West Nile Virus Confirmed in Marshall County: What Residents Need to Know

Five mosquito pools in Marshall County have tested positive for West Nile virus, raising concerns among local health officials. Byron Holm, the health officer, emphasizes the importance of taking precautions. “As people enjoy the outdoors, it’s crucial to be aware of the risks of West Nile virus from mosquitoes,” he says.

West Nile virus spreads when mosquitoes bite infected birds. Symptoms can appear up to 15 days after a bite and may include fever, headaches, body aches, swollen lymph nodes, or a rash. In rare cases, it can lead to severe illnesses like encephalitis or meningitis.

Dr. Holm highlights that preventing the virus is possible. He shares practical tips for those spending time outdoors:

• Stay indoors from dusk to dawn, when mosquitoes are most active.
• Use insect repellents with DEET, picaridin, or oil of lemon eucalyptus on exposed skin and clothing.
• Wear long sleeves and pants to reduce skin exposure.

Health officials also recommend actions residents can take to eliminate mosquito breeding sites around their homes:

• Fix broken septic systems.
• Drill holes in outdoor recycling containers to prevent water accumulation.
• Keep grass short and shrubs trimmed.
• Dispose of old tires and containers that can hold water.
• Clean out any water-holding containers weekly.
• Maintain gutters to ensure proper drainage.
• Consider aerating ornamental pools or adding fish that eat mosquito larvae.

While individuals over 50 are at higher risk for severe outcomes, cases of serious illness have occurred in people of all ages. According to a recent study, around 1 in 150 people who become infected can develop these serious conditions.
