Dengue outbreaks occur in many countries of the world, including in the Americas, Africa, the Middle East, Asia, and the Pacific Islands.
Anyone who lives in or travels to an area with risk of dengue is at risk for infection. Before you travel, find country-specific travel information to help you plan and pack.
Almost half of the world’s population, about 4 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.
Dengue has emerged as a worldwide problem since the 1960s. The disease is common in many popular tourist destinations in the Caribbean (including Puerto Rico), Central and South America, Southeast Asia, and the Pacific Islands. In the United States, local cases and limited spread of dengue does occur periodically in some states with hot, humid climates and Aedes mosquitoes.
