Speaking of "weird" numbers
State and Federal Data on COVID-19 Testing Don’t Match Up
The CDC has quietly started releasing nationwide numbers. But they contradict what states themselves are reporting.ROBINSON MEYER & ALEXIS C. MADRIGALHow many coronavirus tests have been conducted in the United States? For the first time since February, the federal government has an answer. The Centers for Disease Control and Prevention now say that 10,847,778 coronavirus tests have been conducted nationwide. These tests have found about 1.4 million positive cases.
These figures come from a new CDC website that appeared online last week with little fanfare. It marks an important but much belated development for the nation’s premier public-health agency, which has struggled to manage a pandemic that has killed more than 81,000 Americans and plunged the U.S. economy into a recession. Not since February 29, when the nationwide death toll stood at five, has the CDC published anything close to a comprehensive daily count of tests.
For the past 11 weeks, the COVID Tracking Project at The Atlantic has been the country’s only reliable source for national testing data. (The tracker compiles the number of tests reported by each U.S. state and territory daily.) While the CDC has provided only occasional and rudimentary tallies of total tests, data from the COVID Tracking Project have been used by Johns Hopkins University, governors and members of Congress, and the White House.
With the new CDC site, the federal government is providing regular testing data again, and for the first time ever, it is doing so on a state-by-state level. But an initial analysis of the CDC’s state-level data finds major discrepancies between what many states are reporting and what the federal government is reporting about them. In Florida, for example, the disparity is enormous. The state government reported on Friday that about 700,000 coronavirus tests have been conducted statewide since the beginning of the outbreak. This count should be authoritative: Governor Ron DeSantis has ordered hospitals and doctors to report their test results to the Florida Department of Health. Yet the CDC reported more than 919,000 tests in the state in that same period. That’s 31 percent more tests than Florida itself seems to think it has conducted. (Because the CDC says it does not update its data on the weekends, we have, throughout this article, compared its figures against the numbers reported by each state on Friday.) When we asked the CDC to explain the discrepancy in Florida, the agency declined to comment on the record.
“If this is what they’re getting, the CDC should pick up the phone and call the state of Florida and say, ‘What’s happening?’” Ashish Jha, the K.T. Li Professor of Global Health at Harvard, told us.
Given the complexity and the multisource nature of the data, some variations should certainly be anticipated. But the inconsistencies we found suggest ...
