The Centers for Disease Control and Prevention (CDC) confirmed it is investigating a not-yet-determined outbreak on a Princess Cruises’ Ruby Princess ship that sickened more than 300 people in recent days.
The agency said that 284 passengers and 34 crew members—out of about 4,000 total people—were sickened onboard the cruise between Feb. 26 and March 5. Their primary symptoms were “vomiting and diarrhea,” it said, adding that the “causative agent” is currently “unknown.”
