Thanks to late season heat and rainfall, August and September are historically when the presence of West Nile virus (WNV) spikes, and this year is no different.
DuPage County has confirmed its first human cases of West Nile virus for 2019, in two adults from northeast Lombard. Surveillance and testing are also showing an uptick in the number of disease-positive mosquito pools across the county.
Take steps to prevent mosquito breeding, mosquito bites and disease transmission by:
- Avoiding outdoor activity at dawn and dusk when mosquito activity is typically highest.
- Wearing an EPA-approved repellent containing DEET, Picaridin, IR3535 or Oil of Lemon Eucalyptus.
- Limiting skin exposure by wearing long pants and long sleeves. Opt for light colored clothing, as mosquitoes are more attracted to dark colors.
- Keeping mosquitoes outside. Use air conditioning to manage indoor temperatures, and always use window and door screens.
- Eliminating standing water sources. Without a water source, female mosquitoes cannot lay their eggs.
