About Mayaro
Mayaro virus has been found in parts of South America, Central America, and the Caribbean. There have been no locally acquired cases of Mayaro reported in the United States, but imported human cases from travelers who visited endemic areas have been reported.
Brazil has reported the highest number of Mayaro cases. Other countries with confirmed cases include Bolivia, Ecuador, French Guiana, Haiti, Peru, Suriname, Trinidad and Tobago, and Venezuela. Mayaro virus transmission might be unrecognized or unreported in other countries.
The primary vector of Mayaro virus is Haemagogus species mosquitoes. The enzootic transmission cycle involves these mosquitoes and non-human primates (e.g., monkeys). The risk for infection is greatest in persons living near or visiting forested areas.
Areas where Mayaro virus has been found include the following countries:
- Brazil, Bolivia, Colombia, Ecuador, French Guiana, Haiti, Peru, Suriname, Trinidad and Tobago, and Venezuela
Countries with probable human disease cases and virus isolation from mosquito:
