Outbreak Updates for International Cruise Ships
Cruise ships participating in the Vessel Sanitation Program are required to report the total number of gastrointestinal (GI) illness cases (including zero cases) evaluated by the medical staff before the ship arrives at a U.S. port, when sailing from a foreign port. A separate notification is required when the GI illness count exceeds 2% of the total number of passengers or crew onboard. The data below were obtained from these surveillance reports and from CDC-led investigations. The GI illness cases reported are totals for the entire voyage and do not represent the number of active (symptomatic) GI cases at any given port of call or at disembarkation.
Cruise ship outbreak updates are posted when they include the following criteria:
- fall within the purview of VSP (see about VSP),
- are sailing on voyages from 3-21 days,
- are carrying 100 or more passengers, and
- are cruise ships in which 3% or more of passengers or crew reported symptoms of diarrheal disease to the ships medical staff during the voyage, and
- are gastrointestinal illness outbreaks of public health significance.
The following links provide additional resource information about gastrointestinal illness outbreaks on land and at sea.
CDC has not verified all of the case numbers represented in the following updates.
