West Nile Virus

West Nile virus is transmitted by the bite of an infected mosquito. It is widespread in Africa, southern Europe, and western Asia. It first appeared in the United States in 1999 in the greater New York City area. By 2002, it spread to 44 states. It has caused illness and mortality in humans, wildlife and domestic animals, especially birds and horses. In humans, it causes an influenza-like illness that may lead to aseptic meningitis, encephalitis, and death, especially in persons over 50 years of age. West Nile virus is important because it affects not only people, but also wildlife (including many game animals), and some domestic animals, especially horses.

In conjunction with the Ohio Department of Health the Division of Environment collects mosquitoes and packages them for shipment to the State Laboratory for data collection purposes.  The division aggressively treats areas of concern.

Area residents are being encouraged to be prepared and take personal precautions against mosquitoes by using mosquito repellant, remaining indoors at peak times, wearing appropriate clothing, and identifying and eliminating standing water in and around their homes.  For further information please read our fact sheet  or click the following links.
