WOOD RIVER, IL (KTVI) – Mosquitoes collected in Mitchell, Illinois have tested positive for the West Nile Virus. This is the first to group to test positive for WNV in Madison County this season. Positive mosquito batches have also been found in Cook, DuPage, McHenry, Perry, and St. Clair counties.

Wild birds, especially blue jays and crows, can indicate WNV-prone species in an area. The Madison County Dead Bird Surveillance Program says they accept all perching birds for testing. Examples of perching birds include: crows, blue jays, grackles, starling, sparrows, finches, robins, cardinals, flycatchers, swallows, catbirds, mockingbirds, warbler and wrens. Dead birds will be accepted for testing until October 15, 2013. To report a dead bird, call: (618)296-6079.

Here are some tips to prevent the spread of West Nile Virus:

  • Ensure doors and windows have tight-fitting screens
  • Keep doors and windows shut, especially at night
  • Eliminate sources of standing water where mosquitoes can breed (flowerpots, wading pools, old tires, recepticals, etc.)
  • Apply insect repellent that contains DEET, picaridin, lemon eucalyptus or IR 3535 (according to label)
  • Wear protective clothing when outdoors (long sleeves, pants and socks with shoes)
  • Contact your municipal government to report areas of stagnant water that may produce mosquitoes (roadside ditches, flooded yards, etc.)
