MADISON, Wis. -

Officials announced Monday the first human case of West Nile virus in 2013 was diagnosed in a Dane County resident.

During 2012, 57 Wisconsin residents developed symptomatic WNV infection, and five of the reported cases occurred among Dane County residents, according to a release.

Officials also said 10 birds have tested positive for WNV statewide this season. The birds were found in Chippewa, Dunn, Fond du Lac, Jefferson, Oneida, Rock, Vilas, Washington, and Wood counties.

Infected birds serve as an early warning by indicating that WNV is present in an area, and those cases emphasize the need for residents to protect themselves against mosquito bites, according to the release.

The likelihood of contracting WNV infection is low and most people infected with the virus will not have symptoms, according to the release.

Officials said those who do become ill may develop a fever, headache, rash, muscle and joint aches, nausea, vomiting and fatigue that can last a few days. Symptoms can begin three to 15 days after being bitten by an infected mosquito.

Officials encourage everyone to take precautions and protect themselves from mosquito bites.
