Classifications are reviewed every two years and align with CDC Yellow Book maps
- Frequent/continuous risk: evidence of more than 10 locally-acquired dengue cases in at least 3 of the previous 10 years. Areas with more than 75% of the country classified as frequent/continuous risk were also grouped in this category, even if some areas have limited or no reported dengue activity.
- Sporadic/uncertain risk: evidence of at least 1 locally acquired dengue case during the last 10 years.
- Risk varies by region: Dengue activity varies across the country; please review maps to evaluate risk at the sub-national level.
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
CDC provides global dengue travel notices about countries reporting higher than usual numbers of cases, or with a higher-than-expected number of dengue cases among U.S. travelers returning from those areas. Learn more about the current situation.
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
