Chikungunya in the Americas
Updates of chikungunya case counts are publically released every Tuesday evening (MT).
- As of July 18, 2014, local transmission had been identified in 24 countries or territories in the Caribbean, Central America, South America, or North America. A total of 436,586 suspected and 5,724 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.
