An outbreak of cholera has been ongoing in the Dominican Republic since November 2010. Cases continue to remain at elevated levels. The provinces with the highest number of cases in September 2011 were San Juan, Santo Domingo, and the National District. Dominican Republic authorities are taking measures to prevent the spread of the disease. The risk of cholera for travelers to the Dominican Republic is likely very low if precautions are taken. Travelers should consume only safe food and water.
