MILWAUKEE (AP) -- West Nile has been found in mosquitoes in Wisconsin's largest city.
According to Milwaukee's health department, officials there have confirmed the virus in mosquito pools for the first time this year.
The mosquitoes were collected and tested as part of the department's surveillance and prevention efforts.
There's been one confirmed case of West Nile in a human so far this year in Wisconsin, in a Dane County resident.
Last year, 57 cases of West Nile virus infection were reported among Wisconsin residents. That's the highest annual number of reported cases since surveillance of the disease began in Wisconsin.
Symptoms may begin three to 15 days after a bite from an infected mosquito. Those include fever, headache, joint aches, nausea, vomiting and fatigue. Some people don't get symptoms.
