Two more sailors have tested positive for the coronavirus aboard the USNS Mercy, a Navy hospital ship docked at the Port of Los Angeles, making for three crew members who have been taken to shore and into isolation.

One crew member tested positive on Thursday, April 9, and another had a confirmed positive test returned on Friday, April 10, said Navy Lt. Joe Pfaff.

The three are being isolated in a military medical facility. Any crew members who had contact the sailors have also been isolated and removed from the ship.

On Wednesday, April 8, the ship had its first sailor confirmed positive for the virus.

None of the three sailors with the positive coronavirus tests were in contact with any of the ship’s patients, officials said.

The 1,000-bed floating hospital was stationed at the port to treat patients who don’t have coronavirus so Los Angeles-area hospitals have more room to focus on those with COVID-19.

The Mercy has taken aboard more than 40 patients since it docked on March 27. Doctors on board have performed multiple minor surgeries, including repairing an abdominal stab wound.
