On October 21, 2010, a cholera outbreak was confirmed by the Haitian National Public Health Laboratory. By November 19, the outbreak had reached every department of the country, and by December 17, a total of 121,518 cases of cholera, resulting in 63,711 hospitalizations and 2,591 deaths, had been reported. By November 16, additional cases of cholera had been confirmed in the neighboring Dominican Republic and in Florida. Several confirmed cases in the Dominican Republic and all confirmed U.S. cases were among travelers from Haiti. This report describes cases of cholera identified in the Dominican Republic and United States and provides recommendations to physicians regarding management of travel-related cases. Travelers who develop watery diarrhea within 5 days after returning from cholera-affected areas should seek health care and report their travel histories. Clinicians should enquire about recent travel when evaluating patients with diarrhea. When cholera is suspected, rehydration should be initiated immediately, a stool specimen should be collected for culture of Vibrio cholerae, and public health authorities should be notified.
