Chikungunya Virus: Information for States and Territories

Chikungunya fever is an acute illness associated with severe joint pain and fever. The disease is caused by chikungunya virus (CHIKV), an arthropod-borne virus that is transmitted to humans primarily via the bite of an infected mosquito. According to CDC, we may see an increase in the spread of the virus in the continental United States due to travelers visiting or returning to the U.S. from affected areas in the Caribbean and the Pacific. The first case of the disease being transmitted on U.S. soil was confirmed in Puerto Rico in May 2014.

Visit ArboNET for the current number of cases reported by U.S. states and territories. For more background, please also see fact sheets from CDC below.
