this year after skipping it in previous years. (The CDC has reported distributing an exceptionally high number of doses this past season.)  

But, she cautions that a vaccine is not a magic bullet—and points out that scientists can’t always produce one that works. “As advanced as science is, there have been multiple failed efforts to develop a vaccine against the HIV virus,” she says. “This time, we were lucky that we were able build on the strengths that we've learned from many other vaccine development strategies to develop multiple vaccines for COVID-19 .” 

Lesson 4: Everyone is not treated equally, especially in a pandemic

What happened: COVID-19 magnified disparities that have long been an issue for a variety of people.

What we’ve learned: Racial and ethnic minority groups especially have had disproportionately higher rates of hospitalization for COVID-19 than non-Hispanic white people in every age group, and many other groups faced higher levels of risk or stress. These groups ranged from working mothers who also have primary responsibility for children, to people who have essential jobs, to those who live in rural areas where there is less access to health care.

“One thing that has been recognized is that when people were told to work from home, you needed to have a job that you could do in your house on a computer,” says Dr. Juthani. “Many people who were well off were able do that, but they still needed to have food, which requires grocery store workers and truck drivers. Nursing home residents still needed certified nursing assistants coming to work every day to care for them and to bathe them.”  

As far as racial inequities, Dr. Juthani cites President Biden’s appointment of Yale Medicine’s Marcella Nunez-Smith, MD, MHS , as inaugural chair of a federal COVID-19 Health Equity Task Force. “Hopefully the new focus is a first step,” Dr. Juthani says.

Lesson 5: We need to take mental health seriously

What happened: There was a rise in reported mental health problems that have been described as “a second pandemic,” highlighting mental health as an issue that needs to be addressed.

What we’ve learned: Arman Fesharaki-Zadeh, MD, PhD , a behavioral neurologist and neuropsychiatrist, believes the number of mental health disorders that were on the rise before the pandemic is surging as people grapple with such matters as juggling work and childcare, job loss, isolation, and losing a loved one to COVID-19.

The CDC reports that the percentage of adults who reported symptoms of anxiety of depression in the past 7 days increased from 36.4 to 41.5 % from August 2020 to February 2021. Other reports show that having COVID-19 may contribute, too, with its lingering or long COVID symptoms, which can include “foggy mind,” anxiety , depression, and post-traumatic stress disorder .

 “We’re seeing these problems in our clinical setting very, very often,” Dr. Fesharaki-Zadeh says. “By virtue of necessity, we can no longer ignore this. We're seeing these folks, and we have to take them seriously.”

Lesson 6: We have the capacity for resilience

What happened: While everyone’s situation is different­­ (and some people have experienced tremendous difficulties), many have seen that it’s possible to be resilient in a crisis.

What we’ve learned: People have practiced self-care in a multitude of ways during the pandemic as they were forced to adjust to new work schedules, change their gym routines, and cut back on socializing. Many started seeking out new strategies to counter the stress.

“I absolutely believe in the concept of resilience, because we have this effective reservoir inherent in all of us—be it the product of evolution, or our ancestors going through catastrophes, including wars, famines, and plagues,” Dr. Fesharaki-Zadeh says. “I think inherently, we have the means to deal with crisis. The fact that you and I are speaking right now is the result of our ancestors surviving hardship. I think resilience is part of our psyche. It's part of our DNA, essentially.”

Dr. Fesharaki-Zadeh believes that even small changes are highly effective tools for creating resilience. The changes he suggests may sound like the same old advice: exercise more, eat healthy food, cut back on alcohol, start a meditation practice, keep up with friends and family. “But this is evidence-based advice—there has been research behind every one of these measures,” he says.

But we have to also be practical, he notes. “If you feel overwhelmed by doing too many things, you can set a modest goal with one new habit—it could be getting organized around your sleep. Once you’ve succeeded, move on to another one. Then you’re building momentum.”

Lesson 7: Community is essential—and technology is too

What happened: People who were part of a community during the pandemic realized the importance of human connection, and those who didn’t have that kind of support realized they need it.

What we’ve learned: Many of us have become aware of how much we need other people—many have managed to maintain their social connections, even if they had to use technology to keep in touch, Dr. Juthani says. “There's no doubt that it's not enough, but even that type of community has helped people.”

Even people who aren’t necessarily friends or family are important. Dr. Juthani recalled how she encouraged her mail carrier to sign up for the vaccine, soon learning that the woman’s mother and husband hadn’t gotten it either. “They are all vaccinated now,” Dr. Juthani says. “So, even by word of mouth, community is a way to make things happen.”

It’s important to note that some people are naturally introverted and may have enjoyed having more solitude when they were forced to stay at home—and they should feel comfortable with that, Dr. Fesharaki-Zadeh says. “I think one has to keep temperamental tendencies like this in mind.”

But loneliness has been found to suppress the immune system and be a precursor to some diseases, he adds. “Even for introverted folks, the smallest circle is preferable to no circle at all,” he says.

Lesson 8: Sometimes you need a dose of humility

What happened: Scientists and nonscientists alike learned that a virus can be more powerful than they are. This was evident in the way knowledge about the virus changed over time in the past year as scientific investigation of it evolved.

What we’ve learned: “As infectious disease doctors, we were resident experts at the beginning of the pandemic because we understand pathogens in general, and based on what we’ve seen in the past, we might say there are certain things that are likely to be true,” Dr. Juthani says. “But we’ve seen that we have to take these pathogens seriously. We know that COVID-19 is not the flu. All these strokes and clots, and the loss of smell and taste that have gone on for months are things that we could have never known or predicted. So, you have to have respect for the unknown and respect science, but also try to give scientists the benefit of the doubt,” she says.

“We have been doing the best we can with the knowledge we have, in the time that we have it,” Dr. Juthani says. “I think most of us have had to have the humility to sometimes say, ‘I don't know. We're learning as we go.’"

Understanding COVID-19

How To Protect Yourself During the Pandemic

Illustration of two men wearing masks while sitting on park benches six feet apart

COVID-19 has claimed millions of lives around the world. But we learn more about this disease every day. Scientists are developing tools that promise to slow and eventu­ally help us overcome the pandemic.

COVID-19 is caused by a new coronavirus called SARS-CoV-2. There are many types of coronaviruses. Some cause the common cold. Others have led to fatal disease outbreaks. These include severe acute respiratory syndrome (SARS) in 2003, Middle East respiratory syndrome (MERS) in 2012, and now COVID-19.

Coronaviruses are named for the crown-like spikes on their surface. (Corona means crown.) The viruses use the spikes to help get inside your body’s cells. Once inside, they replicate, or make copies of themselves.

Scientists have learned how to turn these spikes against the virus through vaccines and treatments. They’ve also learned what you can do to protect yourself from the virus.

Protecting Yourself

You’re most likely to get COVID-19 through close contact with someone who’s infected. Coughing, sneezing, talking, and breathing produce small droplets of liquid. These are called respiratory droplets. They travel through the air and can be inhaled by someone else.

“COVID-19 is spread mainly through exposure to respiratory droplets that tend to drop within six feet,” says Dr. Anthony Fauci, director of NIH’s National Institute of Allergy and Infectious Diseases. That’s why it’s important to stay at least six feet (about two arm lengths) away from people who don’t live with you.

“Surfaces can be contaminated. But it is likely that this is a less common cause of infection rather than person-to-person directly,” Fauci says.

You can protect yourself and others by wearing a mask. Choose one that has at least two layers of fabric. Make sure that the mask covers your mouth and nose and doesn’t leak air around the edges.

“There’s very little transmission in places where masks are worn,” says Dr. Ben Cowling at the University of Hong Kong who studies how viruses spread. Cowling found that infections were most often spread in settings where masks aren’t worn.

“Masks work. But even with mandatory masking, you still need social distancing as well,” he says. You can lower your risk by avoiding crowds. Crowds increase the risk of coming in contact with someone who has COVID-19.

What to Look For

Common symptoms of COVID-19 include fever, cough, headaches, fatigue, and muscle or body aches. People with COVID-19 may also lose their sense of smell or taste. Symptoms usually appear two to 14 days after being exposed to the virus.

But even people who don’t seem sick can still infect others. The CDC estimates that 50% of infections are spread by people with no symptoms. While some with this virus develop life-threatening illness, others have mild symptoms, and some never develop any.

Catching the virus is more dangerous for some groups of people. This includes older adults and people with certain medical conditions. These medical conditions include obesity, diabetes, heart and lung disease, and asthma. About 40% of Americans have at least one of these risk factors.

Getting Treatment

Better COVID-19 treatments mean that fewer people now get severely sick if they catch the virus. Scientists have been working to test available drugs against the virus. They’ve found at least two that can help people who are hospitalized with the virus.

A drug called remdesivir can reduce the time a patient spends in the hospital. A steroid called dexamethasone helps stop the The system that protects your body from invading viruses, bacteria, and other microscopic threats. immune system from reacting too strongly to the virus. That can damage body tissues and organs.

Antibody treatments are also available. Antibodies are proteins that your body makes to fight germs. Scientists have learned how to make them in the lab. Antibody treatments can block SARS-CoV-2 to prevent the illness from getting worse. They seem to have the most benefit when given early in the disease.

“Antibody treatments really do have the potential to help people, especially for treating individuals who are not yet hospitalized,” says Dr. Mark Heise, who studies the genetics of viruses at the University of North Carolina at Chapel Hill. Heise is working to develop mouse models to test treatments and vaccines.

Studies are now testing combinations of treatments. “Combining drugs that target both the virus and the person’s immune response may help treat COVID-19,” says Heise. Scientists are also looking for new drugs that better target the virus.

A Shot of Hope: Vaccines

It used to take a decade or more to develop a new vaccine. In this pandemic, scientists created COVID-19 vaccines in less than a year.

The first two vaccines approved for emergency use are from Moderna and Pfizer/BioNTech. Moderna’s vaccine was co-developed with NIH scientists. Both are a new type of vaccine called mRNA vaccines. mRNA carries the genetic information for your body to make proteins.

The vaccines direct the body’s cells to make a piece of the virus called the spike protein. These proteins can’t cause illness by themselves. But they teach your immune system to make antibodies against the protein. If you encounter the virus later, the antibodies provide protection against it.

The mRNA vaccines now available were shown to be more than 90% effective in large clinical trials. They can cause side effects—such as fatigue, muscle aches, joint pain, and headache. But both vaccines were found to be safe in the clinical trials.

“Get vaccinated. The vaccines are safe. They’re incredibly effective,” says Dr. Jason McLellan, an expert on coronaviruses at the University of Texas at Austin. McLellan’s research was critical in developing these vaccines. His team, along with NIH scientists, figured out how to lock the shape of the spike protein to make the most effective antibodies.

As the pandemic has gone on, new versions of the virus, or variants, have appeared. “We’re all very confident that vaccines will continue to work well against these variants,” McLellan says. “Vaccination also helps stop the development of new variants, because it provides fewer opportunities for the virus to change as it replicates.”

Many people will need to be vaccinated for the pandemic to end. Fauci estimates that 70% to 85% of the U.S. population will need to be vaccinated to get “herd immunity.” That’s the point where enough people are immune to the virus to prevent its spread. That’s important because it protects vulnerable people who can’t get vaccinated.

“It is my hope that all Americans will protect themselves by getting vaccinated when the vaccine becomes available to them,” Fauci says. “That is how our country will begin to heal and move forward.”

Read these 12 moving essays about life during coronavirus

Artists, novelists, critics, and essayists are writing the first draft of history.

by Alissa Wilkinson

A woman wearing a face mask in Miami.

The world is grappling with an invisible, deadly enemy, trying to understand how to live with the threat posed by a virus . For some writers, the only way forward is to put pen to paper, trying to conceptualize and document what it feels like to continue living as countries are under lockdown and regular life seems to have ground to a halt.

So as the coronavirus pandemic has stretched around the world, it’s sparked a crop of diary entries and essays that describe how life has changed. Novelists, critics, artists, and journalists have put words to the feelings many are experiencing. The result is a first draft of how we’ll someday remember this time, filled with uncertainty and pain and fear as well as small moments of hope and humanity.

  • The Vox guide to navigating the coronavirus crisis

At the New York Review of Books, Ali Bhutto writes that in Karachi, Pakistan, the government-imposed curfew due to the virus is “eerily reminiscent of past military clampdowns”:

Beneath the quiet calm lies a sense that society has been unhinged and that the usual rules no longer apply. Small groups of pedestrians look on from the shadows, like an audience watching a spectacle slowly unfolding. People pause on street corners and in the shade of trees, under the watchful gaze of the paramilitary forces and the police.

His essay concludes with the sobering note that “in the minds of many, Covid-19 is just another life-threatening hazard in a city that stumbles from one crisis to another.”

Writing from Chattanooga, novelist Jamie Quatro documents the mixed ways her neighbors have been responding to the threat, and the frustration of conflicting direction, or no direction at all, from local, state, and federal leaders:

Whiplash, trying to keep up with who’s ordering what. We’re already experiencing enough chaos without this back-and-forth. Why didn’t the federal government issue a nationwide shelter-in-place at the get-go, the way other countries did? What happens when one state’s shelter-in-place ends, while others continue? Do states still under quarantine close their borders? We are still one nation, not fifty individual countries. Right?

Award-winning photojournalist Alessio Mamo, quarantined with his partner Marta in Sicily after she tested positive for the virus, accompanies his photographs in the Guardian of their confinement with a reflection on being confined :

The doctors asked me to take a second test, but again I tested negative. Perhaps I’m immune? The days dragged on in my apartment, in black and white, like my photos. Sometimes we tried to smile, imagining that I was asymptomatic, because I was the virus. Our smiles seemed to bring good news. My mother left hospital, but I won’t be able to see her for weeks. Marta started breathing well again, and so did I. I would have liked to photograph my country in the midst of this emergency, the battles that the doctors wage on the frontline, the hospitals pushed to their limits, Italy on its knees fighting an invisible enemy. That enemy, a day in March, knocked on my door instead.

In the New York Times Magazine, deputy editor Jessica Lustig writes with devastating clarity about her family’s life in Brooklyn while her husband battled the virus, weeks before most people began taking the threat seriously:

At the door of the clinic, we stand looking out at two older women chatting outside the doorway, oblivious. Do I wave them away? Call out that they should get far away, go home, wash their hands, stay inside? Instead we just stand there, awkwardly, until they move on. Only then do we step outside to begin the long three-block walk home. I point out the early magnolia, the forsythia. T says he is cold. The untrimmed hairs on his neck, under his beard, are white. The few people walking past us on the sidewalk don’t know that we are visitors from the future. A vision, a premonition, a walking visitation. This will be them: Either T, in the mask, or — if they’re lucky — me, tending to him.

Essayist Leslie Jamison writes in the New York Review of Books about being shut away alone in her New York City apartment with her 2-year-old daughter since she became sick:

The virus. Its sinewy, intimate name. What does it feel like in my body today? Shivering under blankets. A hot itch behind the eyes. Three sweatshirts in the middle of the day. My daughter trying to pull another blanket over my body with her tiny arms. An ache in the muscles that somehow makes it hard to lie still. This loss of taste has become a kind of sensory quarantine. It’s as if the quarantine keeps inching closer and closer to my insides. First I lost the touch of other bodies; then I lost the air; now I’ve lost the taste of bananas. Nothing about any of these losses is particularly unique. I’ve made a schedule so I won’t go insane with the toddler. Five days ago, I wrote Walk/Adventure! on it, next to a cut-out illustration of a tiger—as if we’d see tigers on our walks. It was good to keep possibility alive.

At Literary Hub, novelist Heidi Pitlor writes about the elastic nature of time during her family’s quarantine in Massachusetts:

During a shutdown, the things that mark our days—commuting to work, sending our kids to school, having a drink with friends—vanish and time takes on a flat, seamless quality. Without some self-imposed structure, it’s easy to feel a little untethered. A friend recently posted on Facebook: “For those who have lost track, today is Blursday the fortyteenth of Maprilay.” ... Giving shape to time is especially important now, when the future is so shapeless. We do not know whether the virus will continue to rage for weeks or months or, lord help us, on and off for years. We do not know when we will feel safe again. And so many of us, minus those who are gifted at compartmentalization or denial, remain largely captive to fear. We may stay this way if we do not create at least the illusion of movement in our lives, our long days spent with ourselves or partners or families.
  • What day is it today?

Novelist Lauren Groff writes at the New York Review of Books about trying to escape the prison of her fears while sequestered at home in Gainesville, Florida:

Some people have imaginations sparked only by what they can see; I blame this blinkered empiricism for the parks overwhelmed with people, the bars, until a few nights ago, thickly thronged. My imagination is the opposite. I fear everything invisible to me. From the enclosure of my house, I am afraid of the suffering that isn’t present before me, the people running out of money and food or drowning in the fluid in their lungs, the deaths of health-care workers now growing ill while performing their duties. I fear the federal government, which the right wing has so—intentionally—weakened that not only is it insufficient to help its people, it is actively standing in help’s way. I fear we won’t sufficiently punish the right. I fear leaving the house and spreading the disease. I fear what this time of fear is doing to my children, their imaginations, and their souls.

At ArtForum , Berlin-based critic and writer Kristian Vistrup Madsen reflects on martinis, melancholia, and Finnish artist Jaakko Pallasvuo’s 2018 graphic novel Retreat , in which three young people exile themselves in the woods:

In melancholia, the shape of what is ending, and its temporality, is sprawling and incomprehensible. The ambivalence makes it hard to bear. The world of Retreat is rendered in lush pink and purple watercolors, which dissolve into wild and messy abstractions. In apocalypse, the divisions established in genesis bleed back out. My own Corona-retreat is similarly soft, color-field like, each day a blurred succession of quarantinis, YouTube–yoga, and televized press conferences. As restrictions mount, so does abstraction. For now, I’m still rooting for love to save the world.

At the Paris Review , Matt Levin writes about reading Virginia Woolf’s novel The Waves during quarantine:

A retreat, a quarantine, a sickness—they simultaneously distort and clarify, curtail and expand. It is an ideal state in which to read literature with a reputation for difficulty and inaccessibility, those hermetic books shorn of the handholds of conventional plot or characterization or description. A novel like Virginia Woolf’s The Waves is perfect for the state of interiority induced by quarantine—a story of three men and three women, meeting after the death of a mutual friend, told entirely in the overlapping internal monologues of the six, interspersed only with sections of pure, achingly beautiful descriptions of the natural world, a day’s procession and recession of light and waves. The novel is, in my mind’s eye, a perfectly spherical object. It is translucent and shimmering and infinitely fragile, prone to shatter at the slightest disturbance. It is not a book that can be read in snatches on the subway—it demands total absorption. Though it revels in a stark emotional nakedness, the book remains aloof, remote in its own deep self-absorption.

In an essay for the Financial Times, novelist Arundhati Roy writes with anger about Indian Prime Minister Narendra Modi’s anemic response to the threat, but also offers a glimmer of hope for the future:

Historically, pandemics have forced humans to break with the past and imagine their world anew. This one is no different. It is a portal, a gateway between one world and the next. We can choose to walk through it, dragging the carcasses of our prejudice and hatred, our avarice, our data banks and dead ideas, our dead rivers and smoky skies behind us. Or we can walk through lightly, with little luggage, ready to imagine another world. And ready to fight for it.

From Boston, Nora Caplan-Bricker writes in The Point about the strange contraction of space under quarantine, in which a friend in Beirut is as close as the one around the corner in the same city:

It’s a nice illusion—nice to feel like we’re in it together, even if my real world has shrunk to one person, my husband, who sits with his laptop in the other room. It’s nice in the same way as reading those essays that reframe social distancing as solidarity. “We must begin to see the negative space as clearly as the positive, to know what we don’t do is also brilliant and full of love,” the poet Anne Boyer wrote on March 10th, the day that Massachusetts declared a state of emergency. If you squint, you could almost make sense of this quarantine as an effort to flatten, along with the curve, the distinctions we make between our bonds with others. Right now, I care for my neighbor in the same way I demonstrate love for my mother: in all instances, I stay away. And in moments this month, I have loved strangers with an intensity that is new to me. On March 14th, the Saturday night after the end of life as we knew it, I went out with my dog and found the street silent: no lines for restaurants, no children on bicycles, no couples strolling with little cups of ice cream. It had taken the combined will of thousands of people to deliver such a sudden and complete emptiness. I felt so grateful, and so bereft.

And on his own website, musician and artist David Byrne writes about rediscovering the value of working for collective good , saying that “what is happening now is an opportunity to learn how to change our behavior”:

In emergencies, citizens can suddenly cooperate and collaborate. Change can happen. We’re going to need to work together as the effects of climate change ramp up. In order for capitalism to survive in any form, we will have to be a little more socialist. Here is an opportunity for us to see things differently — to see that we really are all connected — and adjust our behavior accordingly. Are we willing to do this? Is this moment an opportunity to see how truly interdependent we all are? To live in a world that is different and better than the one we live in now? We might be too far down the road to test every asymptomatic person, but a change in our mindsets, in how we view our neighbors, could lay the groundwork for the collective action we’ll need to deal with other global crises. The time to see how connected we all are is now.

The portrait these writers paint of a world under quarantine is multifaceted. Our worlds have contracted to the confines of our homes, and yet in some ways we’re more connected than ever to one another. We feel fear and boredom, anger and gratitude, frustration and strange peace. Uncertainty drives us to find metaphors and images that will let us wrap our minds around what is happening.

Yet there’s no single “what” that is happening. Everyone is contending with the pandemic and its effects from different places and in different ways. Reading others’ experiences — even the most frightening ones — can help alleviate the loneliness and dread, a little, and remind us that what we’re going through is both unique and shared by all.

Lessons we will learn from this pandemic, unicef young reporters shed light on the lessons they have learned during the covid-19 pandemic.

Eva Hadzipetrova

There is no rainbow without rain

Eva Hadzipetrova (15), UNICEF Young Reporter

I’ve been thinking a lot - what is it that will come out of all this? Equality! This situation has shown us that we are all the same regardless of our religion, culture, customs, whether we are poor or rich. The virus simply does not choose. It connected us in a way, it showed us that we should all stick together. During this chaos, while many of us in a panic, it showed us the weight of humanity. It reminded us who we are. Maybe the world will finally change.

We humans are fragile by ourselves. Our strength lies in being part of a community.

We do not live without relationships and we should never forget that. We have a very caring and shared connection between us and it’s amazing to see how we stick together at times. Sharing is caring. Sometimes we need to remember how important kindness is. We need to remember that we have been given a gift called life and that we should appreciate it.

Everything can end tomorrow. Focus on what is important to us. When all this is over, Earth will continue to spin, and life will flow again. The question is whether by then we will have learned our lesson. Let us be mindful of our Earth and it will be kind to us. There is no rainbow without rain. Remember that.

Maria Mitrikeska

There is good in every evil

Maria Mitrikeska (15), UNICEF Young Reporter

There is an old saying ‘there is good in every evil’ that I will now use as a tiny consolation in this difficult, unexpected time. As a young teenager, believe me it is hard dealing with this situation, and to everyone who is reading this and feeling helpless, I just want to tell you that you are not alone, and it will be better!

I am aware of everything that has been taken away from us due to this situation, of all the unrealized plans, be it birthdays, travels, weddings ... and sadly, we cannot do anything about it. But we are not powerless! On the contrary, it is all of us together that can make the world a better place. If each of us respects the measures imposed by authorities, the situation will get better and it will pass much faster than expected.

I can single out isolation - staying at home – as one of the most important measures. I know it sounds difficult and believe me, at first this sounded impossible to me, just unfeasible. I found it hard and boring, I wasn’t used to sitting in the same closed place for so long. But over time, I started to find hobbies. I tried things I had never tried before. I spent a lot more time with my parents than before, and even though I didn’t go out, I exercised at home. I found I had the time to watch the TV series and read books I never had the time for! Also, I have to admit that for me, online learning is much easier, more flexible and stress-free.

One of the most important things I’ve learned while we’re in isolation is to take care of myself and to devote more time to myself.

Taking care of yourself is something so underestimated nowadays. Whether due to a lack of time or due to too much stress in everyday life or for a whatever reason, people don’t devote enough time to themselves. While in isolation, I’ve had a lot of time to think and realize that actually taking care of myself is one of the things that makes me happy. I mean little things that I believe are available to everyone. These little things are actually the ones that help me find myself.

Let’s go back to the sentence “There is good in every evil”. A simple short sentence, but still so powerful! This is just one perspective of a young girl who is going through the same thing as many others. So don’t forget, you’re never alone!

Branislav Maksimovski

A pandemic that taught me to love

Branislav Maksimovski (15), UNICEF Young Reporter

It’ll take just a little patience and support for us to master this crisis, but together can we do it. We only need to respect the recommendations and measures issued by the state, to protect ourselves, the people closest to us, and others who live in our community. We all know that it is not easy to stay at home but taking a break to stop and reflect has its own virtues.

If someone asks me how I’m dealing with the pandemic and how it influences me I would say:

I know that is not easy for us, I know it’s not easy for those lying in the hospitals, I know it’s not easy for those who lost someone. Life takes us in different directions. That’s why it’s important to live the moment, without thinking of the past or the future. I sit at home, do my school assignments, go out on the balcony, have a tee or coffee, listen to good music. I can’t count all the activities I do to stay positive. It matters to me that my brother, my parents and grandparents are safe and for them I do my best. I write essays, I paint, I read.  This situation has taught me many things.

It taught me to love, to listen, to care, to respect and to help.

Help - that’s the word I’m looking for. What does it mean “to help someone”? Help someone to teach them something. Help someone by having a conversation with them. We should use this word in our vocabulary more often, so we can see a smile on people’s faces more often. This situation taught me to love. Not only to love a person, but also to love the little things in life.

Adrijana Kamcheva

Life is a lesson, we learn and continue to learn every day

Andrijana Kamcheva (25), UNICEF Young Reporter

Humans are very complex beings; they spend their whole life learning. But why wait for something bad to happen so that we learn how to appreciate the good? Why can’t we appreciate the little things that actually make us happy?

I never had a chance to think about the things that have happened to me. I wasn’t appreciating many things and I have given importance to so many things, which weren’t important at all. I didn’t know that the rain makes me happy or that the coffee I have on the balcony is tastier than the coffee in a coffee shop. I realize that reading books makes me happy. Playing cards and monopoly at home wasn’t that bad at all and working out at home is better that at a gym.  I realized that I’m a philanthropist and have a great sense of empathy, which makes me very happy.

We learn how to live every day. We choose the path we will take.

Just think about everything you dream of? It is good that we dream and work towards achieving a goal. Don’t be afraid to work miracles on yourself, don’t be afraid to live as you deserve. Its normal to come across obstacles, that’s how we learn when we overcome challenges.

Life is a lesson; we learn every day and we will continue learning every day. Everything doesn’t have to be perfect in life for us to be happy and to appreciate ourselves and everything around us.  We just have to be greatful. Remember that the best life lesson is learned during hard times and when we make mistakes.

Enjoy your life and appreciate what you have. Just think about the fact that there are people in the world with less. Be happy and positive for everything around you and you will become a stonger person.

COVID-19 pandemic

Recent News

On February 25, 2020, a top official at the Centers for Disease Control and Prevention decided it was time to level with the U.S. public about the COVID-19 outbreak. At the time, there were just 57 people in the country confirmed to have the infection, all but 14 having been repatriated from Hubei province in China and the Diamond Princess cruise ship , docked off Yokohama , Japan .

The infected were in quarantine. But Nancy Messonnier, then head of the CDC’s National Center for Immunization and Respiratory Diseases, knew what was coming. “It’s not so much a question of if this will happen anymore but rather more a question of exactly when this will happen and how many people in this country will have severe illness,” Messonnier said at a news briefing.

“I understand this whole situation may seem overwhelming and that disruption to everyday life may be severe,” she continued. “But these are things that people need to start thinking about now.”

Looking back, the COVID-19 pandemic stands as arguably the most disruptive event of the 21st century, surpassing wars, the September 11, 2001, terrorist attacks , the effects of climate change , and the Great Recession . It has killed more than seven million people to date and reshaped the world economy, public health , education, work, social interaction, family life, medicine, and mental health—leaving no corner of the globe untouched in some way. Now endemic in many societies, the consistently mutating virus remains one of the leading annual causes of death, especially among people older than 65 and the immunosuppressed.

“The coronavirus outbreak, historically, beyond a doubt, has been the most devastating pandemic of an infectious disease that global society has experienced in well over 100 years, since the 1918 influenza pandemic ,” Anthony Fauci , who helped lead the U.S. government’s health response to the pandemic under Pres. Donald Trump and became Pres. Joe Biden ’s chief medical adviser, told Encyclopædia Britannica in 2024.

“I think the impact of this outbreak on the world in general, on the United States , is really historic. Fifty years from now, 100 years from now, when they talk about the history of what we’ve been through, this is going to go down equally with the 1918 influenza pandemic , with the stock market crash of 1929 , with World War II —all the things that were profoundly disruptive of the social order.”

What few could imagine in the first days of the pandemic was the extent of the disruption the disease would bring to the everyday lives of just about everyone around the globe.

Within weeks, schools and child-care centers began shuttering, businesses sent their workforces home, public gatherings were canceled, stores and restaurants closed, and cruise ships were barred from sailing. On March 11, actor Tom Hanks announced that he had COVID-19, and the NBA suspended its season. (It was ultimately completed in a closed “bubble” at Walt Disney World .) On March 12, as college basketball players left courts mid-game during conference tournaments, the NCAA announced that it would not hold its wildly popular season-ending national competition, known as March Madness , for the first time since 1939. Three days later, the New York City public school system, the country’s largest, with 1.1 million students, closed. On March 19, all 40 million Californians were placed under a stay-at-home order.

By mid-April, with hospital beds and ventilators in critically short supply, workers were burying the coffins of COVID-19 victims in mass graves on Hart Island, off the Bronx . At first, the public embraced caregivers. New Yorkers applauded them from windows and balconies, and individuals sewed masks for them. But that spirit soon gave way to the crushing long-term reality of the pandemic and the national division that followed.

Around the world, it was worse. On the day Messonnier spoke, the virus had spread from its origin point in Wuhan , China, to at least two dozen countries, sickening thousands and killing dozens. By April 4, more than one million cases had been confirmed worldwide. Some countries, including China and Italy, imposed strict lockdowns on their citizens. Paris restricted movement, with certain exceptions, including an hour a day for exercise, within 1 km (0.62 mile) of home.

In the United States, the threat posed by the virus did not keep large crowds from gathering to protest the May 25 slaying of George Floyd , a 46-year-old Black man, by a white police officer, Derek Chauvin. The murder, taped by a bystander in Minneapolis , Minnesota , sparked raucous and sometimes violent street protests for racial justice around the world that contributed to an overall sense of societal instability.

The official World Health Organization total of more than seven million deaths as of March 2024 is widely considered a serious undercount of the actual toll. In some countries there was limited testing for the virus and difficulty attributing fatalities to it. Others suppressed total counts or were not able to devote resources to compiling their totals. In May 2021, a panel of experts consulted by The New York Times estimated that India ’s actual COVID-19 death toll was likely 1.6 million, more than five times the reported total of 307,231.

An average of 3,100 people—one every 28 seconds—died of COVID-19 every day in the United States in January 2021.

When “excess mortality”—COVID and non-COVID deaths that likely would not have occurred under normal, pre-outbreak conditions—are included in the worldwide tally, the number of pandemic victims was about 15 million by the end of 2021, WHO estimated.

Not long after the pandemic took hold, the United States, which spends more per capita on medical care than any other country, became the epicenter of COVID-19 fatalities. The country fell victim to a fractured health care system that is inequitable to poor and rural patients and people of color, as well as a deep ideological divide over its political leadership and public health policies, such as wearing protective face masks. By early 2024, the U.S. had recorded nearly 1.2 million COVID-19 deaths.

Life expectancy at birth plunged from 78.8 years in 2019 to 76.4 in 2021, a staggering decline in a barometer of a country’s health that typically changes by only a tenth or two annually. An average of 3,100 people—one every 28 seconds—died of COVID-19 every day in the United States in January 2021, before vaccines for the virus became widely available, The Washington Post reported.

The impact on those caring for the sick and dying was profound. “The second week of December [2020] was probably the worst week of my career,” said Brad Butcher, director of the medical-surgical intensive care unit at UPMC Mercy hospital in Pittsburgh , Pennsylvania. “The first day I was on service, five patients died in a shift. And then I came back the next day, and three patients died. And I came back the next day, and three more patients died. And it was completely defeating,” he told The Washington Post on January 11, 2021.

“We can’t get the graves dug fast enough,” a Maryland funeral home operator told The Washington Post that same day.

As the pandemic surged in waves around the world, country after country was plunged into economic recession , the inevitable damage caused by layoffs, business closures, lockdowns, deaths, reduced trade, debt repayment moratoriums , the cost to governments of responding to the crisis, and other factors. Overall, the virus triggered the greatest economic calamity in more than a century, according to a 2022 report by the World Bank .

“Economic activity contracted in 2020 in about 90 percent of countries, exceeding the number of countries seeing such declines during two world wars, the Great Depression of the 1930s, the emerging economy debt crises of the 1980s, and the 2007–09 global financial crisis,” the report noted. “In 2020, the first year of the COVID-19 pandemic, the global economy shrank by approximately 3 percent, and global poverty increased for the first time in a generation.”

A 2020 study that attempted to aggregate the costs of lost gross domestic product (GDP) estimated that premature deaths and health-related losses in the United States totaled more than $16 trillion, or roughly “90% of the annual GDP of the United States. For a family of 4, the estimated loss would be nearly $200,000.”

In April 2020, the U.S. unemployment rate stood at 14.7 percent, higher than at any point since the Great Depression. There were 23.1 million people out of work. The hospitality, leisure, and health care industries were especially hard hit. Consumer spending, which accounts for about two-thirds of the U.S. economy, plunged.

With workers at home, many businesses turned to telework, a development that would persist beyond the pandemic and radically change working conditions for millions. In 2023, 12.7 percent of full-time U.S. employees worked from home and 28.2 percent worked a hybrid office-home schedule, according to Forbes Advisor . Urban centers accustomed to large daily influxes of workers have suffered. Office vacancies are up, and small businesses have closed. The national office vacancy rate rose to a record 19.6 percent in the fourth quarter of 2023, according to Moody’s Analytics , which has been tracking the statistic since 1979.

Many hospitals were overwhelmed during COVID-19 surges, with too few beds for the flood of patients. But many also demonstrated their resilience and “surge capacity,” dramatically expanding bed counts in very short periods of time and finding other ways to treat patients in swamped medical centers. Triage units and COVID-19 wards were hastily erected in temporary structures on hospital grounds.

Still, U.S. hospitals suffered severe shortages of nurses and found themselves lacking basic necessities such as N95 masks and personal protective garb for the doctors, nurses, and other workers who risked their lives against the new pathogen at the start of the outbreak. Mortuaries and first responders were overwhelmed as well. The dead were kept in refrigerated trucks outside hospitals.

The country’s fragmented public health system proved inadequate to the task of coping with the outbreak, sparking calls for major reform of the CDC and other agencies. The CDC botched its initial attempt to create tests for the virus, leaving the United States almost blind to its spread during the early stages of the pandemic.

Beyond the physical dangers, mental health became a serious issue for overburdened health care personnel, other “essential” workers who continued to labor in crucial jobs, and many millions of isolated, stressed, fearful, locked-down people in the United States and elsewhere. Parents struggled to care for children kept at home by the pandemic while also attending to their jobs.

In a June 2020 survey, the CDC found that 41 percent of respondents said they were struggling with mental health and 11 percent had seriously considered suicide recently. Essential workers, unpaid caregivers , young adults, and members of racial and ethnic minority groups were found to be at a higher risk for experiencing mental health struggles, with 31 percent of unpaid caregivers reporting that they were considering suicide. WHO reported two years later that the pandemic had caused a 25 percent increase in anxiety and depression worldwide, young people and women being at the highest risk.

The rate of homicides by firearm in the United States rose by 35 percent during the pandemic to the highest rate in more than a quarter century.

A silver lining in the chaos of the pandemic’s opening year was the development in just 11 months of highly effective vaccines for the virus, a process that normally had taken 7–10 years. The U.S. government’s bet on unproven messenger RNA technology under the Trump administration’s Operation Warp Speed paid off, and the result validated the billions of dollars that the government pours into basic research every year.

On December 14, 2020, New York nurse Sandra Lindsay capped the tumultuous year by receiving the first shot of the vaccine that eventually would help end the public health crisis caused by COVID-19 pandemic.

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.

Effects of COVID-19 pandemic in daily life

Dear Editor,

COVID-19 (Coronavirus) has affected day to day life and is slowing down the global economy. This pandemic has affected thousands of peoples, who are either sick or are being killed due to the spread of this disease. The most common symptoms of this viral infection are fever, cold, cough, bone pain and breathing problems, and ultimately leading to pneumonia. This, being a new viral disease affecting humans for the first time, vaccines are not yet available. Thus, the emphasis is on taking extensive precautions such as extensive hygiene protocol (e.g., regularly washing of hands, avoidance of face to face interaction etc.), social distancing, and wearing of masks, and so on. This virus is spreading exponentially region wise. Countries are banning gatherings of people to the spread and break the exponential curve. 1 , 2 Many countries are locking their population and enforcing strict quarantine to control the spread of the havoc of this highly communicable disease.

COVID-19 has rapidly affected our day to day life, businesses, disrupted the world trade and movements. Identification of the disease at an early stage is vital to control the spread of the virus because it very rapidly spreads from person to person. Most of the countries have slowed down their manufacturing of the products. 3 , 4 The various industries and sectors are affected by the cause of this disease; these include the pharmaceuticals industry, solar power sector, tourism, Information and electronics industry. This virus creates significant knock-on effects on the daily life of citizens, as well as about the global economy.

Presently the impacts of COVID-19 in daily life are extensive and have far reaching consequences. These can be divided into various categories:

  • • Challenges in the diagnosis, quarantine and treatment of suspected or confirmed cases
  • • High burden of the functioning of the existing medical system
  • • Patients with other disease and health problems are getting neglected
  • • Overload on doctors and other healthcare professionals, who are at a very high risk
  • • Overloading of medical shops
  • • Requirement for high protection
  • • Disruption of medical supply chain
  • • Slowing of the manufacturing of essential goods
  • • Disrupt the supply chain of products
  • • Losses in national and international business
  • • Poor cash flow in the market
  • • Significant slowing down in the revenue growth
  • • Service sector is not being able to provide their proper service
  • • Cancellation or postponement of large-scale sports and tournaments
  • • Avoiding the national and international travelling and cancellation of services
  • • Disruption of celebration of cultural, religious and festive events
  • • Undue stress among the population
  • • Social distancing with our peers and family members
  • • Closure of the hotels, restaurants and religious places
  • • Closure of places for entertainment such as movie and play theatres, sports clubs, gymnasiums, swimming pools, and so on.
  • • Postponement of examinations

This COVID-19 has affected the sources of supply and effects the global economy. There are restrictions of travelling from one country to another country. During travelling, numbers of cases are identified positive when tested, especially when they are taking international visits. 5 All governments, health organisations and other authorities are continuously focussing on identifying the cases affected by the COVID-19. Healthcare professional face lot of difficulties in maintaining the quality of healthcare in these days.

Metrics details

Navigating the rapidly growing body of scientific literature on the SARS-CoV-2 pandemic is challenging, and ongoing critical appraisal of this output is essential. We aimed to summarize and critically appraise systematic reviews of coronavirus disease (COVID-19) in humans that were available at the beginning of the pandemic.

Nine databases (Medline, EMBASE, Cochrane Library, CINAHL, Web of Sciences, PDQ-Evidence, WHO’s Global Research, LILACS, and Epistemonikos) were searched from December 1, 2019, to March 24, 2020. Systematic reviews analyzing primary studies of COVID-19 were included. Two authors independently undertook screening, selection, extraction (data on clinical symptoms, prevalence, pharmacological and non-pharmacological interventions, diagnostic test assessment, laboratory, and radiological findings), and quality assessment (AMSTAR 2). A meta-analysis was performed of the prevalence of clinical outcomes.

Eighteen systematic reviews were included; one was empty (did not identify any relevant study). Using AMSTAR 2, confidence in the results of all 18 reviews was rated as “critically low”. Identified symptoms of COVID-19 were (range values of point estimates): fever (82–95%), cough with or without sputum (58–72%), dyspnea (26–59%), myalgia or muscle fatigue (29–51%), sore throat (10–13%), headache (8–12%) and gastrointestinal complaints (5–9%). Severe symptoms were more common in men. Elevated C-reactive protein and lactate dehydrogenase, and slightly elevated aspartate and alanine aminotransferase, were commonly described. Thrombocytopenia and elevated levels of procalcitonin and cardiac troponin I were associated with severe disease. A frequent finding on chest imaging was uni- or bilateral multilobar ground-glass opacity. A single review investigated the impact of medication (chloroquine) but found no verifiable clinical data. All-cause mortality ranged from 0.3 to 13.9%.

Conclusions

In this overview of systematic reviews, we analyzed evidence from the first 18 systematic reviews that were published after the emergence of COVID-19. However, confidence in the results of all reviews was “critically low”. Thus, systematic reviews that were published early on in the pandemic were of questionable usefulness. Even during public health emergencies, studies and systematic reviews should adhere to established methodological standards.

Peer Review reports

The spread of the “Severe Acute Respiratory Coronavirus 2” (SARS-CoV-2), the causal agent of COVID-19, was characterized as a pandemic by the World Health Organization (WHO) in March 2020 and has triggered an international public health emergency [ 1 ]. The numbers of confirmed cases and deaths due to COVID-19 are rapidly escalating, counting in millions [ 2 ], causing massive economic strain, and escalating healthcare and public health expenses [ 3 , 4 ].

The research community has responded by publishing an impressive number of scientific reports related to COVID-19. The world was alerted to the new disease at the beginning of 2020 [ 1 ], and by mid-March 2020, more than 2000 articles had been published on COVID-19 in scholarly journals, with 25% of them containing original data [ 5 ]. The living map of COVID-19 evidence, curated by the Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-Centre), contained more than 40,000 records by February 2021 [ 6 ]. More than 100,000 records on PubMed were labeled as “SARS-CoV-2 literature, sequence, and clinical content” by February 2021 [ 7 ].

Due to publication speed, the research community has voiced concerns regarding the quality and reproducibility of evidence produced during the COVID-19 pandemic, warning of the potential damaging approach of “publish first, retract later” [ 8 ]. It appears that these concerns are not unfounded, as it has been reported that COVID-19 articles were overrepresented in the pool of retracted articles in 2020 [ 9 ]. These concerns about inadequate evidence are of major importance because they can lead to poor clinical practice and inappropriate policies [ 10 ].

Systematic reviews are a cornerstone of today’s evidence-informed decision-making. By synthesizing all relevant evidence regarding a particular topic, systematic reviews reflect the current scientific knowledge. Systematic reviews are considered to be at the highest level in the hierarchy of evidence and should be used to make informed decisions. However, with high numbers of systematic reviews of different scope and methodological quality being published, overviews of multiple systematic reviews that assess their methodological quality are essential [ 11 , 12 , 13 ]. An overview of systematic reviews helps identify and organize the literature and highlights areas of priority in decision-making.

In this overview of systematic reviews, we aimed to summarize and critically appraise systematic reviews of coronavirus disease (COVID-19) in humans that were available at the beginning of the pandemic.

Methodology

Research question.

This overview’s primary objective was to summarize and critically appraise systematic reviews that assessed any type of primary clinical data from patients infected with SARS-CoV-2. Our research question was purposefully broad because we wanted to analyze as many systematic reviews as possible that were available early following the COVID-19 outbreak.

Study design

We conducted an overview of systematic reviews. The idea for this overview originated in a protocol for a systematic review submitted to PROSPERO (CRD42020170623), which indicated a plan to conduct an overview.

Overviews of systematic reviews use explicit and systematic methods for searching and identifying multiple systematic reviews addressing related research questions in the same field to extract and analyze evidence across important outcomes. Overviews of systematic reviews are in principle similar to systematic reviews of interventions, but the unit of analysis is a systematic review [ 14 , 15 , 16 ].

We used the overview methodology instead of other evidence synthesis methods to allow us to collate and appraise multiple systematic reviews on this topic, and to extract and analyze their results across relevant topics [ 17 ]. The overview and meta-analysis of systematic reviews allowed us to investigate the methodological quality of included studies, summarize results, and identify specific areas of available or limited evidence, thereby strengthening the current understanding of this novel disease and guiding future research [ 13 ].

A reporting guideline for overviews of reviews is currently under development, i.e., Preferred Reporting Items for Overviews of Reviews (PRIOR) [ 18 ]. As the PRIOR checklist is still not published, this study was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 statement [ 19 ]. The methodology used in this review was adapted from the Cochrane Handbook for Systematic Reviews of Interventions and also followed established methodological considerations for analyzing existing systematic reviews [ 14 ].

Approval of a research ethics committee was not necessary as the study analyzed only publicly available articles.

Eligibility criteria

Systematic reviews were included if they analyzed primary data from patients infected with SARS-CoV-2 as confirmed by RT-PCR or another pre-specified diagnostic technique. Eligible reviews covered all topics related to COVID-19 including, but not limited to, those that reported clinical symptoms, diagnostic methods, therapeutic interventions, laboratory findings, or radiological results. Both full manuscripts and abbreviated versions, such as letters, were eligible.

No restrictions were imposed on the design of the primary studies included within the systematic reviews, the last search date, whether the review included meta-analyses or language. Reviews related to SARS-CoV-2 and other coronaviruses were eligible, but from those reviews, we analyzed only data related to SARS-CoV-2.

No consensus definition exists for a systematic review [ 20 ], and debates continue about the defining characteristics of a systematic review [ 21 ]. Cochrane’s guidance for overviews of reviews recommends setting pre-established criteria for making decisions around inclusion [ 14 ]. That is supported by a recent scoping review about guidance for overviews of systematic reviews [ 22 ].

Thus, for this study, we defined a systematic review as a research report which searched for primary research studies on a specific topic using an explicit search strategy, had a detailed description of the methods with explicit inclusion criteria provided, and provided a summary of the included studies either in narrative or quantitative format (such as a meta-analysis). Cochrane and non-Cochrane systematic reviews were considered eligible for inclusion, with or without meta-analysis, and regardless of the study design, language restriction and methodology of the included primary studies. To be eligible for inclusion, reviews had to be clearly analyzing data related to SARS-CoV-2 (associated or not with other viruses). We excluded narrative reviews without those characteristics as these are less likely to be replicable and are more prone to bias.

Scoping reviews and rapid reviews were eligible for inclusion in this overview if they met our pre-defined inclusion criteria noted above. We included reviews that addressed SARS-CoV-2 and other coronaviruses if they reported separate data regarding SARS-CoV-2.

Information sources

Nine databases were searched for eligible records published between December 1, 2019, and March 24, 2020: Cochrane Database of Systematic Reviews via Cochrane Library, PubMed, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Web of Sciences, LILACS (Latin American and Caribbean Health Sciences Literature), PDQ-Evidence, WHO’s Global Research on Coronavirus Disease (COVID-19), and Epistemonikos.

The comprehensive search strategy for each database is provided in Additional file 1 and was designed and conducted in collaboration with an information specialist. All retrieved records were primarily processed in EndNote, where duplicates were removed, and records were then imported into the Covidence platform [ 23 ]. In addition to database searches, we screened reference lists of reviews included after screening records retrieved via databases.

Study selection

All searches, screening of titles and abstracts, and record selection, were performed independently by two investigators using the Covidence platform [ 23 ]. Articles deemed potentially eligible were retrieved for full-text screening carried out independently by two investigators. Discrepancies at all stages were resolved by consensus. During the screening, records published in languages other than English were translated by a native/fluent speaker.

Data collection process

We custom designed a data extraction table for this study, which was piloted by two authors independently. Data extraction was performed independently by two authors. Conflicts were resolved by consensus or by consulting a third researcher.

We extracted the following data: article identification data (authors’ name and journal of publication), search period, number of databases searched, population or settings considered, main results and outcomes observed, and number of participants. From Web of Science (Clarivate Analytics, Philadelphia, PA, USA), we extracted journal rank (quartile) and Journal Impact Factor (JIF).

We categorized the following as primary outcomes: all-cause mortality, need for and length of mechanical ventilation, length of hospitalization (in days), admission to intensive care unit (yes/no), and length of stay in the intensive care unit.

The following outcomes were categorized as exploratory: diagnostic methods used for detection of the virus, male to female ratio, clinical symptoms, pharmacological and non-pharmacological interventions, laboratory findings (full blood count, liver enzymes, C-reactive protein, d-dimer, albumin, lipid profile, serum electrolytes, blood vitamin levels, glucose levels, and any other important biomarkers), and radiological findings (using radiography, computed tomography, magnetic resonance imaging or ultrasound).

We also collected data on reporting guidelines and requirements for the publication of systematic reviews and meta-analyses from journal websites where included reviews were published.

Quality assessment in individual reviews

Two researchers independently assessed the reviews’ quality using the “A MeaSurement Tool to Assess Systematic Reviews 2 (AMSTAR 2)”. We acknowledge that the AMSTAR 2 was created as “a critical appraisal tool for systematic reviews that include randomized or non-randomized studies of healthcare interventions, or both” [ 24 ]. However, since AMSTAR 2 was designed for systematic reviews of intervention trials, and we included additional types of systematic reviews, we adjusted some AMSTAR 2 ratings and reported these in Additional file 2 .

Adherence to each item was rated as follows: yes, partial yes, no, or not applicable (such as when a meta-analysis was not conducted). The overall confidence in the results of the review is rated as “critically low”, “low”, “moderate” or “high”, according to the AMSTAR 2 guidance based on seven critical domains, which are items 2, 4, 7, 9, 11, 13, 15 as defined by AMSTAR 2 authors [ 24 ]. We reported our adherence ratings for transparency of our decision with accompanying explanations, for each item, in each included review.

One of the included systematic reviews was conducted by some members of this author team [ 25 ]. This review was initially assessed independently by two authors who were not co-authors of that review to prevent the risk of bias in assessing this study.

Synthesis of results

For data synthesis, we prepared a table summarizing each systematic review. Graphs illustrating the mortality rate and clinical symptoms were created. We then prepared a narrative summary of the methods, findings, study strengths, and limitations.

For analysis of the prevalence of clinical outcomes, we extracted data on the number of events and the total number of patients to perform proportional meta-analysis using RStudio© software, with the “meta” package (version 4.9–6), using the “metaprop” function for reviews that did not perform a meta-analysis, excluding case studies because of the absence of variance. For reviews that did not perform a meta-analysis, we presented pooled results of proportions with their respective confidence intervals (95%) by the inverse variance method with a random-effects model, using the DerSimonian-Laird estimator for τ 2 . We adjusted data using Freeman-Tukey double arcosen transformation. Confidence intervals were calculated using the Clopper-Pearson method for individual studies. We created forest plots using the RStudio© software, with the “metafor” package (version 2.1–0) and “forest” function.

Managing overlapping systematic reviews

Some of the included systematic reviews that address the same or similar research questions may include the same primary studies in overviews. Including such overlapping reviews may introduce bias when outcome data from the same primary study are included in the analyses of an overview multiple times. Thus, in summaries of evidence, multiple-counting of the same outcome data will give data from some primary studies too much influence [ 14 ]. In this overview, we did not exclude overlapping systematic reviews because, according to Cochrane’s guidance, it may be appropriate to include all relevant reviews’ results if the purpose of the overview is to present and describe the current body of evidence on a topic [ 14 ]. To avoid any bias in summary estimates associated with overlapping reviews, we generated forest plots showing data from individual systematic reviews, but the results were not pooled because some primary studies were included in multiple reviews.

Our search retrieved 1063 publications, of which 175 were duplicates. Most publications were excluded after the title and abstract analysis ( n = 860). Among the 28 studies selected for full-text screening, 10 were excluded for the reasons described in Additional file 3 , and 18 were included in the final analysis (Fig. 1 ) [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. Reference list screening did not retrieve any additional systematic reviews.

Characteristics of included reviews

Summary features of 18 systematic reviews are presented in Table 1 . They were published in 14 different journals. Only four of these journals had specific requirements for systematic reviews (with or without meta-analysis): European Journal of Internal Medicine, Journal of Clinical Medicine, Ultrasound in Obstetrics and Gynecology, and Clinical Research in Cardiology . Two journals reported that they published only invited reviews ( Journal of Medical Virology and Clinica Chimica Acta ). Three systematic reviews in our study were published as letters; one was labeled as a scoping review and another as a rapid review (Table 2 ).

All reviews were published in English, in first quartile (Q1) journals, with JIF ranging from 1.692 to 6.062. One review was empty, meaning that its search did not identify any relevant studies; i.e., no primary studies were included [ 36 ]. The remaining 17 reviews included 269 unique studies; the majority ( N = 211; 78%) were included in only a single review included in our study (range: 1 to 12). Primary studies included in the reviews were published between December 2019 and March 18, 2020, and comprised case reports, case series, cohorts, and other observational studies. We found only one review that included randomized clinical trials [ 38 ]. In the included reviews, systematic literature searches were performed from 2019 (entire year) up to March 9, 2020. Ten systematic reviews included meta-analyses. The list of primary studies found in the included systematic reviews is shown in Additional file 4 , as well as the number of reviews in which each primary study was included.

Population and study designs

Most of the reviews analyzed data from patients with COVID-19 who developed pneumonia, acute respiratory distress syndrome (ARDS), or any other correlated complication. One review aimed to evaluate the effectiveness of using surgical masks on preventing transmission of the virus [ 36 ], one review was focused on pediatric patients [ 34 ], and one review investigated COVID-19 in pregnant women [ 37 ]. Most reviews assessed clinical symptoms, laboratory findings, or radiological results.

Systematic review findings

The summary of findings from individual reviews is shown in Table 2 . Overall, all-cause mortality ranged from 0.3 to 13.9% (Fig. 2 ).

A meta-analysis of the prevalence of mortality

Clinical symptoms

Seven reviews described the main clinical manifestations of COVID-19 [ 26 , 28 , 29 , 34 , 35 , 39 , 41 ]. Three of them provided only a narrative discussion of symptoms [ 26 , 34 , 35 ]. In the reviews that performed a statistical analysis of the incidence of different clinical symptoms, symptoms in patients with COVID-19 were (range values of point estimates): fever (82–95%), cough with or without sputum (58–72%), dyspnea (26–59%), myalgia or muscle fatigue (29–51%), sore throat (10–13%), headache (8–12%), gastrointestinal disorders, such as diarrhea, nausea or vomiting (5.0–9.0%), and others (including, in one study only: dizziness 12.1%) (Figs. 3 , 4 , 5 , 6 , 7 , 8 and 9 ). Three reviews assessed cough with and without sputum together; only one review assessed sputum production itself (28.5%).

Diagnostic aspects

Three reviews described methodologies, protocols, and tools used for establishing the diagnosis of COVID-19 [ 26 , 34 , 38 ]. The use of respiratory swabs (nasal or pharyngeal) or blood specimens to assess the presence of SARS-CoV-2 nucleic acid using RT-PCR assays was the most commonly used diagnostic method mentioned in the included studies. These diagnostic tests have been widely used, but their precise sensitivity and specificity remain unknown. One review included a Chinese study with clinical diagnosis with no confirmation of SARS-CoV-2 infection (patients were diagnosed with COVID-19 if they presented with at least two symptoms suggestive of COVID-19, together with laboratory and chest radiography abnormalities) [ 34 ].

Therapeutic possibilities

Pharmacological and non-pharmacological interventions (supportive therapies) used in treating patients with COVID-19 were reported in five reviews [ 25 , 27 , 34 , 35 , 38 ]. Antivirals used empirically for COVID-19 treatment were reported in seven reviews [ 25 , 27 , 34 , 35 , 37 , 38 , 41 ]; most commonly used were protease inhibitors (lopinavir, ritonavir, darunavir), nucleoside reverse transcriptase inhibitor (tenofovir), nucleotide analogs (remdesivir, galidesivir, ganciclovir), and neuraminidase inhibitors (oseltamivir). Umifenovir, a membrane fusion inhibitor, was investigated in two studies [ 25 , 35 ]. Possible supportive interventions analyzed were different types of oxygen supplementation and breathing support (invasive or non-invasive ventilation) [ 25 ]. The use of antibiotics, both empirically and to treat secondary pneumonia, was reported in six studies [ 25 , 26 , 27 , 34 , 35 , 38 ]. One review specifically assessed evidence on the efficacy and safety of the anti-malaria drug chloroquine [ 27 ]. It identified 23 ongoing trials investigating the potential of chloroquine as a therapeutic option for COVID-19, but no verifiable clinical outcomes data. The use of mesenchymal stem cells, antifungals, and glucocorticoids were described in four reviews [ 25 , 34 , 35 , 38 ].

Laboratory and radiological findings

Of the 18 reviews included in this overview, eight analyzed laboratory parameters in patients with COVID-19 [ 25 , 29 , 30 , 32 , 33 , 34 , 35 , 39 ]; elevated C-reactive protein levels, associated with lymphocytopenia, elevated lactate dehydrogenase, as well as slightly elevated aspartate and alanine aminotransferase (AST, ALT) were commonly described in those eight reviews. Lippi et al. assessed cardiac troponin I (cTnI) [ 25 ], procalcitonin [ 32 ], and platelet count [ 33 ] in COVID-19 patients. Elevated levels of procalcitonin [ 32 ] and cTnI [ 30 ] were more likely to be associated with a severe disease course (requiring intensive care unit admission and intubation). Furthermore, thrombocytopenia was frequently observed in patients with complicated COVID-19 infections [ 33 ].

Chest imaging (chest radiography and/or computed tomography) features were assessed in six reviews, all of which described a frequent pattern of local or bilateral multilobar ground-glass opacity [ 25 , 34 , 35 , 39 , 40 , 41 ]. Those six reviews showed that septal thickening, bronchiectasis, pleural and cardiac effusions, halo signs, and pneumothorax were observed in patients suffering from COVID-19.

Quality of evidence in individual systematic reviews

Table 3 shows the detailed results of the quality assessment of 18 systematic reviews, including the assessment of individual items and summary assessment. A detailed explanation for each decision in each review is available in Additional file 5 .

Using AMSTAR 2 criteria, confidence in the results of all 18 reviews was rated as “critically low” (Table 3 ). Common methodological drawbacks were: omission of prospective protocol submission or publication; use of inappropriate search strategy: lack of independent and dual literature screening and data-extraction (or methodology unclear); absence of an explanation for heterogeneity among the studies included; lack of reasons for study exclusion (or rationale unclear).

Risk of bias assessment, based on a reported methodological tool, and quality of evidence appraisal, in line with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method, were reported only in one review [ 25 ]. Five reviews presented a table summarizing bias, using various risk of bias tools [ 25 , 29 , 39 , 40 , 41 ]. One review analyzed “study quality” [ 37 ]. One review mentioned the risk of bias assessment in the methodology but did not provide any related analysis [ 28 ].

This overview of systematic reviews analyzed the first 18 systematic reviews published after the onset of the COVID-19 pandemic, up to March 24, 2020, with primary studies involving more than 60,000 patients. Using AMSTAR-2, we judged that our confidence in all those reviews was “critically low”. Ten reviews included meta-analyses. The reviews presented data on clinical manifestations, laboratory and radiological findings, and interventions. We found no systematic reviews on the utility of diagnostic tests.

Symptoms were reported in seven reviews; most of the patients had a fever, cough, dyspnea, myalgia or muscle fatigue, and gastrointestinal disorders such as diarrhea, nausea, or vomiting. Olfactory dysfunction (anosmia or dysosmia) has been described in patients infected with COVID-19 [ 43 ]; however, this was not reported in any of the reviews included in this overview. During the SARS outbreak in 2002, there were reports of impairment of the sense of smell associated with the disease [ 44 , 45 ].

The reported mortality rates ranged from 0.3 to 14% in the included reviews. Mortality estimates are influenced by the transmissibility rate (basic reproduction number), availability of diagnostic tools, notification policies, asymptomatic presentations of the disease, resources for disease prevention and control, and treatment facilities; variability in the mortality rate fits the pattern of emerging infectious diseases [ 46 ]. Furthermore, the reported cases did not consider asymptomatic cases, mild cases where individuals have not sought medical treatment, and the fact that many countries had limited access to diagnostic tests or have implemented testing policies later than the others. Considering the lack of reviews assessing diagnostic testing (sensitivity, specificity, and predictive values of RT-PCT or immunoglobulin tests), and the preponderance of studies that assessed only symptomatic individuals, considerable imprecision around the calculated mortality rates existed in the early stage of the COVID-19 pandemic.

Few reviews included treatment data. Those reviews described studies considered to be at a very low level of evidence: usually small, retrospective studies with very heterogeneous populations. Seven reviews analyzed laboratory parameters; those reviews could have been useful for clinicians who attend patients suspected of COVID-19 in emergency services worldwide, such as assessing which patients need to be reassessed more frequently.

All systematic reviews scored poorly on the AMSTAR 2 critical appraisal tool for systematic reviews. Most of the original studies included in the reviews were case series and case reports, impacting the quality of evidence. Such evidence has major implications for clinical practice and the use of these reviews in evidence-based practice and policy. Clinicians, patients, and policymakers can only have the highest confidence in systematic review findings if high-quality systematic review methodologies are employed. The urgent need for information during a pandemic does not justify poor quality reporting.

We acknowledge that there are numerous challenges associated with analyzing COVID-19 data during a pandemic [ 47 ]. High-quality evidence syntheses are needed for decision-making, but each type of evidence syntheses is associated with its inherent challenges.

The creation of classic systematic reviews requires considerable time and effort; with massive research output, they quickly become outdated, and preparing updated versions also requires considerable time. A recent study showed that updates of non-Cochrane systematic reviews are published a median of 5 years after the publication of the previous version [ 48 ].

Authors may register a review and then abandon it [ 49 ], but the existence of a public record that is not updated may lead other authors to believe that the review is still ongoing. A quarter of Cochrane review protocols remains unpublished as completed systematic reviews 8 years after protocol publication [ 50 ].

Rapid reviews can be used to summarize the evidence, but they involve methodological sacrifices and simplifications to produce information promptly, with inconsistent methodological approaches [ 51 ]. However, rapid reviews are justified in times of public health emergencies, and even Cochrane has resorted to publishing rapid reviews in response to the COVID-19 crisis [ 52 ]. Rapid reviews were eligible for inclusion in this overview, but only one of the 18 reviews included in this study was labeled as a rapid review.

Ideally, COVID-19 evidence would be continually summarized in a series of high-quality living systematic reviews, types of evidence synthesis defined as “ a systematic review which is continually updated, incorporating relevant new evidence as it becomes available ” [ 53 ]. However, conducting living systematic reviews requires considerable resources, calling into question the sustainability of such evidence synthesis over long periods [ 54 ].

Research reports about COVID-19 will contribute to research waste if they are poorly designed, poorly reported, or simply not necessary. In principle, systematic reviews should help reduce research waste as they usually provide recommendations for further research that is needed or may advise that sufficient evidence exists on a particular topic [ 55 ]. However, systematic reviews can also contribute to growing research waste when they are not needed, or poorly conducted and reported. Our present study clearly shows that most of the systematic reviews that were published early on in the COVID-19 pandemic could be categorized as research waste, as our confidence in their results is critically low.

Our study has some limitations. One is that for AMSTAR 2 assessment we relied on information available in publications; we did not attempt to contact study authors for clarifications or additional data. In three reviews, the methodological quality appraisal was challenging because they were published as letters, or labeled as rapid communications. As a result, various details about their review process were not included, leading to AMSTAR 2 questions being answered as “not reported”, resulting in low confidence scores. Full manuscripts might have provided additional information that could have led to higher confidence in the results. In other words, low scores could reflect incomplete reporting, not necessarily low-quality review methods. To make their review available more rapidly and more concisely, the authors may have omitted methodological details. A general issue during a crisis is that speed and completeness must be balanced. However, maintaining high standards requires proper resourcing and commitment to ensure that the users of systematic reviews can have high confidence in the results.

Furthermore, we used adjusted AMSTAR 2 scoring, as the tool was designed for critical appraisal of reviews of interventions. Some reviews may have received lower scores than actually warranted in spite of these adjustments.

Another limitation of our study may be the inclusion of multiple overlapping reviews, as some included reviews included the same primary studies. According to the Cochrane Handbook, including overlapping reviews may be appropriate when the review’s aim is “ to present and describe the current body of systematic review evidence on a topic ” [ 12 ], which was our aim. To avoid bias with summarizing evidence from overlapping reviews, we presented the forest plots without summary estimates. The forest plots serve to inform readers about the effect sizes for outcomes that were reported in each review.

Several authors from this study have contributed to one of the reviews identified [ 25 ]. To reduce the risk of any bias, two authors who did not co-author the review in question initially assessed its quality and limitations.

Finally, we note that the systematic reviews included in our overview may have had issues that our analysis did not identify because we did not analyze their primary studies to verify the accuracy of the data and information they presented. We give two examples to substantiate this possibility. Lovato et al. wrote a commentary on the review of Sun et al. [ 41 ], in which they criticized the authors’ conclusion that sore throat is rare in COVID-19 patients [ 56 ]. Lovato et al. highlighted that multiple studies included in Sun et al. did not accurately describe participants’ clinical presentations, warning that only three studies clearly reported data on sore throat [ 56 ].

In another example, Leung [ 57 ] warned about the review of Li, L.Q. et al. [ 29 ]: “ it is possible that this statistic was computed using overlapped samples, therefore some patients were double counted ”. Li et al. responded to Leung that it is uncertain whether the data overlapped, as they used data from published articles and did not have access to the original data; they also reported that they requested original data and that they plan to re-do their analyses once they receive them; they also urged readers to treat the data with caution [ 58 ]. This points to the evolving nature of evidence during a crisis.

Our study’s strength is that this overview adds to the current knowledge by providing a comprehensive summary of all the evidence synthesis about COVID-19 available early after the onset of the pandemic. This overview followed strict methodological criteria, including a comprehensive and sensitive search strategy and a standard tool for methodological appraisal of systematic reviews.

In conclusion, in this overview of systematic reviews, we analyzed evidence from the first 18 systematic reviews that were published after the emergence of COVID-19. However, confidence in the results of all the reviews was “critically low”. Thus, systematic reviews that were published early on in the pandemic could be categorized as research waste. Even during public health emergencies, studies and systematic reviews should adhere to established methodological standards to provide patients, clinicians, and decision-makers trustworthy evidence.

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.

11.1

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.

11.2

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.

Experts Call for “Reimagining” Public Health in the United States

Ross Brownson

The public health system in the United States needs an immediate “transformation,” two of the nation’s leading health experts write in a new appeal for change driven by the COVID-19 pandemic, climate change, and the politicization of public health.

The essay is the lead article in “Reimagining Public Health,” a new  special issue  of  Health Affairs , one of the nation’s foremost health policy journals. The authors are Ross C. Brownson , the Steven H. and Susan U. Lipstein Distinguished Professor at the Brown School and founder of the Prevention Research Center ; and Jonathan Samet , a professor and the former dean of the Colorado School of Public Health.

“No matter what label we attach to this effort, the past several years have made one thing clear: Transformation of the US public health system is needed, and needed now,” the authors conclude in their essay,  “Reimagining Public Health: Mapping a Path Forward.”   Brownson and Samet were co-authors four years ago of a missive in the  American Journal of Public Health  that called for public health change as the nation grappled with the pandemic. The current version builds on their thinking and provides more specifics, said Brownson, who hosted a  podcast  on the subject.

“COVID demonstrated not only the value of public health, but also how it has been politicized, and the need for focused change,” he said. He and Samet talked with nine public health leaders about their ideas on the path forward.  Brownson said they were encouraged by the positive views of those leaders, even in states where criticism of public health has been substantial.  “One of the things we found inspiring was how optimistic they are,” he said. “That gave us reassurance this thing can be done with focused effort, political will, leadership, and funding incentives.”

In their essay, Brownson and Samet note that the decentralized public health system in the U.S. is administrated and distributed across approximately 3,000 state and local health departments, encompassing governmental public health; community-based organizations; the health care sector; and the education, training, and research of academic public health and medical enterprises. While that far-flung group offers opportunities for using local data in policy and practice, it also can result in an uneven allocation of resources and decision-making.

Public-health experts had been calling for a revamping of the American system even before COVID, but the pandemic “laid bare the deficiencies of the existing public health system and heightened the politicization of public health along partisan lines to an unworkable level in some jurisdictions,” the authors wrote, and highlighted the need for global collaboration.

The essay makes recommendations in seven areas of focus to guide public health transformation:

  • Accountability:  Provide as much transparency as possible in government actions, and share decisionmaking, budgeting and communication with community members.
  • Politicization and polarization:  Identify areas where there is consensus/common ground, make better use of local data and messengers, and establish legal protections from violence against public health workers.
  • Climate change:  Make climate change a core priority, develop ways to track its effects, and advocate for policies to address the root causes.
  • Equity:  Make health equity a core value of public health agencies, build skills among staff, fully engage the public and policymakers and address health and social needs in marginalized populations.
  • Data sciences:  Support the harmonization of data sets and repositories, enhance capacity, engage communities and develop real-time surveillance system to detect and monitor threats to public health.
  • Workforce:  Develop training in new areas, including resilience, communication, systems thinking and entrepreneurship.
  • Communication:   Identify distinct audiences, create messages that are positive and show benefits, translate evidence into easily understood stories, and identify “superspreaders” of misinformation.
