Planning to go on a cruise this year? This past week, a Royal Caribbean ship, Ovation of the Sea, had 195 cases of gastrointestinal illness. One of the largest cruise line ships, it was carrying 5800 people, and was at sea for 14 days off the coast of Australia.
Controlling illness on cruise ships is a challenge. Over the past 4 years, there have been 10 or so ships that meet the conditions for reporting by CDC (
CDC Outbreak Updates for International Cruise Ships). But in order to report by CDC, there is a cutoff - "3% or more of passengers or crew reported symptoms of diarrheal disease to the ships medical staff during the voyage." So in the recent outbreak on the Ovation, it just made that mark at 3.3% on board ill.
This table shows the other cases in the last 6 months.
