Three months ago, no one knew that SARS-CoV-2 existed. Now the virus has spread to almost every country, infecting at least 446,000 people whom we know about, and many more whom we do not. It has crashed economies and broken health-care systems, filled hospitals and emptied public spaces. It has separated people from their workplaces and their friends. It has disrupted modern society on a scale that most living people have never witnessed. Soon, most everyone in the United States will know someone who has been infected. Like World War II or the 9/11 attacks, this pandemic has already imprinted itself upon the nation’s psyche.

A global pandemic of this scale was inevitable. In recent years, hundreds of health experts have written books, white papers, and op-eds warning of the possibility. Bill Gates has been telling anyone who would listen, including the 18 million viewers of his TED Talk. In 2018, I wrote a story for The Atlantic arguing that America was not ready for the pandemic that would eventually come. In October, the Johns Hopkins Center for Health Security war-gamed what might happen if a new coronavirus swept the globe. And then one did. Hypotheticals became reality. “What if?” became “Now what?”

As the coronavirus pandemic continues, many people are now overthinking things they never used to think about at all. Can you go outside? What if you’re walking downwind of another person? What if you’re stuck waiting at a crosswalk and someone is there? What if you’re going for a run, and another runner is heading toward you, and the sidewalk is narrow? Suddenly, daily mundanities seem to demand strategy.

Much of this confusion stems from the shifting conversation around the pandemic. Thus far, the official line has been that the new coronavirus, SARS-CoV-2, could be transmitted only through close contact with infected people or contaminated surfaces. But recently, news reports have suggested that the coronavirus can spread through the air. After 60 choir members in Washington State rehearsed together, 45 fell sick, even though no one seemed symptomatic at the time. Now people who were already feeling cooped up are worrying about going outside. Many state guidelines are ambiguous, and medical advice can muddy matters further. When the writer Deborah Copaken came down with COVID-19 symptoms, her doctor chided her for riding her bike through New York City a week earlier. Going outside in the city wasn’t safe, the physician implied, with “viral load everywhere.”

Deep into the worst economic crisis since the Great Depression, Republican leaders had one question for President Barack Obama, as his administration sought nearly $1 trillion in funds from Congress: How are you going to pay for this?

The unemployment rate was greater than 7 percent in January 2009, and would rise above 8 percent by February. Mitch McConnell, then the Senate minority leader, insisted, “The question is not doing nothing versus doing something,” but “the appropriateness of an almost $1 trillion spending bill to address the problem.”

Others in his caucus made similar points. “If you believe this is a good process to spend $800 billion, we’re on different planets,” Lindsey Graham, the Republican senator from South Carolina, declared. Chuck Grassley of Iowa complained that “the package's massive government spending and long-term entitlement commitments … will leave the next generation with trillion dollar deficits.” Lamar Alexander of Tennessee demanded, “Should we ask every American family to increase their $531,000 debt in order to spend money for a stimulus package to try to restart the economy?”

For Geoff Frost, the first sign of the coronavirus culture war came last weekend on the golf course. His country club, located in an affluent suburb of Atlanta, had recently introduced a slew of new policies to encourage social distancing. The communal water jugs were gone, the restaurant was closed, and golfers had been asked to limit themselves to one person per cart. Frost, a 43-year-old Democrat, told me the club’s mix of younger liberals and older conservatives had always gotten along just fine—but the guidelines were proving divisive.  

At the driving range, while Frost and his like-minded friends slathered on hand sanitizer and kept six feet apart, the white-haired Republicans seemed to delight in breaking the new rules. They made a show of shaking hands, and complained loudly about the “stupid hoax” being propagated by virus alarmists. When their tee times were up, they piled defiantly into golf carts, shoulder to shoulder, and sped off toward the first hole.  

On March 13, President Donald Trump promised Americans they would soon be able to access a new website that would ask them about their symptoms and direct them to nearby coronavirus testing sites. He said Google was helping.

That wasn’t true. But in the following days, Oscar Health—a health-insurance company closely connected to Trump’s son-in-law, Jared Kushner—developed a government website with the features the president had described. A team of Oscar engineers, project managers, and executives spent about five days building a stand-alone website at the government’s request, an Oscar spokesperson told The Atlantic. The company even dispatched two employees from New York to meet in person with federal officials in Washington, D.C., the spokesperson said. Then the website was suddenly and mysteriously scrapped.

In the emergency-department waiting room, 150 people worry about a fever. Some just want a test, others badly need medical treatment. Those not at the brink of death have to wait six, eight, 10 hours before they can see a doctor. Those admitted to the hospital might wait a full day for a bed.

I am an emergency-medicine doctor who practices in both Manhattan and Queens; at the moment, I’m in Queens. Normally, I love coming to work here, even though in the best of times, my co-residents and I take care of one of New York City’s most vulnerable, underinsured patient populations. Many have underlying illnesses and a language barrier, and lack primary care.

The new coronavirus has brought American life to a near standstill, closing businesses, canceling large gatherings, and keeping people at home. All of those people must surely be wondering: When will things return to normal?

The answer is simple, if not exactly satisfying: when enough of the population—possibly 60 or 80 percent of people—is resistant to COVID-19 to stifle the disease’s spread from person to person. That is the end goal, although no one knows exactly how long it will take to get there.

There are two realistic paths to achieving this “population-level immunity.” One is the development of a vaccine. The other is for the disease to work its way through the population, surely killing many, but also leaving many others—those who contract the disease and then recover—immune. “They’re just Teflon at that point,” meaning they can’t get infected again and they won’t pass on the disease, explains Andrew Noymer, a public-health professor at the UC Irvine. Once enough people reach Teflon status—though we don’t yet know if recovering from the disease confers any immunity at all, let alone lifelong immunity—normalcy will be restored. (It may also turn out to be the case that people who are immune to the disease can still pass it on under certain circumstances.)*

Around the year 1600, the weather in much of Europe substantially cooled, in the latter phase of what has been called the Little Ice Age. In all, it lasted 300 years. Winters were brutally cold and summers were damp and chilly, greatly curtailing the growing season. Crops failed. People starved. But the change in weather forced English, French, and Dutch fishermen to build improved boats, capable of following fish farther to the west and surviving long trips through the rough seas. Undoubtedly, some of that new boat-building craft led to the ships of today.

Innovation often arises in periods of adversity. In recent weeks, we have seen such welcome invention germinating in the horrendous crisis of the coronavirus. Consider, for example, the many new platforms for online teaching, or the use of cheap Bluetooth smart thermometers able to transmit a person’s fever and geolocation to a distant database, or members of the Toronto Symphony Orchestra performing together and apart from 29 different locations using their smartphones.

For his entire adult life, and for his entire presidency, Donald Trump has created his own alternate reality, complete with his own alternate set of facts. He has shown himself to be erratic, impulsive, narcissistic, vindictive, cruel, mendacious, and devoid of empathy. None of that is new.

But we’re now entering the most dangerous phase of the Trump presidency. The pain and hardship that the United States is only beginning to experience stem from a crisis that the president is utterly unsuited to deal with, either intellectually or temperamentally. When things were going relatively well, the nation could more easily absorb the costs of Trump’s psychological and moral distortions and disfigurements. But those days are behind us. The coronavirus pandemic has created the conditions that can catalyze a destructive set of responses from an individual with Trump’s characterological defects and disordered personality.

On the surface, the American COVID-19 testing regime has finally hit its stride. Over the past five days, the states have reported a daily average of 104,000 people tested, according to data assembled by the COVID Tracking Project, a volunteer collaboration incubated at The Atlantic. Today, the U.S. reported that 1 million people have been tested for the coronavirus—a milestone that the White House once promised it would hit the first week of March.

But things are not going as smoothly as the top-line numbers might suggest. Our reporting has unearthed a new coronavirus-testing crisis. Its main cause is not the federal government, nor state public-health labs, but the private companies that now dominate the country’s testing capacity. Testing backlogs have ballooned, slowing efficient patient care and delivering a heavily lagged view of the outbreak to decision makers.
