There are 11 passengers and 10 crew members on the Grand Princess cruise ship that are “symptomatic,” Gov. Gavin Newsom said in a press conference today.

The ship, which is currently off the coast, is holding hundreds of passengers, Newsom said.

The ship, which departed from San Francisco to Mexico from February 10-21, returned to San Francisco and left for Hawaii on February 21.

Over 50% of the 2,500 passengers from the cruise to Mexico are Californians, Newsom said. Some of these passengers stayed and went on the second cruise to Hawaii on the same ship.

They are sharing the list of passengers with the Centers for Disease Control and Prevention (CDC) and local health care partners to contact all individuals who were on the cruise ship.
