Mosquito Control Awareness Week: Protect Against West Nile Virus
As summer temperatures rise, so does the risk of West Nile virus, a mosquito-borne illness that can lead to serious health complications and, in rare cases, death. In recognition of National Mosquito Control Awareness Week, Cook County Department of Public Health urges residents to take simple, yet effective, steps to protect themselves and their communities from mosquito-borne illnesses.
West Nile virus is transmitted to humans through the bite of infected mosquitoes, which become carriers after feeding on birds carrying the virus. While many individuals infected with West Nile virus may not show symptoms, some may experience fever, headache, body aches, joint pain, vomiting, or rash.
In severe cases, West Nile virus can cause neurological conditions, such as encephalitis or meningitis—especially dangerous for older adults and people with weakened immune systems.
To reduce the risk of infection, residents are encouraged to take the following precautions:
- Apply EPA-registered insect repellent to keep mosquitoes away.
A repellent containing 20% to 50% DEET works well for adults, while a child-friendly repellent with 20% to 30% DEET is sufficient for children.
- Drain standing water around your home.
This includes flowerpots, old tires, buckets, and plastic wading pools—any place where mosquitoes can breed.
- Repair torn window screens.
Ensure screens are tight-fitting and free of gaps.
- Be cautious during dawn and dusk, when mosquito activity is highest.
Limit time spent outdoors during these peak periods.
