MOSQUITOES TEST POSITIVE FOR WEST NILE VIRUS
According to Cyndy Howard, Environmental Health Director for the Montgomery County Health Department, routine mosquito testing has identified mosquito samples testing positive for West Nile
Virus.
Positive mosquito samples for 2026 have been collected in Nokomis on July 10th; Farmersville on July 15th, 20th and 22nd; Taylor Springs on August 3; and Witt on July 17th.
This frequent West Nile Virus activity serves to remind us that precautions should be taken to eliminate mosquito breeding areas
and to protect ourselves from mosquito bites while outdoors.
Montgomery County Health Department encourages individuals to report potential breeding sites throughout the county so they may be investigated and treated if necessary. In communities where there are organized mosquito control programs, reports may be made to your local municipality hall. Otherwise potential breeding sites may be reported to the Montgomery County Health Department. Limited supplies of Bti Briquettes are available from the health department for county residents to treat their own
properties.
West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Only about two persons out of every ten who are bitten by an infected mosquito will experience any illness.
Illness from West Nile disease normally occurs three to 14 days after the bite of an infected mosquito and is usually mild and includes fever, headache and body aches.
However, serious illness such as encephalitis and meningitis, with lingering complications and even death, are possible. Persons older than 50 years of age have the highest risk of severe disease.
Montgomery County Health Department has been conducting an annual West Nile virus surveillance program since May that includes trapping adult mosquitoes and testing them for the West Nile virus. The health department is not collecting dead birds for 2026; however birds that have recently died from unknown causes can still be reported to the health department for monitoring purposes. Persons who observe a sick or dead crow, blue jay, robin or other perching bird may contact the health department at
217-532-2001.

West Nile virus emerged in the United States in the New York metropolitan area in the fall of 1999. Since then, the virus, which can be transmitted to humans by the bite of an infected mosquito, has quickly spread across the country.
