Fight the Bite: Cook County Department of Public Health Urges Residents to Protect Against West Nile Virus

As summer temperatures rise, so does the risk of West Nile virus (WNV), a mosquito-borne illness that can lead to serious health complications. Cook County Department of Public Health (CCDPH) is encouraging residents to take preventive actions to reduce their risk of infection and limit the spread of the virus in the community.

West Nile virus is transmitted to humans through the bite of infected mosquitoes. These mosquitoes become infected after feeding on birds carrying the virus. Many people who contract WNV experience no symptoms, but some may develop fever, headache, body aches, joint pains, vomiting, or rash.

In severe cases, WNV can lead to neurological conditions such as encephalitis or meningitis, which can be life-threatening, especially for older adults and individuals with weakened immune systems.

Residents are encouraged to take the following precautions:

(1) Apply EPA-registered insect repellent to keep mosquitoes away. A repellent containing 20% to 50% DEET is good for adults, and a child-friendly repellent with 20% to 30% DEET is sufficient for children.

(2) Drain standing water around your home. That includes flowerpots, old tires, buckets and plastic wading pools.

(3) Repair torn window screens. Screens should be tight-fitting without gaps.

(4) Beware during dusk and dawn, when mosquito activity is heaviest. Limit time outdoors during this period.
