Chikungunya in the Americas
Updates of chikungunya case counts are publicly released every Wednesday by 12 p.m. MT.
- As of August 15, 2014, local transmission had been identified in 31 countries or territories in the Caribbean, Central America, South America, or North America. A total of 580,526 suspected and 6,030 laboratory-confirmed chikungunya cases had been reported from these areas
(Updated data from the Pan American Health Organization).
- Chikungunya virus likely will continue to spread to new areas in the Americas (North America, Central America, and South America) through infected people and mosquitoes.
- The mosquitoes that transmit the virus are found throughout much of the Americas, including parts of the United States.
- Since chikungunya virus is new to the Americas, most people in the region are not immune. This means they can be infected and spread the virus to other mosquitoes.
