Outbreak of Gastroenteritis Illness Aboard the Cruise Ship

On June four, 2000, senior management officials of Cruise Lines notified the workers of the Vessel Sanitation Program (VSP), National Center for Environmental Health (NCEH), Centers for Disease Management and Prevention (CDC), of a virulent disease of gastroenteritis among passengers and crew aboard. In accordance with statutory needs (Part seventy one, Section 215 of the Public Health Service (PHS) Act [Title 42, of the United States Code of Federal Regulations]), ship officers contacted VSP twenty four hours before arriving at a U.S. port to report the total range of cases of gastroenteritis among passengers and crew members.
The ship had embarked passengers in Port Canaveral, Florida, at approximately noon on June a pair of, 2000, and was scheduled to come to Port Canaveral on Monday, June five, 200zero, (Table one). On June 4, 2000, the ship’s doctor reported that by the morning of the third day of the 4-day cruise, approximately fifty (one.nine percent) of 2,601 passengers and 10 (1.1percent) of 930 crew aboard had reported to the ship infirmary with gastroenteritis, characterized primarily by diarrhea (3 or a lot of episodes of loose stools in 24 hours) and vomiting. By that evening, 50 a lot of passengers had reported to the infirmary with gastroenteritis, totaling 100 (3.eightpercent) of the 2,601 passengers sick.
On the idea of those reports (greater than 3p.c of passengers and crew members ill with gastroenteritis), and also the speedy rise in the number of cases, VSP initiated an epidemiologic and environmental investigation. The VSP medical epidemiologist flew to Florida to board the vessel on June five, 200zero, in Port Canaveral, the following port of the vessel’s itinerary and therefore the port of disembarkation for passengers. The VSP epidemiologist was accompanied on the investigation by three environmental health officials from Walt Disney World’s land-primarily based environmental operations and several management officers.
