Chikungunya fever is an arboviral disease transmitted to
humans by the bite of infected Aedes aegypti or A. albopictus
mosquitoes. Chikungunya virus was first isolated from the blood of a
febrile patient in Tanzania in 1953. Outbreaks of Chikungunya fever
have occurred in many areas of Africa, Asia, Europe, and the Pacific
islands. In 2013, for the first time Chikungunya virus was identified in
the Americas on islands in the Caribbean. Chikungunya disease rarely
occurs in the United States and reported cases are usually associated
with travel to a high-risk area. Three cases of Chikungunya virus
infection have been reported in
travel-associated Wisconsin residents since 2007.

- Wear long-sleeved shirts, long pants, socks, and shoes.

with a repellent containing permethrin or DEET will give extra
protection. These repellants are the most effective and most studied.
- Avoid being outside during times of high mosquito activity,
specifically around dawn and dusk.
- Keep window screens repaired so that mosquitoes cannot enter your

outside that may contain standing water.
- Drain standing water from pool or hot tub covers.
- Turn over plastic wading pools and wheel barrows when not in use.
