West Nile Virus in Wisconsin

West Nile virus, a mosquito-borne infection that can cause serious illness, was found in Wisconsin beginning in 2001. It was first identified in the United States in 1999.

In nature, the virus cycles between birds and mosquitoes. It was only when a mosquito infected with the virus bites a person instead of a bird that people become exposed to this virus. As the mosquito season progresses, more mosquitoes are infected with the virus increasing the risk that people being bitten by mosquitoes can become infected with the virus.
