"West Nile virus is something we've been seeing in Illinois every year since 2001," said Dr. Whitaker. "As counties begin to report their first positive test results for West Nile virus this year, people should brush up on how to protect themselves from mosquitoes."

The only other positive mosquito samples collected so far this year in Illinois have been in DuPage County on May 7.

In 2006, the first positive mosquito sample was reported May 24th in DuPage County. Last year 77 of the state's 102 counties were found to have a West Nile positive bird, mosquito, horse or human case. A total of 215 human cases of West Nile disease, including 10 deaths, were reported last year in Illinois.

Surveillance for West Nile virus in Illinois began May 1st and includes laboratory tests on mosquitoes, dead crows, blue jays, robins and other perching birds as well as the testing of sick horses and humans with West Nile-like disease symptoms. Citizens who observe a sick or dying crow, blue jay, robin or other perching bird should contact their local health department, which will determine if the bird is to be picked up for testing.
