Seattle’s Leaders Let Scientists Take the Lead. New York’s Did Not

The first diagnosis of the coronavirus in the United States occurred in mid-January, in a Seattle suburb not far from the hospital where Dr. Francis Riedo, an infectious-disease specialist, works. When he heard the patient’s details—a thirty-five-year-old man had walked into an urgent-care clinic with a cough and a slight fever, and told doctors that he’d just returned from Wuhan, China—Riedo said to himself, “It’s begun.”

For more than a week, Riedo had been e-mailing with a group of colleagues who included Seattle’s top doctor for public health and Washington State’s senior health officer, as well as hundreds of epidemiologists from around the country; many of them, like Riedo, had trained at the Centers for Disease Control and Prevention, in Atlanta, in a program known as the Epidemic Intelligence Service. Alumni of the E.I.S. are considered America’s shock troops in combatting disease outbreaks. The program has more than three thousand graduates, and many now work in state and local governments across the country. “It’s kind of like a secret society, but for saving people,” Riedo told me. “If you have a question, or need to understand the local politics somewhere, or need a hand during an outbreak—if you reach out to the E.I.S. network, they’ll drop everything to help.”

Riedo is the medical director for infectious disease at EvergreenHealth, a hospital in Kirkland, just east of Seattle. Upon learning of the first domestic diagnosis, he told his staff—from emergency-room nurses to receptionists—that, from then on, everything they said was just as important as what they did. One of the E.I.S.’s core principles is that a pandemic is a communications emergency as much as a medical crisis. Members of the public entering the hospital, Riedo told his staff, must be asked if they had travelled out of the country; if someone had respiratory trouble, staff needed to collect as much information as possible about the patient’s recent interactions with other people, including where they had taken place. You never know, Riedo explained, which chance encounter will shape a catastrophe. There are so many terrifying possibilities in a pandemic; information brings relief.

A national shortage of diagnostic kits for the new coronavirus meant that only people who had recently visited China were eligible for testing. Even as EvergreenHealth’s beds began filling with cases of flulike symptoms—including a patient from Life Care, a nursing home two miles away—the hospital’s doctors were unable to test them for the new disease, because none of the sufferers had been to China or been in contact with anyone who had. For nearly a month, as the hospital’s patients complained of aches, fevers, and breathing problems—and exhibited symptoms associated with covid-19, such as “glassy” patches in X-rays of their lungs—none of them were evaluated for the disease. Riedo wanted to start warning people that evidence of an outbreak was growing, but he had only suspicions, not facts.

At the end of February, the C.D.C. began allowing the testing of patients with unexplained respiratory-tract infections or “fever and/or symptoms of acute respiratory illness.” Riedo called a friend—an E.I.S. alum at the local department of health. If he sent her swabs from two patients who had needed ventilators but had tested negative for influenza and other common respiratory diseases, would she test them for covid-19? At that point, there had been only sixteen detections of the coronavirus in the U.S., and only the one in Washington State. “I can’t remember why we picked those two patients,” Riedo told me. “I was sure they’d be negative. But we thought it would be good to start collecting data, and it was a way to make sure the testing lab was working.” The health official told him to send the samples to her lab.

Riedo remembered that other local researchers had been conducting a project called the Seattle Flu Study. For months, they had collected nasal swabs from volunteers, to better understand how influenza spread through the community. During the previous few weeks, the researchers, in quiet violation of C.D.C. guidance, had jury-rigged a coronavirus test in their lab and had started using it on their samples. They had just found a positive hit: a high-school student in a suburb twenty-eight miles from Seattle, with no recent history of foreign travel and no known interactions with anyone from China. The boy wasn’t seriously ill; if the researchers hadn’t done the test, the infection probably never would have been detected. The genetic sequence of the boy’s virus was unnervingly similar to that of the man with the first known case, even though the researchers couldn’t find any connections between them. The frightening implication was that the coronavirus was already so widespread that contagion was passing invisibly among community members.

At seven-forty that evening, Riedo got a call from his friend at the public-health lab. Both of the samples he had sent were positive. Riedo sent over swabs from nine other EvergreenHealth patients. Eight were positive. Riedo grabbed the patients’ charts and saw that seven of them had come from the Life Care nursing home. It didn’t make any sense: nursing-home residents don’t travel, and interact mainly with just family members and staff.

Riedo sent in more samples. Most of the patients tested positive, including a woman who had been told that she had pneumonia, another woman who had complained of sweating and clammy hands, and a man in his fifties with serious respiratory problems. For three days, dozens of that man’s family members had sat at his bedside in the hospital, coming in and out of the building and going from home to work, visiting restaurants and shaking people’s hands, inadvertently exposing themselves and others to covid-19.

At that moment, there were no known U.S. coronavirus fatalities. Schools, restaurants, and workplaces were open. Stock markets were near all-time highs. But when Riedo stopped to calculate how many of his hospital employees had been exposed to the coronavirus he had to quit when his list surpassed two hundred people. “If we sent all of those workers home for two weeks, which is what the C.D.C. was recommending, we’d have to shut down the entire hospital,” he told me. He felt like a man who, having casually swatted at a buzzing insect, suddenly realized that he was beneath a beehive.

The next day, the man with all the family visitors died. It was America’s first known covid-19 death. Riedo called his wife. “I told her I didn’t know when I would be coming home,” he said to me. “And then I started e-mailing everyone I knew to say we were past containment. It had already escaped.” (...)

On February 28th, around the time that Riedo learned of the covid-19 cluster at the Life Care nursing home, the news was also relayed to another E.I.S. alum, Dr. Jeff Duchin, the top public-health physician for Seattle and surrounding King County. To Duchin, the cluster suggested that there was already an area-wide outbreak. He told Dow Constantine, the King County Executive, that it was time to start considering restrictions on public gatherings and telling residents to stay home. This advice struck Constantine as possibly crazy. There were only two dozen covid-19 diagnoses in the entire nation. Life looked normal. How could people be persuaded to stop going to bars, much less to work, just because a handful of old people were sick?

Constantine told me, “Jeff recognized what he was asking for was impractical. He said if we advised social distancing right away there would be zero acceptance. And so the question was: What can we say today so that people will be ready to hear what we need to say tomorrow?” In e-mails and phone calls, the men began playing a game: What was the most extreme advice they could give that people wouldn’t scoff at? Considering what would likely be happening four days from then, what would they regret not having said?

Even for public-health professionals, the trade-offs were painful to contemplate. At a meeting of public-health supervisors and E.I.S. officials in Seattle, an analyst became emotional when describing the likely consequences of shutting Seattle’s schools. Thousands of kids relied on schools for breakfast and lunch, or received medicine like insulin from school nurses. If schools closed, some of those students would likely go hungry; others might get sick, or even die. Everyone also knew that, if the city shut down, domestic-violence incidents would rise. And what about the medical providers who would have to stop working, because they had to stay home with young kids? “It was overwhelming,” one E.I.S. official told me. “Every single decision had a million ripples.”  (...)

The initial coronavirus outbreaks in New York City emerged at roughly the same time as those in Seattle. But the cities’ experiences with the disease have markedly differed. By the second week of April, Washington State had roughly one recorded fatality per fourteen thousand residents. New York’s rate of death was nearly six times higher.

There are many explanations for this divergence. New York is denser than Seattle and relies more heavily on public transportation, which forces commuters into close contact. In Seattle, efforts at social distancing may have been aided by local attitudes—newcomers are warned of the Seattle Freeze, which one local columnist compared to the popular girl in high school who “always smiles and says hello” but “doesn’t know your name and doesn’t care to.” New Yorkers are in your face, whether you like it or not. (“Stand back at least six feet, playa,” a sign in the window of a Bronx bodega cautioned. “covid-19 is some real shit!”) New York also has more poverty and inequality than Seattle, and more international travellers. Moreover, as Mike Famulare, a senior research scientist at the Institute for Disease Modeling, put it to me, “There’s always some element of good luck and bad luck in a pandemic.”

It’s also true, however, that the cities’ leaders acted and communicated very differently in the early stages of the pandemic. Seattle’s leaders moved fast to persuade people to stay home and follow the scientists’ advice; New York’s leaders, despite having a highly esteemed public-health department, moved more slowly, offered more muddied messages, and let politicians’ voices dominate.
