  • Over 140 people aboard Royal Caribbean's Navigator of the Seas, including 134 passengers and seven crew members, became ill with vomiting and diarrhea during a round-trip cruise from Los Angeles to Mexico.
  • The outbreak occurred after the ship departed from Los Angeles on July 4, with the vessel docking in Puerto Vallarta on July 8 and returning to Los Angeles on July 11.
  • Passengers who reported illness were isolated, and the ship underwent a thorough cleaning, with stool samples also collected for testing.
  • The CDC has not yet determined the cause of the outbreak, though vomiting and diarrhea are common signs of norovirus.
  • This incident follows a similar outbreak last September, when 180 people became sick on Royal Caribbean’s Radiance of the Seas during an Alaska cruise.
