Mosquitoes are more than just a nuisance—they can spread diseases that pose serious health risks. In Connecticut, mosquitoes can carry viruses like West Nile Virus (WNV), Eastern Equine Encephalitis (EEE), Jamestown Canyon Virus, and Zika Virus. Taking steps to protect yourself and your community can help prevent these illnesses.

Mosquitoes Can Spread West Nile Virus

West Nile Virus is the most common mosquito-borne disease in Connecticut. Many people infected show no symptoms, but about 20% may develop mild symptoms such as fever, headache, body aches, and occasionally a rash. In rare but severe cases—particularly among older adults and people with weakened immune systems—WNV can cause neurological illnesses like encephalitis or meningitis. These conditions can have long-term effects or be fatal.

As of now, a mosquito in Bridgeport has tested positive for West Nile Virus. However, there have been no reported human cases in the city. Continued precautions are strongly encouraged to prevent transmission.

How to Protect Yourself from Mosquito Bites

• Use Bug Spray: Apply insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus. Follow label instructions and reapply as needed.
• Wear Long Clothes: At dawn and dusk, when mosquitoes are most active, wear long sleeves, pants, and socks. You can also treat clothing with permethrin.
• Use Screens: Ensure your windows and doors have intact screens to keep mosquitoes outside.

Reducing Mosquito Breeding Sites

• Get Rid of Standing Water: Empty and clean items that collect water like bird baths, flower pots, and pet bowls.
• Clean Gutters: Keep gutters clear to avoid water accumulation.
• Maintain Water Features: Add fish to ponds that eat mosquito larvae or use mosquito dunks to prevent mosquito growth.

Protecting yourself and others helps reduce the spread of mosquito-borne diseases in our community.
