A cruise ship with more than 100 passengers and crew suffering from a gastrointestinal ailment caused by Norovirus, have arrived in San Diego, a cruise line spokeswoman said on Thursday. The Crown Princess, carrying 3,141 passengers in all, docked in San Diego and planned to continue on to Los Angeles on its normal itinerary along the coast of California and Northern Mexico. Onboard testing proved the presence of Norovirus, said Princess Cruises spokeswoman Karen Candy. Outbreaks of Norovirus have been reported by nearly a dozen cruise lines sailing from U.S. ports in recent years, including Holland America, Celebrity, Cunard Line and a National Geographic cruise on Lindblad Expeditions.
