Chikungunya Hits Mainland
The first locally acquired case of chikungunya, a mosquito-borne disease, was reported July 17 in Florida. This newly reported case represents the first time that mosquitoes in the continental United States are thought to have spread the virus to a non-traveler. Although CDC does not expect widespread cases of chikungunya in the United States this summer, American travelers infected overseas may continue to return and bring the virus with them.
- Chikungunya virus is transmitted to people by two species of mosquitoes,Aedes aegypti and Aedes albopictus. Both species are found in the southeastern United States and limited parts of the Southwest; Aedes albopictus is also found further north up the East Coast, through the Mid-Atlantic States, and is also found in the lower Midwest.
- People infected with chikungunya virus typically develop fever and joint pain. Other symptoms can include muscle aches, headaches, joint swelling or rash. This virus is not spread person to person. There is no vaccine and no specific treatment for infection.
- The best way to protect yourself and your family from chikungunya is to prevent being bitten by mosquitoes by using insect repellent, wearing long sleeves and pants, using air conditioning or window/door screens to keep mosquitoes outside, and reducing mosquito breeding ground such as standing water.
CDC is currently working with the Florida Department of Health to assess whether there are additional locally acquired cases and is providing consultation on ways to prevent further spread of the virus by controlling mosquitoes and educating people about personal and household protection measures to avoid mosquito bites.
