Carl Bergstrom quoted in The Atlantic on the "pandemic spiral"

Carl Bergstrom is quoted in an article in The Atlantic on the U.S. response to the COVID-19 pandemic. The article argues that as the U.S. heads toward the winter, the country is going round in circles, making the same conceptual errors that have plagued it since spring.

The U.S. enters the ninth month of the pandemic with more than 6.3 million confirmed cases and more than 189,000 confirmed deaths. The toll has been enormous because the country presented the SARS-CoV-2 coronavirus with a smorgasbord of vulnerabilities to exploit. But the toll continues to be enormous—every day, the case count rises by around 40,000 and the death toll by around 800—because the country has consistently thought about the pandemic in the same unproductive ways.


The spiral begins when people forget that controlling the pandemic means doing many things at once. The virus can spread before symptoms appear, and does so most easily through five P’s: people in prolonged, poorly ventilated, protection-free proximity. To stop that spread, this country could use measures that other nations did, to great effect: close nonessential businesses and spaces that allow crowds to congregate indoors; improve ventilation; encourage mask use; test widely to identify contagious people; trace their contacts; help them isolate themselves; and provide a social safety net so that people can protect others without sacrificing their livelihood. None of these other nations did everything, but all did enough things right—and did them simultaneously. By contrast, the U.S. engaged in …

1. A Serial Monogamy of Solutions

Stay-at-home orders dominated March. Masks were fiercely debated in April. Contact tracing took its turn in May. Ventilation is having its moment now. “It’s like we only have attention for only one thing at a time,” says Natalie Dean, a biostatistician at the University of Florida.

As often happens, people sought easy technological fixes for complex societal problems. For months, President Donald Trump touted hydroxychloroquine as a COVID-19 cure, even as rigorous studies showed that it isn’t one. In August, he switched his attention to convalescent plasma—the liquid fraction of a COVID-19 survivor’s blood that might contain virus-blocking antibodies. There’s still no clear evidence that this century-old approach can treat COVID-19 either, despite grossly misstated claims from FDA Commissioner Stephen Hahn (for which he later apologized). More generally, drugs might save some of the very sickest patients, as dexamethasone does, or shorten a hospital stay, as remdesivir does, but they are unlikely to offer outright cures. “It’s so reassuring to think that a magic-bullet treatment is out there and if we just wait, it’ll come and things will be normal,” Dean says.

Other strategies have merit, but are wrongly dismissed for being imperfect. In July, Carl Bergstrom, an epidemiologist and a sociologist of science at the University of Washington, argued that colleges cannot reopen safely without testing all students upon entry. “The gotcha question I’ve handled most from reporters since is: This school did entry testing, so why did they get an outbreak?” he says. It’s because such testing is necessary for a safe reopening, but not sufficient. “If you do it and screw everything else up, you’ll still have a big outbreak,” Bergstrom adds.
