Cruise Ship Outbreak Summary

cruise ship CDC information CDC Ship Ratings
 

Cruise ships participating in the Vessel Sanitation Program are required to report the total number of gastrointestinal (GI) illness cases (including zero cases) evaluated by the medical staff before the ship arrives at a U.S. port, when sailing from a foreign port. A separate notification is required when the GI illness count exceeds 2% of the total number of passengers or crew onboard. The data below were obtained from these surveillance reports and from CDC-led investigations. The GI illness cases reported are totals for the entire voyage and do not represent the number of active (symptomatic) GI cases at any given port of call or at disembarkation.

Cruise ship outbreak updates are posted when they meet the following criteria:

• Fall within the purview of VSP (see about VSP),
• Are sailing on voyages from 3-21 days,
• Are carrying 100 or more passengers,
• Are cruise ships in which 3% or more of passengers or crew reported symptoms of diarrheal disease to the ships medical staff during the voyage, and

• Are gastrointestinal illness outbreaks of public health significance.

The following links provide additional resource information about gastrointestinal illness outbreaks on land and at sea.

What is Norovirus?

Norovirus is so widespread that only the common cold is reported more frequently. The CDC estimates that there are 23 million land-based Norovirus cases each year in the U.S., affecting one in 12 people, or 8% of the population. In contrast, the number of cruise passengers affected is .028% of the 8 million cruising population, or 1 in 3,600 of those who vacation aboard ships. Symptoms of norovirus include mild stomach upset with vomiting and diarrhea, usually lasting between one and three days. The illness generally resolves without treatment or long-term consequences.

What is E. Coli

bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract. The types of E. coli that can cause diarrhea can be transmitted through contaminated water or food, or through contact with animals or persons.

E. coli consists of a diverse group of bacteria. Pathogenic strains are categorized into pathotypes. Six pathotypes are associated with diarrhea and collectively are referred to as diarrheagenic E. coli.

Shiga toxin-producing E. coli(STEC)—STEC may also be referred to as Verocytotoxin-producing E. coli(VTEC) or enterohemorrhagicE. coli(EHEC). This pathotype is the one most commonly heard about in the news in association with foodborne outbreaks.

Enterotoxigenic E. coli (ETEC)

Enteropathogenic E. coli (EPEC)

Enteroaggregative E. coli (EAEC)

Enteroinvasive E. coli (EIEC)

Diffusely adherent E. coli (DAEC)

Health officials recommend that the best way cruise passengers can protect themselves from getting ill is to wash their hands frequently and thoroughly.
