At a morning news conference, San Francisco Mayor London Breed said the city was working closely with the United States Coast Guard, CDC and State of California on the Grand Princess issue.

She said decision making was ongoing on where the ship would eventually dock, with multiple sites in California under consideration.

The vessel currently sits off the coast with a number of passengers and crew undergoing testing for coronavirus.

Some 35 passengers and crew have shown flu-like symptoms, while many have recovered, according to a spokesperson.

“There are fewer than 100 guests and crew identified for testing, including all in-transit guests (guests who sailed the previous Mexico voyage and remained on board for the current Hawaii voyage), those guests and crew who have experienced influenza-like illness symptoms on this voyage, and guests currently under care for respiratory illness,” Princess said, in a statement.

“To facilitate this testing, the U.S. Coast Guard will deliver sampling kits to the ship the morning of March 5 via helicopter. Our onboard medical team will administer the test and the samples will be sent in batches by helicopter to a lab in Richmond, California, across the bay from San Francisco.

Public health officials have advised that no guests will be permitted to disembark until all results have been received. Out of an abundance of caution, all guests who have been identified for testing have been asked to remain in their staterooms. We will continue to proceed under the guidance of the U.S. CDC and local authorities.

“Princess Cruises can also confirm the cancellation of the upcoming Grand Princess Hawaii cruise departing on March 7. All guests will receive a full refund of their cruise fare, Princess Air, Princess Cruise Plus pre- and post-cruise hotel packages, prepaid shore excursions and other prepaid items purchased through Princess. Unexpected expenses, such as air change fees, reimbursement of reasonable non-refundable out-of-pocket expenses will be considered on a case-by-case basis. Guests will also receive a Future Cruise Credit equal to 100% of the cruise fare paid on this voyage.”
