TWO NEW HUMAN CASES OF WEST NILE REPORTED
SPRINGFIELD, Ill. Two new human cases of West Nile disease have been identified in Illinois, bringing to nine the number of cases reported so far this year in the state, Dr. Eric E. Whitaker, state public health director, today announced.
The new cases are:
The other human cases of West Nile disease identified so far this year have been: a 67-year-old man from Jo Daviess County, a 39-year-old Jackson County man, a 14-year-old boy from St. Clair County, a 70-year-old man from Kendall County, a 47-year-old Ford County man, a 59-year-old man from Boone County and a 53-year-old woman from Sangamon County.
In addition to the new human cases, Dr. Whitaker said a blue jay found Aug. 16 in Marissa in Washington County tested positive for West Nile, bringing to 49 the number of counties this year with West Nile activity. A total of 143 birds, 503 mosquito pools, two horses and one alpaca from 49 counties have been identified with West Nile since surveillance for the mosquito-borne disease began May 1.
Dr. Whitaker urged people to continue to take simple, common sense precautions to avoid mosquito bites and protect themselves from West Nile disease. These precautions 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.
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.
