VERMONT — A pool of mosquitoes collected in Vermont have been confirmed to have tested positive for the West Nile virus, according to Damon Roberson, administrator for the Fulton County Health Department.
"West Nile virus activity has been present in the state, and we expected to see activity again this year," Roberson said in a news release. "These findings should serve as a reminder to (residents) to take precautions to prevent contracting the mosquito-borne disease."
The mosquitos that tested positive were collected Sept. 4, by Western Illinois University students. The health department, the release states, is working in conjunction with WIU to trap and test mosquitoes in the southwestern area of Fulton County.
Illinois' surveillance for West Nile began May 1 and includes laboratory tests on mosquitoes, dead crows and blue jays, and the testing of sick horses and humans with West Nile-type disease symptoms. Residents with who observe a sick or dying crow or blue jay should contact their local health department, which can determine whether the bird should be sent for testing.
West Nile is transmitted, according to the health department, through the bite of a mosquito that has picked up the virus from 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.
The first human case is not usually reported until July or later.
Only about two people out of every 10 who are bitten by an infected mosquito will experience any illness. Sickness from the virus is typically mild and includes fever, headache or body aches, but serious illness, such as encephalitis and meningitis, and death are possible.
People ages 50 and up have the highest risk of severe disease.
Health department officials recommend prevention of West Nile or any other mosquito-borne illness by any reduction of the number of mosquitos around the home and for individuals to take personal precautions to avoid bites.
Information about West Nile can be obtained by contacting the local health department; in Fulton County, thats's by calling 309-647-1134 from 8 a.m. to 4 p.m. Monday through Friday.
