A sailor assigned to the USS Nimitz, a Bremerton, Wash.-based aircraft carrier, tested positive for Covid-19 last week after experiencing symptoms while on board the ship, according to three defense officials familiar with the matter.

The positive test makes the Nimitz the Navy's fourth aircraft carrier so far to report a positive case among crew members.


The individual was put into isolation and removed from the ship. Contact tracing — or monitoring those who came into contact with the infected sailor — was done in accordance with Centers for Disease Control and Prevention guidelines, the officials said.
