5 USS Roosevelt Sailors Test Positive For COVID-19, Again

The U.S. Navy says five sailors from the USS Theodore Roosevelt who had apparently recovered from the coronavirus have tested positive for a second time, after initially receiving negative test results.

In a statement, the Navy said the sailors had “met rigorous recovery criteria, exceeding CDC guidelines,” including testing negative for the virus at least twice, but have now re-tested positive. The statement said the sailors had been monitoring their health and adhered to social distancing protocols while on board the Roosevelt, which has been docked in Guam following an outbreak infecting hundreds of crew members.

“These five Sailors developed influenza-like illness symptoms and did the right thing reporting to medical for evaluation,” the statement said.

Emphasis mine: not only were they apparently infected for a second time, but they apparently developed symptoms the second time. It is not hyperbole to say that we do not currently have evidence that infection provides any immunity. To be clear it is possible that their earlier positives were false positives, or that their earlier negatives were false negatives, but that does not change that we don’t know whether recovering from the virus grants immunity.
