It’s one of the most urgent questions in the United States right now: How many people have actually been tested for the coronavirus?
This number would give a sense of how widespread the disease is, and how forceful a response to it the United States is mustering. But for days, the Centers for Disease Control and Prevention has refused to publish such a count, despite public anxiety and criticism from Congress. On Monday, Stephen Hahn, the commissioner of the Food and Drug Administration, estimated that “by the end of this week, close to a million tests will be able to be performed” in the United States. On Wednesday, Vice President Mike Pence promised that “roughly 1.5 million tests” would be available this week.
But the number of tests performed across the country has fallen far short of those projections, despite extraordinarily high demand, The Atlantic has found.
“The CDC got this right with H1N1 and Zika, and produced huge quantities of test kits that went around the country,” Thomas Frieden, the director of the CDC from 2009 to 2017, told us. “I don’t know what went wrong this time.”
Through interviews with dozens of public-health officials and a survey of local data from across the country, The Atlantic could only verify that 1,895 people have been tested for the coronavirus in the United States, about 10 percent of whom have tested positive. And while the American capacity to test for the coronavirus has ramped up significantly over the past few days, local officials can still test only several thousand people a day, not the tens or hundreds of thousands indicated by the White House’s promises.
