SPRINGFIELD, IL – The Illinois Department of Public Health has reported a mosquito pool in rural Marion in Williamson County has tested positive for West Nile virus. A total of 14 birds and 12 mosquito pools in Illinois have tested positive for West Nile virus since surveillance for the mosquito-transmitted virus began May 1.

Because the virus is present in Illinois, Dr. Eric E. Whitaker, state public health director, recommends individuals take a number of precautions to reduce contact with mosquitoes:

• Whenever outdoors between dusk and dawn or when mosquitoes are present, wear shoes and socks, long pants and a long-sleeved shirt. Loose-fitting, light colored clothing is best.
• When it is necessary to be outdoors, apply insect repellent as indicated on the repellent label. The more DEET a product contains, the longer the repellant can protect against mosquito bites. However, concentrations higher than 50 percent do not increase the length of protection. For most situations, 10 percent to 25 percent DEET is adequate. Apply repellents to clothes whenever possible; apply sparingly to exposed skin if label permits. Consult a physician before using repellents on young children.
• Check residential screens, including porches and patios, for tears and other openings and repair, as necessary, to prevent mosquito entry.
• Eliminate stagnant water in bird baths, ponds, flowerpots, wading pools, old tires and any other receptacles in which mosquitoes might breed.
