Bird Tests Positive for West Nile
Champaign County Receives Its First Confirmed Case of West Nile Virus in 2010
Champaign, IL – A crow collected by the Champaign County Health Department tested positive for the West Nile virus. The bird was collected outside the city limits on the west side of Champaign on July 13, 2010. “Birds testing positive for West Nile virus serve as a reminder that mosquitoes are active and people should protect themselves against mosquitoes,” said Jim Roberts, Director of Environmental Health.
To date, there have been no human cases reported in Champaign County and no mosquito batches have tested positive for West Nile virus. Mosquito batches or birds testing positive for West Nile virus have been reported in 14 other counties.
Last year, 36 of the state’s 102 counties were found to have a West Nile positive bird, mosquito, horse or human case. A total of five human cases of West Nile disease were reported in Illinois last year. In hotter summers, such as 2005 and 2006, more human cases were reported:
- 2008 – 20
- 2007 – 101
- 2006 – 215
- 2005 – 252
- 2004 – 60
- 2003 – 54
Surveillance for West Nile virus in Illinois began on May 1 and includes laboratory tests on mosquitoes, dead crows, blue jays, robins, and other perching birds as well as the testing of sick horses and humans with West Nile-like disease symptoms. Citizens who observe a sick or dying crow, blue jay, robin or other perching bird should contact their local health department, which will determine if the bird will be picked up for testing.
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 15 days after the bite of an infected mosquito. The first human case in Illinois is not usually reported until July or later.
Only about two people in 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.
- When outdoors, wear shoes and socks, long pants and a long-sleeved shirt, and apply insect repellent that includes DEET, picaridin, oil of lemon eucalyptus or IR 3535 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.
- Eliminate all sources of standing water that can support mosquito breeding, including water in bird baths, ponds, flowerpots, wading pools, old tires, and any other receptacles. 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.
Public health officials believe that a hot summer could increase mosquito activity and the risk of disease from West Nile virus.
