More than 100 passengers and crew members on board a cruise ship that docked in San Francisco on Thursday were infected by a highly contagious stomach virus, the Centers for Disease Control and Prevention said on Thursday, the latest such incident on board such a vessel just two months after a deadly hantavirus outbreak on board the MV Hondius.
The outbreak took place onboard the Ruby Princess, which docked in San Francisco on Thursday after a 20 day trip.
In an update issued on Thursday, the CDC reported that the Ruby Princess—a cruise ship operated by Princess Cruises—is experiencing a norovirus outbreak.
According to the update, 102 of the ship’s 3,032 passengers and 23 of its 1,144 onboard crew had reported illnesses due to the virus.
The stomach virus is highly contagious and the CDC noted that the predominant symptoms among the infected on board were diarrhea and vomiting.
