Dengue around the world
Dengue is a common disease in many countries globally, affecting the Americas, Africa, the Middle East, Asia, and the Pacific Islands.
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 febrile illness in areas with risk.
Dengue outbreaks are reported frequently in these regions, including many popular tourist destinations in:
- the Caribbean
- Central America
- South America
- Southeast Asia
- Pacific Islands
Mosquitoes that can spread dengue usually live in places below 6,500 feet. The chances of getting dengue from mosquitoes living above that altitude are very low.
Information for travelers
CDC has identified a higher-than-expected number of dengue cases among returning U.S. travelers from certain countries in recent months. See the list below for these countries or visit CDC’s travel notices for dengue webpage for additional countries with dengue travel health notices in place.
- Cuba
- El Salvador
- French Polynesia
- Mexico
Anyone who lives in or travels to an area with risk of dengue is at risk for infection. More detailed maps about dengue risk by region are available in the CDC Yellow Book.

Risk classification criteria
Risk classifications are assigned based on the highest risk level identified within that destination. Classifications are updated every two years and align with CDC Yellow Book releases.
- Frequent/continuous risk: evidence of more than 10 dengue cases in at least 3 of the previous 10 years.
- Sporadic/uncertain risk: evidence of at least 1 locally acquired dengue case during the last 10 years.
