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. Learn more about illnesses and outbreaks reported to VSP and find information about outbreaks of gastrointestinal illness on cruise ships.
Medical staff on cruise ships under U.S. jurisdiction must send gastrointestinal illness case reports to VSP at specific times:
- Before arriving to a U.S. port from a foreign port. This report is required even when there are no cases of gastrointestinal illness. Cruise ship staff send this report between 24 and 36 hours before the ship arrives at a U.S. port.
- When 2% or more of the passengers or crew have gastrointestinal illness. Cruise ship staff send this report any time the ship is in the United States or within 15 days of arriving at a U.S. port.
- If 3% or more of the passengers or crew have gastrointestinal illness.
VSP posts cruise ship outbreaks when they meet all of the following criteria:
- Are on ships under VSP jurisdiction (see about VSP).
- Are on ships carrying 100 or more passengers.
- Are on voyages from 3-21 days long.
- Are on voyages where 3% or more of passengers or crew report symptoms of gastrointestinal illness to the ship’s medical staff.
VSP may also post information on gastrointestinal illness outbreaks of public health significance that do not necessarily meet the above criteria.
Important Notes
Data on this page are from ship 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) cases of gastrointestinal illness at any given port of call or at disembarkation.
- CDC has not verified all the case numbers represented in the following updates.
