The Navy's testing of the entire 4,800-member crew of the aircraft carrier - which is about 94% complete - was an extraordinary move in a headline-grabbing case that has already led to the firing of the carrier's captain and the resignation of the Navy's top civilian official.
Roughly 60 percent of the over 600 sailors who tested positive so far have not shown symptoms of COVID-19, the potentially lethal respiratory disease caused by the coronavirus, the Navy says. The service did not speculate about how many might later develop symptoms or remain asymptomatic.
"With regard to COVID-19, we're learning that stealth in the form of asymptomatic transmission is this adversary's secret power," said Rear Admiral Bruce Gillingham, surgeon general of the Navy.
