The Trump administration has made many stumbles in its response to the coronavirus pandemic, but one of the key failures was not having enough kits to test for the pathogen once it appeared in the United States. Instead of accepting kits from other countries—including the ones approved by the World Health Organization—the White House went its own way.
On March 17, Deborah Birx, the physician coordinating the administration’s scientific response to the Covid-19 outbreak in the United States, tried to explain the rejections. “It doesn’t help to put out a test where 50 percent or 47 percent are false positives,” Birx told reporters, suggesting that at least some overseas tests were deeply flawed. A few days later, FDA commissioner Stephen Hahn again mentioned the 47-percent error rate in an interview with National Public Radio, attributing it to “an abstract that was recently published in the literature.” He continued: “What that means is that if you had a positive test, it was pretty close to a flip of a coin as to whether it was real or not.”
That sounds reasonable. After all, a test that is no better than a coin flip would do far more harm than good, burdening an already overwhelmed health-care system with a tidal wave of well but worried people. Birx is a highly respected scientist whose resume includes taking on the AIDS epidemic, and Hahn heads perhaps the nation’s most important health agency. But in this case, they appear to have relied on data that, for reasons that are still unclear, has been withdrawn from the scientific literature.
As it happens, both of Birx’s false-positive rates, the “50 percent or 47 percent,” came from a single study. That’s bad enough, if somewhat understandable given how quickly the pandemic has been spreading. Still, scientists are generally loath to base any decisions, including what they eat for breakfast, on a single, unreplicated finding. This time, they appear to have done so on a policy matter of the highest importance.
It’s far worse that the single study had already been retracted. As NPR has now reported, the paper was withdrawn a few days after its publication in a Chinese journal. In other words, the Trump administration may have blocked the importation of some Covid-19 tests at a critical moment in the evolution of the pandemic on the strength of a piece of research that is no longer in the literature.
This case is a particularly dismaying and consequential example of what happens when no one bothers to engage in scientific fact-checking. But it will not be the last time that something we thought we knew about the coronavirus because it was in a published paper will turn out to be wrong.
The last few weeks have seen a blizzard of publications about Covid-19—and, like the outbreak itself in this country, it’s just the beginning. Many of the papers have come from China, where researchers have had more time to study the infection than the rest of the world, but important papers have emerged from Italy, as well.
