West Nile Virus Alert System

The DuPage Health Department has created a new system called Personal Protection Index (PPI) which will inform residents of the amount of West Nile Virus activity in the area each week. The system uses a number to convey mosquito conditions from 1 (little activity) to 4 (high activity). To learn more about the system, access the Personal Protection Index flyer.

Shown to the right is the Personal Protection Index, which will be updated by the Health Department on a weekly basis.
