Confirmed: West Nile Virus Detected in Mosquitoes in South Louisiana

As we are in the middle of summer, residents of south Louisiana are being urged to take precautions against West Nile Virus following recent tests that detected the virus in mosquitoes in Iberia Parish. The Louisiana Department of Health (LDH) has issued a warning about the increased risk of mosquito-borne illnesses in Acadiana.

West Nile Virus is one of the most prevalent mosquito-borne diseases, and it follows a predictable life cycle during the summer and fall. The cycle begins with an infected mosquito transmitting the virus to birds, which serve as a host. Subsequently, mosquitoes that bite these infected birds can spread the virus to humans and animals.

Approximately 20% of those infected with West Nile Virus experience symptoms such as fever, headache, and rash. However, in some cases, the virus can lead to severe brain infections like meningitis or encephalitis. Last year, Louisiana reported 65 cases of West Nile Virus, including 46 severe neuroinvasive cases, resulting in four deaths.

To prevent the spread of the virus, LDH emphasizes the importance of mosquito bite prevention. Key recommendations include:

- Use EPA-Approved Repellents: Apply insect repellent to exposed skin and clothing, following the product's instructions. If using sunscreen, apply it before the repellent.
- Wear Protective Clothing: Opt for light-colored clothing and long sleeves, especially during dawn and dusk when mosquitoes are most active.
- Eliminate Standing Water: Mosquitoes breed in stagnant water. Regularly check and empty containers such as barrels, planters, wheelbarrows, and buckets. Clean roof gutters and ensure water gardens and ornamental pools do not stagnate.
- Maintain Screens: Ensure that windows and doors are tightly sealed and that screens are intact to prevent mosquitoes from entering homes.

LDH started issuing weekly reports of West Nile Virus cases in the first week of July.
