Nearly 10% of the passengers onboard a Ruby Princess cruise became ill with symptoms including vomiting and diarrhea between Feb. 26 and March 5, according to the Centers for Disease Control and Prevention.
The cause of the outbreak that sickened 284 passengers and 34 crew members is not known.
The crew of the Galveston, Texas-based ship said it responded with increased cleaning and disinfection procedures, informing embarking passengers of the issue and collecting stool specimens from gastrointestinal illness cases, which were delivered to the CDC.
