Over 140 passengers and crew members aboard a Royal Caribbean International cruise ship were sickened by a gastrointestinal illness that led to vomiting and diarrhea, according to the Centers for Disease Control and Prevention.

A gastrointestinal outbreak aboard a Royal Caribbean cruise sickened more than 140 people earlier this month, according to a report from the Center for Disease Control and Prevention’s Vessel Sanitation Program.

Royal Caribbean's Navigator of the Seas was on a week-long, round-trip cruise when passengers became sick, the CDC said.
