NBC-About a dozen sailors aboard the USS Chafee have tested positive for Covid-19 and have been removed from the ship, the Navy confirmed Friday.

“Individuals who were in close contact with those sailors are also off the ship and are in quarantine while they monitor for any symptoms,” Cmdr. Sean Robertson, a Third Fleet spokesperson, said in a statement.

Robertson said the warship, which is docked in San Diego, “remains able to meet its mission.”

“No Chafee sailors have been hospitalized,” the commander said.

Robertson’s statement came on the heels of a Navy Times report that 41 sailors out of a crew of 350 had either tested positive or had “been in close contact with infected shipmates,” including several of the ship’s cooks.

And because of equipment shortages, some sailors on trip over from Hawaii have had to “wear dirty N95 mask for five days,” Navy Times reported.
