After several cases of cholera among visitors to Cuba, the United States has issued an advisory for travelers to the island.
The Pan American Health Organization reports five confirmed cases of cholera in July and August among visitors to Cuba, including three who visited Havana.
The U.S. Interests Section in Havana recommended that visitors avoid untreated water, be careful about eating fresh foods, and wash their hands frequently.
The United States embargoed travel to Cuba 50 years ago, but allows "cultural exchanges," the number of which have been growing steadily.
Three people died and more than 400 fell ill in an outbreak of cholera last summer, and 51 more cases were reported in January.
