ILLINOIS’ 25th WEST NILE DISEASE CASE REPORTED
SPRINGFIELD, Ill. – Dr. Eric E. Whitaker, state public health director, today announced the 25 th human case of West Nile disease to be reported this year in Illinois is a 48-year-old man from DuPage County who became ill in mid-August with West Nile fever, but did not require hospital treatment.
There have now been three cases of West Nile infection identified in DuPage County, including one death, since surveillance for the mosquito-borne disease began May 1. The state’s only West Nile fatality this year was a 58-year-old DuPage County man who died Sept. 1.
Besides the DuPage County cases, other West Nile diseases cases have been identified in the city of Chicago, and Boone, Clinton (2), suburban Cook (2), Ford, Fulton, Hancock, Jackson, Jo Daviess, Kane, Kendall, LaSalle, McLean, Rock Island, Sangamon, St. Clair County (3) and Will (2) counties.
There have been a total of 25 humans, 199 birds, 879 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:
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 .
