Mosquitoes found in Elgin trap test positive for WNV
KANE COUNTY—The Kane County Health Department recently reported that a batch of mosquitoes collected in a trap in Elgin, Ill., tested positive for West Nile Virus. This is the second time this summer a trap in northern Kane County yielded evidence of the disease. The first, a trap set in July near Algonquin, Ill., administered by the Illinois Department of Public Health, was found to contain mosquitoes that tested positive for the disease.
The Health Department monitors for WNV activity in the area. Also, as part of its West Nile program, the Health Department is collecting dead birds to be sent to the state lab for testing. Call (630) 444-3040 to report the presence of freshly-dead birds (such as crows or blue jays) to determine if WNV testing is recommended. The birds must not show any signs of decay or trauma.

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Most people with the virus have no clinical symptoms of illness, but some may become ill three-to-14 days after the bite of an infected mosquito. Only about two persons out of 10 who are bitten by an infected mosquito will experience any illness. Illness from West Nile is usually mild and includes fever, headache and body aches, but serious illness, such as encephalitis and meningitis, and death are possible. Persons older than 50 years of age have the highest risk of severe disease.
The best way to prevent West Nile disease or any other mosquito-borne illness is to reduce the number of mosquitoes around your home and to take personal precautions to avoid mosquito bites. Precautions include:
• Avoid being outdoors when mosquitoes are most active, especially between dusk and dawn. Use prevention methods whenever mosquitoes are present.
• When outdoors, wear shoes and socks, long pants and a long-sleeved shirt, and apply insect repellent that includes DEET, picaridin or oil of lemon eucalyptus according to label instructions. Consult a physician before using repellents on infants.
• Make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut, especially at night.
• Change water in birdbaths weekly. Properly maintain wading pools and stock ornamental ponds with fish. Cover rain barrels with 16-mesh wire screen. In communities where there are organized mosquito control programs, contact your municipal government to report areas of stagnant water in roadside ditches, flooded yards and similar locations that may produce mosquitoes.
