Malaria is a preventable infection that can be fatal if left untreated.
Prevent infection by taking prescription antimalarial drugs and protecting yourself against mosquito bites. Risk for malaria is high all year in all areas of Haiti and in rural areas of the Dominican Republic, especially areas bordering Haiti. You are not at risk if you travel only to other Caribbean islands. Travelers to Haiti and rural Dominican Republic should take chloroquine to prevent malaria. A certificate of yellow fever vaccination may be required for entry into certain areas of these countries if you are arriving from a tropical South American or sub-Saharan African country.
