The first signs of West Nile Virus are now showing up in Southern Illinois, with confirmed cases in Gallatin County. The virus is emerging a little earlier than usual this year, with mosquito batches testing positive. Last week, West Nile was found in mosquitoes and a bird in Cook County.

Illinois Department of Public Health spokesperson Melaney Arnold says presence of the virus depends a lot on the weather.

Arnold comments

Your best defense against West Nile is to wear bug repellant at dawn and dusk, when mosquitoes are most active.
