Chikungunya fever is an arboviral disease transmitted to
humans by the bite of infected Aedes aegypti and A. albopictus
mosquitoes. Chikungunya virus was first isolated from the blood of a
febrile patient in Tanzania in 1953, and outbreaks of Chikungunya fever
have occurred in many areas of Africa and Asia, and most recently in a
limited area of Europe. Chikungunya disease rarely occurs in the United
States and reported cases are usually associated with travel to a
high-risk area. In 2007, two cases of Chikungunya were reported in
travel-associated Wisconsin residents.

- 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.
- Change the water in bird baths, pet dishes and wading pools every

water will drain properly.
