Risk classification criteria

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 Travel Health Notices

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.
