Mosquitoes test positive for West Nile virus in DuPage towns

The DuPage County Health Department announced Monday the first mosquito batches to test positive for West Nile virus this year.

The first virus-positive pools of mosquitoes were collected in Roselle, Glendale Heights and Wheaton on May 12.

So far, there have been no reported human cases of the virus in DuPage. However, the identification of positive mosquito pools is associated with an increased risk of West Nile in people.

The county health department says people should follow the “3 R’s” to protect themselves: Reduce the number of mosquitoes by removing containers outside that hold water; repel mosquitoes by using insect repellent; and report stagnant water or other concerns through its website.
