Chikungunya is a disease caused by a virus that is spread through mosquito bites.  Within North America, chikungunya has been found in Mexico, the Caribbean, the continental United States, Puerto Rico, and the U.S. Virgin Islands. Chikungunya is not currently found locally in Arizona; all cases to date have been travel-related.

Chikungunya is spread primarily through mosquito bites.  Chikungunya is spread to people primarily through the bite of infected Aedes aegypti mosquitoes. Aedes aegypti mosquitoes are found in Maricopa County and other parts of Arizona; however, we do not have mosquitoes infected with chikungunya. In Arizona, chikungunya infections have been found only in people who were infected while traveling outside the United States. These mosquitoes bite humans all day long so it is important to protect against mosquito bites whenever you are outside.
