West Nile Virus Found in Madison County Mosquitoes

Tuesday, September 6, 2022

Elkhorn Logan Valley Public Health Department reports that a mosquito pool tested positive for the West Nile virus. The infected mosquito pool was collected from a trap in Madison County which was collected on August 23rd as part of the department’s ongoing mosquito surveillance efforts.

Elkhorn Logan Valley Public Health Department asks for the area’s assistance in preventing mosquitoes, including:

Remove Standing Water

Keep mosquitoes from laying eggs inside and outside of your home. These actions can help reduce the number of mosquitoes around areas where people live. Empty and scrub, turn over, cover, or throw out containers that can hold water, such as vases, pet water bowls, flowerpot saucers, discarded tires, buckets, pool covers, birdbaths, trash cans and rain barrels. Any container left outside that can hold water can become a place where mosquito larvae can live.

Improve Sanitation

When water is contaminated with organic matter (for example, animal waste, grasses, and leaves), the chances that mosquito larvae will survive may increase because contaminated matter provides food for larvae to eat.

Protect Yourself

Use an insect repellent containing DEET or Picaridin on skin not covered by clothing:

 

  • Spray insect repellent on the outside of your clothing (mosquitoes can bite through thin clothing).
  • Insect repellents should not be used on young infants.
  • Wear long-sleeved shirts, long pants and socks to protect exposed skin during dusk and dawn, which is when mosquitoes are active.
  • Use air conditioning or make sure there are screens on all doors and windows to keep mosquitoes from entering the home.

According to the Centers for Disease Control and Prevention (CDC), the West Nile Virus (WNV) is usually spread to people by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes then spread West Nile virus to people and other animals by biting them.

Cases of WNV occur during mosquito season, which starts in the summer and continues through fall. There are no vaccines to prevent or medications to treat WNV in people. Most people infected with WNV do not feel sick. About 1 in 5 people who are infected develop a fever and other symptoms such as headache, body aches, joint pains, vomiting, diarrhea or rash. About 1 in 150 people who are infected develop a severe illness affecting the central nervous system such as encephalitis (inflammation of the brain) or meningitis (inflammation of the membranes that surround the brain and spinal cord).

Severe illness can occur in people of any age; however, people over 60 years of age are at greater risk for severe illness if they are infected (1 in 50 people). People with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and people who have received organ transplants, are also at greater risk.
