Official advice
What this page shows, and what it misses
Every outbreak of gastrointestinal illness (vomiting and diarrhoea) on a cruise ship that CDC's Vessel Sanitation Program has posted, from its current list, its list of recent years and the archived lists back to 1993. CDC posts an outbreak only when the ship sails under its jurisdiction — a voyage with both U.S. and foreign ports — and 3% or more of passengers or crew report illness. It misses smaller outbreaks and voyages outside CDC's jurisdiction. Case counts are totals for the whole voyage, not people ill at one time. CDC's older lists (to 2018) also required a voyage of 3–21 days with 100 or more passengers. The list is CDC's, not a count by Global Incident Tracker.
Data: Centers for Disease Control and Prevention, Vessel Sanitation Program, cruise ship outbreak lists and outbreak reports (cdc.gov and archive.cdc.gov) — public domain U.S. Government work.
FAQ Cruise ship outbreaks
How many cruise ship outbreaks have there been in 2026?
As of 2 November 2026, CDC's Vessel Sanitation Program has posted 9 gastrointestinal illness outbreaks on cruise ships in 2026 (23 in 2025), 5 of them caused by norovirus. Most recent: Lindblad Expeditions' National Geographic Sea Bird, sailing 15 Jul – 20 Jul 2026, cause: unknown. Since 1993 CDC has posted 428; most by line: Holland America Line (79) and Princess Cruises (76).
Which cruise line has the most outbreaks?
In CDC's list since 1993, Holland America Line has the most posted outbreaks (79). Lines that run more ships and more voyages under CDC's jurisdiction have more chances to reach the threshold, so the raw count is not a rate per passenger.
When does CDC post a cruise ship outbreak?
CDC's Vessel Sanitation Program posts an outbreak when the ship is under its jurisdiction — a voyage that calls at both U.S. and foreign ports — and 3% or more of passengers or crew report gastrointestinal illness to the ship's medical staff. It may also post other outbreaks of public health significance.
