SEPTEMBER 9, 2022
Bloomington, IL— McLean County Health Department’s (MCHD) Environmental Health Division is reporting the first mosquito pool collected in McLean County to test positive for West Nile Virus this year. The positive test was confirmed on September 9, 2022, from the 61705 zip code area east of Bloomington. MCHD staff immediately began distributing informational doorknob hangers about WNV and preventative measures in the neighborhood where the mosquito pool was collected.
West Nile Virus (WNV) most commonly occurs mid-summer to early fall. It is a mosquito-borne disease that can cause encephalitis - an inflammation of the brain. Infected mosquitoes pass the virus onto birds, other animals, and people. Anyone can get WNV, and 4 out of 5 people will experience no symptoms according to the Centers for Disease Control and Prevention (CDC). However, people aged 50 and older are at greater risk of severe illness.
“Regular mosquito and bird surveillance allows public health officials to track the presence of West Nile Virus in McLean County. When disease-carrying mosquitoes become more active, the risk of human exposure and infection also increases,” said Tom Anderson, Director of MCHD Environmental Health Division. “To avoid human cases of the virus, we recommend everyone in McLean County take measures to fight the bite.”
To “fight the bite” MCHD recommends residents follow the 3 Rs:
As of September 8, 2022, the Illinois Department of Public Health (IDPH) has reported two human WNV cases, one of which resulted in the first WNV death of 2022.
