The Grand Princess cruise ship is unloading all of its passengers in Oakland, California after a string of coronavirus cases brought the ship into port.
But 19 crew members who tested positive for the virus will remain on the ship with more than 1,000 other staff, Princess Cruises said in an email update on Tuesday.
The cruise line said that those 19 staff were "asymptomatic."
But some limited research has suggested that infected people who don't have symptoms can pass the coronavirus to others. In one case, a woman in Wuhan, China, passed the virus to five family members without ever getting sick herself.
The Grand Princess arrived in Oakland on Monday after sitting off the coast of the San Francisco Bay Area for four days while officials planned what to do with its passengers. As of Monday night, 407 passengers had left the ship and begun traveling to US military bases for quarantine. Non-US citizens were put onto charter flights.
