Jacksonville, FL - March 5th, 2026 - Florida health officials are issuing a statewide alert regarding the increased detection of mosquitoes carrying West Nile Virus (WNV). The Florida Department of Health (FDOH) reports that infected mosquitoes have been identified in numerous counties, raising concerns about potential transmission as warmer weather approaches. With spring officially underway, and forecasts predicting higher than average rainfall for much of the state, the risk of contracting WNV is expected to escalate.

Understanding West Nile Virus and its Spread

West Nile Virus is a mosquito-borne illness that can affect humans, birds, horses, and other mammals. The virus is primarily spread through the bite of infected mosquitoes. Mosquitoes become infected when they feed on birds carrying the virus, and subsequently transmit it to humans through bites. While not directly contagious from person to person, the increasing prevalence of infected mosquitoes presents a public health challenge. The FDOH emphasizes that increased mosquito activity is directly correlated to warmer temperatures and increased rainfall - conditions currently prevalent and predicted to continue throughout the spring and summer months.

Symptoms and Severity of Infection

The good news is that the vast majority - roughly 80% - of individuals infected with West Nile Virus experience no symptoms whatsoever. These asymptomatic cases are important to note, however, as these individuals can still contribute to the virus's spread without even realizing they are infected.

Approximately 20% of those infected will develop what is known as West Nile fever. Symptoms typically appear between 2 and 14 days after being bitten by an infected mosquito and include:

• Fever: A temperature of 100.4?F (38?C) or higher.
• Headache: Often severe and persistent.
• Body Aches: Muscle and joint pain, causing general discomfort.
• Skin Rash: A rash, typically appearing on the trunk of the body.
• Fatigue: A feeling of extreme tiredness and weakness.

While West Nile fever is generally mild and resolves on its own, it's important to seek medical attention if symptoms develop, particularly if they worsen. The most serious, though thankfully rare, manifestation of WNV is neuroinvasive disease, affecting less than 1% of those infected. This can lead to encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes surrounding the brain and spinal cord). Neuroinvasive disease can result in long-term neurological complications, paralysis, and, in severe cases, death.

Proactive Prevention: Protecting Yourself and Your Community

The FDOH urges all Florida residents to actively participate in mosquito control and personal protection measures. These preventative steps are critical in minimizing the risk of contracting West Nile Virus. Key recommendations include:

• Insect Repellent: Apply insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus, or para-menthane-diol to exposed skin and clothing. Follow the manufacturer's instructions carefully. Remember that repellents don't eliminate the risk entirely, but significantly reduce it.
• Protective Clothing: When outdoors, especially during dawn and dusk - peak mosquito activity times - wear long-sleeved shirts and long pants. Light-colored clothing is also recommended, as mosquitoes are more attracted to dark colors.
• Eliminate Standing Water: This is perhaps the most crucial step. Mosquitoes breed in stagnant water, even in small amounts. Regularly empty and scrub containers that hold water, such as flower pots, birdbaths, pet bowls, and tires. Ensure gutters are clear and water drains properly. Consider using mosquito dunks in water features that cannot be emptied.
• Window and Door Screens: Ensure all windows and doors have screens in good repair to prevent mosquitoes from entering your home.

Looking Ahead: Ongoing Surveillance and Research

The FDOH continues to monitor mosquito populations and WNV activity throughout the state. Data collected helps inform public health strategies and allows for targeted interventions in areas with higher risk. Ongoing research focuses on developing more effective mosquito control methods and potential vaccines for WNV. Citizens are encouraged to report unusually high mosquito activity to their local county health department.
