Fight the Bite Slogan

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, the 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 onset ranges from 3 to 14 days after the bite from an infected mosquito. Symptoms of illness can be mild to severe, including fever, severe frontal headache, pain behind the eyes, arthralgia, myalgia, maculopapular rash, mild bleeding, and hemorrhagic fever that can result in circulatory instability, shock, and death.
