SPRINGFIELD, IL – Six additional human cases of laboratory positive West Nile virus illness from the Chicago area were reported today by the Illinois Department of Public Health bringing the state's total this year to 217.

Dr. John R. Lumpkin, state public health director, also announced the state has provided an additional $165,439 in emergency funding for mosquito control to four local health departments – East Side Health District ($8,400), Jackson County Health Department ($37,700), Montgomery County Health Department ($95,500) and the Springfield Department of Public Health ($23,839).

Last week, Governor George H. Ryan announced $567,879 in emergency state monies for mosquito abatement efforts to the first three recipients – DuPage County Health Department ($397,160), Shelby County Health Department ($16,000) and the Will County Health Department ($154,719).

Local health departments in areas where there has been a human case of West Nile virus illness and the county or municipality has exhausted its mosquito control resources are eligible for these special state funds.

"We continue to take all possible steps to address this outbreak," Dr. Lumpkin said. "As we have repeatedly reminded people, however, the most effective way to reduce the risk of West Nile virus illness is to follow the precautions that have been recommended, such as using repellent and doing the simple things that can be done to avoid mosquito bites."

Precautions that have been suggested include –

• Avoid being outdoors at dawn, dusk and early evening when mosquitoes are most active. If outdoors at these times, wear shoes and socks, long pants and a long-sleeved shirt to cover as much of the skin as possible. Loose-fitting, light colored clothing is best.
• Use insect/mosquito repellent containing 25 percent to 35 percent DEET when outdoors when mosquitoes are biting, applied sparingly to exposed skin or clothing, as indicated on the repellent label. Consult a physician before using repellents on young children.
• Check for and repair any holes or tears in residential screens, including porches and patios.
• Eliminate stagnant water in bird baths, ponds, flower pots, wading pools, old tires and any other receptacles in which mosquitoes might breed.

The cases reported today were from Chicago (2) and suburban Cook County (4).

SUBURBAN COOK COUNTY: A 72-year-old man from northern Cook County, who was hospitalized with West Nile encephalitis; a 49-year-old man from northern Cook County, whose hospital information is not known; an 80-year-old woman from southern Cook County, who was hospitalized; and an age unknown man from southern Cook County, whose hospital information is not known.

Human cases have been identified in Chicago and 21 Illinois counties: Chicago (49), Clinton County (1), suburban Cook County (120), Crawford County (1), DeKalb County (1), DuPage County (9), Effingham County (3), Ford County (1), Jackson County (2), Kane County (1), Lake County (1), LaSalle County (3), Macoupin County (1), Madison County (4), Montgomery County (1), Moultrie County (1), Sangamon County (1), Shelby County (1), Stark County (1), Stephenson County (1), St. Clair County (6) and Will County (8).

A complete listing of the positive birds, mosquito batches, horses and humans identified so far in Illinois, by county, is available on the Department's Web site at <www.idph.state.il.us>. Go to the West Nile virus page and select "2002" under surveillance.

Dr. Lumpkin said most people who get infected with West Nile virus have either no symptoms or mild symptoms, but a few individuals may develop a more severe form of the disease, such as encephalitis or meningitis.

A total of 476 birds, 451 mosquito batches and 62 horses in 92 Illinois counties have tested positive this year for the virus since surveillance for the mosquito-transmitted virus began on
May 1.

The Culex or house mosquito, which can carry West Nile virus or St. Louis encephalitis virus, breeds in warm, stagnant water and begins to increase in numbers early in the summer. Hot, humid weather conditions in recent weeks have been ideal for breeding the Culex mosquito and, as a result, there has been a jump in the number of positive birds, horses and mosquitoes.

Hospitals and infectious disease physicians have been notified of the increase in detection of humans, birds, mosquitoes and horses with West Nile virus and reminded to order tests for arbovirus infections for patients with appropriate symptoms.

Most people infected with West Nile virus have no clinical symptoms of illness, but some may become ill three to 14 days after the bite of an infected mosquito. Infections can be mild and include fever, headache and body aches, or severe and marked by headache, high fever, neck stiffness, stupor, convulsions, muscle weakness, paralysis and, rarely, death. West Nile virus illness in Illinois has been reported in people ranging in age from 2 to 92, but serious illness is most often present in individuals 50 years of age or older.
