Where Dengue Is a Risk: CDC's Country-by-Country Guide for Travelers

Dengue is common across much of the world — in the Americas, Africa, the Middle East, Asia and the Pacific Islands. Almost half of the world's population, about 4 billion people, live in places where there is a risk of catching it, and in many of those places it is often a leading cause of illness with fever. Anyone who lives in or travels to one of these areas can be infected.

Outbreaks are reported often in these regions, including many popular tourist destinations in the Caribbean, Central America, South America, Southeast Asia and the Pacific Islands.

Before you travel

Look up the travel information for your destination country on CDC's travelers' health pages, so you can plan and pack accordingly.

CDC also issues global dengue travel notices when countries report more cases than usual, or when more U.S. travelers than expected come home with dengue from a particular area. As of 2 September 2026, Cuba met the criteria for the high transmission category, with 10 or more cases reported among travelers in the previous three months.

Altitude matters. The mosquitoes that spread dengue usually live below 6,500 feet, and the chance of being infected by mosquitoes above that height is very low.

How countries are classified

CDC reviews the classifications every two years, in line with the maps in the CDC Yellow Book.

• Frequent or continuous risk: more than 10 locally acquired dengue cases in at least 3 of the previous 10 years. A country is also placed here when more than 75% of it falls into this category, even if parts of it have reported little or no dengue.
• Sporadic or uncertain risk: at least 1 locally acquired case in the last 10 years.
• Risk varies by region: dengue activity differs from one part of the country to another, so check the maps for the area you are visiting.
