Confirmation of West Nile Virus infection in Kentucky prompts advisory for locals to practice safety measures
Headline: West Nile Virus Prevention Advice for Louisville Residents in 2025
In the face of a heightened West Nile virus (WNV) season, health authorities in Louisville and across the United States are urging residents to take precautions to protect themselves from mosquito bites. The Louisville Metro Department of Public Health and Wellness, along with the U.S. Centers for Disease Control and Prevention (CDC), have issued guidelines to minimise the risk of WNV infection.
Body:
People with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and those who have received organ transplants, are at greater risk for serious illness if they contract WNV. However, it's important to note that these guidelines are not new advice from Louisville's Chief Health Strategist Connie Mendel regarding mosquito bite prevention.
The CDC notes that between 1999 and 2024, Kentucky has had 223 confirmed human cases of West Nile. In 2025, the Louisville Metro Department of Public Health and Wellness has confirmed a case of WNV in a Louisville resident, marking the first confirmed human case of West Nile virus in Kentucky for the year.
To prevent WNV, it's recommended to take extra care during peak mosquito-biting hours of early morning and dusk. It's also crucial to eliminate standing water sources around homes where mosquitoes breed, such as birdbaths, flowerpots, pet dishes, wading pools, abandoned tires, and other containers. This should be done on a weekly basis.
The CDC advises the use of EPA-approved insect repellents containing active ingredients such as DEET, picaridin, oil of lemon eucalyptus, IR3535, para-menthane-diol, or 2-undecanone. These repellents provide longer-lasting protection. It's essential to follow label instructions carefully for safe and effective use.
Wearing protective clothing like light-colored, loose-fitting long sleeves, long pants, socks, and shoes can reduce skin exposure to mosquitoes, especially during peak mosquito activity periods from dusk to dawn. Installing or repairing screens on windows and doors can also keep mosquitoes outside.
Spraying clothes with repellent containing permethrin or another EPA-registered repellent will give extra protection. However, it's important to note that repellents should not be applied directly to the skin.
Local mosquito control programs, which may include larviciding catch basins and spraying adult mosquitoes based on surveillance data to reduce mosquito populations, are also encouraged.
Particular attention and precautions are advised for high-risk groups, including people over 50, transplant recipients, pregnant women, and individuals with underlying health conditions.
Most people infected with West Nile virus either show no symptoms or relatively mild symptoms. However, serious illness can occur in people of any age, but people over 60 are at the greatest risk for severe disease. If you believe you have West Nile, it's important to contact your healthcare provider.
Staying informed through local health department updates, such as from Louisville Metro Public Health or state agencies, is also recommended. The CDC does not specifically mention the year 2025 in relation to the number of West Nile cases in Kentucky.
In summary, the key prevention strategy is to minimise mosquito bites through repellent use, protective clothing, avoiding peak mosquito times, and eliminating breeding sites combined with community mosquito control efforts. By following these guidelines, residents can help protect themselves and their families from the potential risks associated with West Nile virus.
