THREE WEST NILE DISEASE CASES REPORTED
SPRINGFIELD, Ill. - Dr. Eric E. Whitaker, state public health director, today announced three new cases of West Nile disease, including the first two cases in Chicago, have raised the total number of human cases in Illinois this year to 13.
Dr. Whitaker said the latest cases are -
The 13 cases of West Nile disease this year have been from the city of Chicago (2) and Champaign, suburban Cook, DuPage, LaSalle, Macon, Macoupin, Piatt, Sangamon (3) and -more- add 1 Whiteside counties. In 2002, Illinois led the nation in West Nile disease cases with 884 and 66 deaths and, as of this date last year, the state had counted 346 human cases of West Nile disease and 14 deaths.
Dr. Whitaker has encouraged people to take simple, common sense precautions to avoid mosquito bites and protect themselves from West Nile disease. He also reminded Illinoisans that the mosquito season continues until there is a sustained, hard frost, which usually occurs in late October.
The suggested precautions include:
Dr. Whitaker said -- while there is reason for concern -- few people (about 1 in 150) will develop serious illness, even if bitten by an infected mosquito.
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 -more- add 2 some may become ill three to 14 days after the bite of an infected mosquito.
Dr. Whitaker said infections can be mild and include fever, headache and body aches, or can be severe and marked by headache, high fever, neck stiffness, stupor, convulsions, muscle weakness, paralysis and, in rare cases, death. Serious West Nile virus illness is most often present in individuals 50 years of age or older.
A total of 139 birds, 244 mosquito pools and 10 horses have tested positive in 2003 for West Nile virus in 57 Illinois counties since surveillance for the mosquito-transmitted virus began May 1. Last year, West Nile activity was reported in 100 of the state's 102 counties.
West Nile virus has been detected in 44 states in 2003 and more than 3,300 human cases have been reported in 37 states, including Illinois.
In Illinois, the mosquito-borne disease was first confirmed in birds in September 2001 and the state's first-ever human case was reported in August 2002.
The Culex or house mosquito, which can carry West Nile virus or the St. Louis encephalitis virus, breeds in warm, stagnant water and increases in numbers early in the summer.
