Passengers on the Grand Princess were told to stay inside their rooms for the rest of the voyage, according to operator Princess Cruises in a statement on Thursday evening.
The cruise line was banned from docking in San Francisco and any other California port until 21 passengers on board the ship are tested for COVID-19 coronavirus. They are currently suffering from flu-like symptoms, and Gov. Gavin Newsom made the move to prevent the vessel from disembarking, meaning that the ship is now floating off the California coast as of Thursday.
The California National Guard, earlier in the day, used helicopters to drop off COVID-19 testing kits on the ship.
Princess Cruises, which also operated the Diamond Princess cruise ship that experienced a severe COVID-19 outbreak off the Japanese coast, said there have been no confirmed coronavirus cases on the Grand Princess.
Newsom has said that 11 passengers and 10 crew members have flu-like symptoms and have to undergo testing before getting off in San Francisco or any other California city.
“It is a dynamic situation as it relates to the cruise ship, but nothing that should be alarming,” he said, according to the local station. Meanwhile, a crew member who had flu-like symptoms was removed from the ship when it made its voyage to Hawaii before testing negative for the new virus.
The Grand Princess can carry about 2,500 passengers approximately 1,100 crew members.
