Once again, the coronavirus is ascendant. As infections mount across the country, it is dawning on Americans that the epidemic is now unstoppable, and that no corner of the nation will be left untouched.
As of Tuesday, the pathogen had infected at least 4.3 million Americans, killing almost 150,000. Many experts fear the virus could kill 200,000 or even 300,000 by year’s end. Even President Trump has donned a mask, after resisting for months, and has canceled the Republican National Convention celebrations in Florida.
Each state, each city has its own crisis driven by its own risk factors: vacation crowds in one, bars reopened too soon in another, a revolt against masks in a third.
“We are in a worse place than we were in March,” when the virus coursed through New York, said Dr. Leana S. Wen, a former Baltimore health commissioner. “Back then we had one epicenter. Now we have lots.
To assess where the country is heading now, The New York Times interviewed 20 public health experts — not just clinicians and epidemiologists, but also historians and sociologists, because the spread of the virus is now influenced as much by human behavior as it is by the pathogen itself.
Not only are American cities in the South and West facing deadly outbreaks like those that struck Northeastern cities in the spring, but rural areas are being hurt, too. In every region, people of color will continue to suffer disproportionately, experts said.
While there may be no appetite for a national lockdown, local restrictions must be tightened when required, the researchers said, and governors and mayors must have identical goals. Testing must become more targeted.
In most states, contact tracing is now moot — there are simply too many cases to track. And while progress has been made on vaccines, none is expected to arrive this winter in time to stave off what many fear will be a new wave of deaths.
Overall, the scientists conveyed a pervasive sense of sadness and exhaustion. Where once there was defiance, and then a growing sense of dread, now there seems to be sorrow and frustration, a feeling that so many funerals never had to happen and that nothing is going well. The United States is a wounded giant, while much of Europe, which was hit first, is recovering and reopening — although not to us.
“We’re all incredibly depressed and in shock at how out of control the virus is in the U.S.,” said Dr. Michele Barry, the director of the Center for Innovation in Global Health at Stanford University.
With so much wealth and medical talent, they asked, how could we have done so poorly? How did we fare not just worse than autocratic China and isolated New Zealand, but also worse than tiny, much poorer nations like Vietnam and Rwanda?
“National hubris and belief in American exceptionalism have served us badly,” said Martha L. Lincoln, a medical anthropologist and historian at San Francisco State University. “We were not prepared to see the risk of failure.”
Since the coronavirus was first found to be the cause of lethal pneumonias in Wuhan, China, in late 2019, scientists have gained a better understanding of the enemy.
It is extremely transmissible, through not just coughed droplets but also a fine aerosol mist that is expelled when people talk loudly, laugh or sing and that can linger in indoor air. As a result, masks are far more effective than scientists once believed.
The infection may start in the lungs, but it is very different from influenza, a respiratory virus. In severely ill patients, the coronavirus may attach to receptors inside the veins and arteries, and move on to attack the kidneys, the heart, the gut and even the brain, choking off these organs with hundreds of tiny blood clots.
Most of the virus’s victims are elderly, but it has not spared young adults, especially those with obesity, high blood pressure or diabetes. Adults aged 18 to 49 now account for more hospitalized cases than people aged 50 to 64 or those 65 and older.
Children are usually not harmed by the virus, although clinicians were dismayed to discover a few who were struck by a rare but dangerous inflammatory version. Young children appear to transmit the virus less often than teenagers, which may affect how schools can be opened.
Among adults, a very different picture has emerged. Growing evidence suggests that perhaps 10 percent of the infected account for 80 percent of new transmissions. Unpredictable superspreading events in nursing homes, meatpacking plants, churches, prisons and bars are major drivers of the epidemic.
Thus far, none of the medicines for which hopes were once high — repurposed malaria drugs, AIDS drugs and antivirals — have proved to be rapid cures. One antiviral, remdesivir, has been shown to shorten hospital stays, while a common steroid, dexamethasone, has helped save some severely ill patients.One or even several vaccines may be available by year’s end, which would be a spectacular achievement. But by then the virus may have in its grip virtually every village and city on the globe.
Some experts, like Michael T. Osterholm, the director of the University of Minnesota’s Center for Infectious Disease Research and Policy, argue that only a nationwide lockdown can completely contain the virus now. Other researchers think that is politically impossible, but emphasize that localities must be free to act quickly and enforce strong measures with support from their state capitols.
Danielle Allen, the director of Harvard University’s Edmond J. Safra Center for Ethics, which has issued pandemic response plans, said that finding less than one case per 100,000 people means a community should continue testing, contact tracing and isolating cases — with financial support for those who need it.
Up to 25 cases per 100,000 requires greater restrictions, like closing bars and limiting gatherings. Above that number, authorities should issue stay-at-home orders, she said.
Testing must be focused, not just offered at convenient parking lots, experts said, and it should be most intense in institutions like nursing homes, prisons, factories or other places at risk of superspreading events.
Testing must be free in places where people are poor or uninsured, such as public housing projects, Native American reservations and churches and grocery stores in impoverished neighborhoods.
None of this will be possible unless the nation’s capacity for testing, a continuing disaster, is greatly expanded. By the end of summer, the administration hopes to start using “pooling,” in which tests are combined in batches to speed up the process.
But the method only works in communities with lower infection rates, where large numbers of pooled tests turn up relatively few positive results. It fails where the virus has spread everywhere, because too many batches turn up positive results that require retesting.
At the moment, the United States tests roughly 800,000 people per day, about 38 percent of the number some experts think is needed.
Above all, researchers said, mask use should be universal indoors — including airplanes, subway cars and every other enclosed space — and outdoors anywhere people are less than six feet apart.
Dr. Emily Landon, an infection control specialist at the University of Chicago Pritzker School of Medicine, said it was “sad that something as simple as a mask got politicized.”
“It’s not a statement, it’s a piece of clothing,” she added. “You get used to it the way you got used to wearing pants.”
Arguments that masks infringe on personal rights must be countered both by legal orders and by persuasion. “We need more credible messengers endorsing masks,” Dr. Wen said — just before the president himself became a messenger.
“They could include C.E.O.s or celebrities or religious leaders. Different people are influencers to different demographics.”
Although this feels like a new debate, it is actually an old one. Masks were common in some Western cities during the 1918 flu pandemic and mandatory in San Francisco. There was even a jingle: “Obey the laws, wear the gauze. Protect your jaws from septic paws.”
“A libertarian movement, the Anti-Mask League, emerged,” Dr. Lincoln of San Francisco State said. “There were fistfights with police officers over it.” Ultimately, city officials “waffled” and compliance faded.
“I wonder what this issue would be like today,” she mused, “if that hadn’t happened.”
Images of Americans disregarding social distancing requirements have become a daily news staple. But the pictures are deceptive: Americans are more accepting of social distancing than the media sometimes portrays, said Beth Redbird, a Northwestern University sociologist who since March has conducted regular surveys of 8,000 adults about the impact of the virus.
“About 70 percent of Americans report using all forms of it,” she said. “And when we give them adjective choices, they describe people who won’t distance as mean, selfish or unintelligent, not as generous, open-minded or patriotic.”
The key predictor, she said in early July, was whether or not the poll respondent trusted Mr. Trump. Those who trusted him were less likely to practice social distancing. That was true of Republicans and independents, “and there’s no such thing as a Democrat who trusts Donald Trump,” she added.
Whether or not people support coercive measures like stay-at-home orders or bar closures depended on how scared the respondent was.
“When rising case numbers make people more afraid, they have more taste for liberty-constraining actions,” Dr. Redbird said. And no economic recovery will occur, she added, “until people aren’t afraid. If they are, they won’t go out and spend money even if they’re allowed to.”
As of Tuesday, new infections were still rising in 28 states, according to a database maintained by The Times.
Weeks ago, experts like Dr. Anthony S. Fauci, the director of the National Institute for Allergy and Infectious Diseases, were advising states where the virus was surging to pull back from reopening by closing down bars, forbidding large gatherings and requiring mask usage.
Many of those states are finally taking that advice, but it is not yet clear whether this national change of heart has happened in time to stop the newest wave of deaths from ultimately exceeding the 2,750-a-day peak of mid-April. Through Tuesday, the seven-day average was 1,078 virus deaths nationwide.
Deaths may surge even higher, experts warned, when cold weather, rain and snow force Americans to meet indoors, eat indoors and crowd into public transit.
Oddly, states that are now hard-hit might become safer, some experts suggested. In the South and Southwest, summers are so hot that diners seek air-conditioning indoors, but eating outdoors in December can be pleasant.
Several studies have confirmed transmission in air-conditioned rooms. In one well-known case cluster in a restaurant in Guangzhou, China, researchers concluded that air-conditioners blew around a viral cloud, infecting patrons as far as 10 feet from a sick diner.
Rural areas face another risk. Almost 80 percent of the country’s counties lack even one infectious disease specialist, according to a study led by Dr. Rochelle Walensky, the chief of infectious diseases at Massachusetts General Hospital in Boston.
At the moment, the crisis is most acute in Southern and Southwestern states. But websites that track transmission ratesshow that hot spots can turn up anywhere. For three weeks, for example, Alaska’s small outbreak has been one of the country’s fastest-spreading, while transmission in Texas and Arizona has dramatically slowed.
Deaths now may rise more slowly than they did in spring, because hospitalized patients are, on average, younger this time. But overwhelmed hospitals can lead to excess deaths from many causes all over a community, as ambulances are delayed and people having health crises avoid hospitals out of fear.
The experts were divided as to what role influenza will play in the fall. A harsh flu season could flood hospitals with pneumonia patients needing ventilators. But some said the flu season could be mild or almost nonexistent this year.
Normally, the flu virus migrates from the Northern Hemisphere to the Southern Hemisphere in the spring — presumably in air travelers — and then returns in the fall, with new mutations that may make it a poor match for the annual vaccine.
But this year, the national lockdown abruptly ended flu transmission in late April, according to weekly Fluview reportsfrom the Centers for Disease Control and Prevention. International air travel has been sharply curtailed, and there has been almost no flu activity in the whole southern hemisphere this year.
Assuming there is still little air travel to the United States this fall, there may be little “reseeding” of the flu virus here. But in case that prediction turns out be wrong, all the researchers advised getting flu shots anyway.
“There’s no reason to be caught unprepared for two respiratory viruses,” said Tara C. Smith, an epidemiologist at Kent State University’s School of Public Health.
Experts familiar with vaccine and drug manufacturing were disappointed that, thus far, only dexamethasone and remdesivir have proved to be effective treatments, and then only partially.
Most felt that monoclonal antibodies — cloned human proteins that can be grown in cell culture — represented the best hope until vaccines arrive. Regeneron, Eli Lilly and other drugmakers are working on candidates.
“They’re promising both for treatment and for prophylaxis, and there are companies with track records and manufacturing platforms,” said Dr. Luciana Borio, a former director of medical and biodefense preparedness at the National Security Council. “But manufacturing capacity is limited.”
According to a database compiled by The Times, researchers worldwide are developing more than 165 vaccine candidates, and 27 are in human trials.
New announcements are pouring in, and the pressure to hurry is intense: The Trump administration just awarded nearly $2 billion to a Pfizer-led consortium that promised 100 million doses by December, assuming trials succeed.
Because the virus is still spreading rapidly, most experts said “challenge trials,” in which a small number of volunteers are vaccinated and then deliberately infected, would probably not be needed.
Absent a known cure, “challenges” can be ethically fraught, and some doctors oppose doing them for this virus. “They don’t tell you anything about safety,” Dr. Borio said.
And when a virus is circulating unchecked, a typical placebo-controlled trial with up to 30,000 participants can be done efficiently, she added. Moderna and Pfizer have already begun such trials.
The Food and Drug Administration has said a vaccine will pass muster even if it is only 50 percent effective. Experts said they could accept that, at least initially, because the first vaccine approved could save lives while testing continued on better alternatives.
“A vaccine doesn’t have to work perfectly to be useful,” Dr. Walensky said. “Even with measles vaccine, you can sometimes still get measles — but it’s mild, and you aren’t infectious.”
“We don’t know if a vaccine will work in older folks. We don’t know exactly what level of herd immunity we’ll need to stop the epidemic. But anything safe and fairly effective should help.”
Still, haste is risky, experts warned, especially when opponents of vaccines are spreading fear. If a vaccine is rushed to marketwithout thorough safety testing and recipients are hurt by it, all vaccines could be set back for years.
No matter what state the virus reaches, one risk remains constant. Even in states with few Black and Hispanic residents, they are usually hit hardest, experts said.
People of color are more likely to have jobs that require physical presence and sometimes close contact, such as construction work, store clerking and nursing. They are more likely to rely on public transit and to live in neighborhoods where grocery stores are scarce and crowded.
They are more likely to live in crowded housing and multigenerational homes, some with only one bathroom, making safe home isolation impossible when sickness strikes. They have higher rates of obesity, high blood pressure, diabetes and asthma.
Federal data gathered through May 28 shows that Black and Hispanic Americans were three times as likely to get infected as their white neighbors, and twice as likely to die, even if they lived in remote rural counties with few Black or Hispanic residents.
“By the time that minority patient sets foot in a hospital, he is already on an unequal footing,” said Elaine Hernandez, a sociologist at Indiana University.
The differences persist even though Black and Hispanic adults drastically altered their behavior. One study found that through the beginning of May, the average Black American practiced more social distancing than the average white American.
The top factor making people adopt self-protective behavior is personally knowing someone who fell ill, said Dr. Redbird. By the end of spring, Black and Hispanic Americans were 50 percent more likely than white Americans to know someone who had been ill, her surveys found.
Dr. Hernandez, whose parents live in Arizona, said their neighbors who had not been scared in June had since changed their attitudes.
Her father, a physician, had set an example. Early on, he wore a mask with a silly mustache when he and his wife took walks, and they would decline friends’ invitations, saying, “No, we’re staying in our bubble.”
Now, she said, their neighbors are wearing masks, “and people are telling my father, ‘You were right,’” Dr. Hernandez said.
There was no widespread agreement among experts about what is likely to happen in the years after the pandemic. Some scientists expected a quick economic recovery; others thought the damage could persist for years.
Working at home will become more common, some predicted, while crowded, open-plan offices may be changed. The just-in-time supply chains on which many businesses depend will need fixing because the processes failed to deliver adequate protective gear, ventilators and test materials.
A disease-modeling system like that used by the National Weather Service to predict storms is needed, said Caitlin Rivers, an epidemiologist at the Johns Hopkins Center for Health Security. Right now, the country has surveillance for seasonal flu but no national map tracking all disease outbreaks. As Dr. Thomas R. Frieden, a former C.D.C. director, recently pointed out, states are not even required to track the same data.
Several experts said they assumed that millions of Americans who have been left without health insurance or forced to line up at food banks would vote for politicians favoring universal health care, paid sick leave, greater income equality and other changes.
But given the country’s deep political divisions, no researcher was certain what the outcome of the coming election would be.
Dr. Redbird said her polling of Americans showed “little faith in institutions across the board — we’re not seeing an increase in trust in science or an appetite for universal health care or workers equity.”
The Trump administration did little to earn trust. More than six months into the worst health crisis in a century, Mr. Trump only last week urged Americans to wear masks and canceled the Republican convention in Florida, the kind of high-risk indoor event that states have been banning since mid-March.
“It will probably, unfortunately, get worse before it gets better,” Mr. Trump said at the first of the resurrected coronavirus task force briefings earlier this month, which included no scientists or health officials. The briefings were discontinued in April amid his rosy predications that the epidemic would soon be over.
Mr. Trump has ignored, contradicted or disparaged his scientific advisers, repeatedly saying that the virus simply would go away, touting unproven drugs like hydroxychloroquine even after they were shown to be ineffective and sometimes dangerous, and suggesting that disinfectants or lethal ultraviolet light might be used inside the body.
Millions of Americans have lost their jobs and their health insurance, and are in danger of losing their homes, even as they find themselves in the path of a lethal disease. The Trump presidency “is the symptom of the denigration of science and the gutting of the public contract about what we owe each other as citizens,” said Dr. Joia S. Mukherjee, the chief medical officer of Partners in Health in Boston.
One lesson that will surely be learned is that the country needs to be better prepared for microbial assaults, said Dr. Julie Gerberding, a former director of the C.D.C.
“This is not a once-in-a-century event. It’s a harbinger of things to come.”
