5. Cases could be 6–24x higher than reported
The number of people infected with COVID-19 in 10 regions analyzed by the Centers for Disease Control and Prevention could be six to 24 times higher than the reported rates, according to data released by the agency Tuesday.
The big picture: The analysis, based on antibody tests, shows that many people who did not exhibit symptoms may have been unknowingly spreading the virus within their communities, Axios' Marisa Fernandez writes.
Why it matters: The U.S. has been testing about 700,000 people a day. But the agency's new report shows the testing load is still far from enough, given the country's enormous caseload.
Details: The report is the largest of its kind to date, analyzing blood tests between March 23 and May 12 from commercial labs in Connecticut, Louisiana, Minnesota, Missouri, New York City, Philadelphia, San Francisco, South Florida, Utah and western Washington state.
- In June, the CDC's smaller collection of blood tests from cities and states was one of the agency's first indicators that there were tens of millions more cases than what the country was finding.
Worth noting: Some of the data is old, with the most recent tests conducted in May. A lot can change over the course of two months, as STAT points out.
