As the temperatures rise, so does the risk of mosquito-borne diseases in Oklahoma.
The most common mosquito-borne illness in the state is the West Nile Virus, which can cause serious health complications.
As we head into the warmer months, it’s important to take proactive steps to protect ourselves and our families from West Nile and other vector-borne diseases.
According to the Centers for Disease Control and Prevention (CDC), approximately 1 in 5 people infected with the West Nile Virus will develop symptoms, including fever, headache, swollen lymph nodes, body aches and a rash.
For some, the virus can lead to more severe illness, with 1 in 150 infected individuals potentially developing a fatal condition, such as encephalitis or meningitis.
People over the age of 50 are especially at risk for developing a neurological disease from West Nile Virus.
Symptoms of the virus can appear anywhere from 3 to 14 days after infection.
Contact your healthcare provider if your mosquito bite causes a high fever, severe headache and signs of infection.
Unfortunately, no vaccine is currently available for West Nile Virus, which makes prevention even more essential.
Understanding how to reduce mosquito exposure is the best defense against contracting the virus.
There are several effective measures you can take to minimize your risk of being bitten by an infected mosquito:
- Eliminate Standing Water: Mosquitoes breed in standing water, so empty containers like bird baths, flower pots and clogged gutters where water can accumulate around your home. Empty your pet’s outdoor water bowls and refill them daily.
- Use Insect Repellent: Always wear an EPA-registered insect repellent when spending time outdoors, especially during dawn and dusk when mosquitoes are most active. Use enough repellent to cover exposed skin.
- Wear Protective Clothing: Wear long sleeves and pants to reduce exposed skin when possible.
- Install Screens: Ensure that windows and doors have screens in good condition to keep mosquitoes out.

As we enjoy outdoor activities, it’s important to remain vigilant and protect ourselves from the risks associated with mosquito bites.
