Health Officials Report The First Human Case Of West Nile In Illinois This Year

Andy Novinger, an assistant entomologist with the Northwest Mosquito Abatement District, explains how a gravid mosquito trap works at the district’s facility in Wheeling, Ill., Thursday, May 29, 2003. The trap has a tub of stagnant water, which attracts female mosquitoes, and when the mosquitoes hover over the water, they are sucked into the trap by a battery-powered fan. The district has 14 of these traps set up in various residential areas to collect mosquitoes and test them for West Nile Virus and other mosquito-bourn illnesses.

Health Officials Report The First Human Case Of West Nile In Illinois This Year

It’s usually late July or early August before Illinois has its first human case of West Nile. Health officials say an adolescent in west-central Illinois became severely ill in late May.

Local health officials are quick to point out that the mosquitos that spread the Zika virus are a different breed, known as house mosquitos, and are rarely found in Illinois.

Additional information about West Nile virus can be found on the IDPH website.
