Dengue is a disease caused by an arbovirus virus, spread
by the bite of an infected Aedes aegypti and A. albopictus
mosquito. The disease is common in most tropical and subtropical areas
including the Caribbean, Mexico, South and Central America, Pacific,
Asia, and parts of tropical Africa. Dengue rarely occurs in the United
States and reported cases are usually associated with travel to a
high-risk area. However, sporadic outbreaks of Dengue have been
documented in Florida, Guam, Hawaii, and Puerto Rico. During 2002 to
2008, about 32 Wisconsin residents reported travel-associated Dengue
illnesses. Illness ranges from 3 to 14 days after a bite of an infected
mosquito. Symptoms of illness can be mild to severe, including fever,
severe frontal headache, pain behind the eyes, arthalgia, myalgia,
maculopapular rash, mild bleeding, hemorrhagic fever that can result in
circulatory instability, shock, and death

Data and Statistics
Some tips to protect yourself:
- Use effective mosquito repellant and apply according to the label

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.
