Outbreak Updates for International Cruise Ships

The Vessel Sanitation Program (VSP) requires cruise ships to log and report the number of passengers and crew who say they have symptoms of gastrointestinal illness.

Medical staff on cruise ships with a foreign itinerary that visit the U.S. participating in the program must send gastrointestinal illness case reports to VSP at these designated times:

  1. Before arriving to a U.S. port from a foreign port. This initial report is required even when there are no cases of gastrointestinal illness. Staff make this report at least 24 hours before the ship arrives at a U.S. port.
  2. When 2% or more of the passengers or crew have gastrointestinal illness. Staff must send this report any time the vessel is in the United States or within 15 days of arriving at a U.S. port.

Data on this page are from these surveillance reports and from CDC-led investigations. The gastrointestinal illness cases reported are totals for the entire voyage. These cases do not represent the number of active (symptomatic) GI cases at any given port of call or at disembarkation.

VSP posts cruise ship outbreaks when they meet all of the following criteria:

  • Fall within the purview of VSP (see about VSP).
  • Are on voyages from 3-21 days long.
  • Are on ships carrying 100 or more passengers.
  • Are voyages where 3% or more of passengers or crew report symptoms of gastrointestinal illness to the ship’s medical staff.

VSP may also post outbreak updates for gastrointestinal illness outbreaks of public health significance that do not necessarily meet the above criteria.

CDC has not verified all of the case numbers represented in the following updates.
