Japanese health officials are conducting a full review of all the crew and guests. Princess Cruises said the delay might last up to 24 hours.

Operated by Carnival Japan, the ship is currently on a 14-day round trip journey. The Diamond Princess ship has 1,045 crew and 2,666 passengers on board.

In a statement, Princess Cruises said: “The safety, security and well-being of all guests and crew is our absolute priority.

“The review of the arriving guests and crew by Japanese health authorities is standard practice after a guest tested positive for coronavirus and we are working closely with the local authorities to provide detailed records to facilitate their review.”

Japan has announced 20 confirmed cases of the coronavirus with no deaths so far.
