THIRD ST. CLAIR COUNTY WEST NILE CASE REPORTED

SPRINGFIELD, Ill. – Dr. Eric E. Whitaker, state public health director, today announced a 74-year-old man from LaSalle County has been diagnosed with West Nile encephalitis, bringing to 26 the number of Illinoisans this year identified with the mosquito-borne disease.

Other West Nile diseases cases have been identified in the city of Chicago, and Boone, Clinton (2), suburban Cook (2), DuPage (3), Ford, Fulton, Hancock, Jackson, Jo Daviess, Kane, Kendall, LaSalle, McLean, Rock Island, Sangamon, St. Clair County (3) and Will (2) counties.

The state’s only West Nile fatality this year was a 58-year-old DuPage County man who died Sept. 1.

There have been a total of 26 humans, 200 birds, 882 mosquito pools, two horses and one alpaca from 54 counties that have been identified this year with West Nile virus.

In 2003, Illinois recorded 54 West Nile disease human cases, including one death, and in 2002, the state led the nation with 884 cases and 66 deaths.

Most mosquito-borne infections in Illinois occur in August and September, so Dr. Whitaker again reminded people to continue to take simple, common sense precautions to avoid mosquito bites and protect themselves from West Nile disease. These 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 according to label instructions. Consult a physician before using repellents on young children.
Make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings.
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.

WNV 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 over 50 years of age have the highest risk of severe disease.
