Some passengers aboard a cruise ship that docked this week in San Francisco are having a rough trip.
Princess Cruises confirms 37 of the more than 3,000 passengers on its Crown Princess ship have contracted a stomach ailment called the norovirus. It's extremely contagious.
The ship docked at San Francisco for several hours on Monday and is now en route to Santa Barbara.
The West Coast trip lasts seven days. The itinerary starts and ends in Los Angeles.
The cruise line says none of the passengers elected to leave the ship and that everyone on board is instructed to frequently wash their hands, a key step in stopping the spread of the virus.
The ship’s staff has enhanced the sanitation of high-touch surfaces, like railing, door handles and elevator buttons. Additionally, sick passengers are being confined to their cabins until they are no longer contagious.
There are a total of 3,161 passengers and 1,176 crew members on board.
After Santa Barbara, the ship is scheduled to stop in San Diego and Ensenada before returning to Los Angeles on April 12.
