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

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.

The U.S. Centers for Disease Control and Prevention has announced that an unknown illness sickened several people aboard a cruise ship earlier this month.
