West Nile Virus Detected in Hamilton County Mosquitoes, Fishers Health Officials Urge Precautions

The Fishers Health Department (FHD) is urging residents to take precautions after the Indiana Department of Health confirmed the presence of West Nile Virus (WNV) in mosquito samples collected within Hamilton County.

The detection comes as WNV activity typically spikes between July and September, especially during dawn and dusk hours when mosquitoes are most active. Health officials are advising the public to take preventive measures to protect against mosquito bites and reduce mosquito breeding grounds.

Preventive Recommendations:

  • Eliminate standing water in items such as birdbaths, flowerpots, gutters, and other containers where mosquitoes can breed.

  • Use EPA-registered insect repellents that contain DEET, Picaridin, or Oil of Lemon Eucalyptus.

  • Wear protective clothing including long sleeves and pants, particularly during early morning and evening hours.

  • Ensure window and door screens are intact to prevent mosquitoes from entering homes.

  • Limit time outdoors during dusk and dawn, when mosquitoes are most active.

“West Nile Virus is a serious health concern, especially for people over the age of 50 who are at greater risk for severe illness,” the FHD stated in a public advisory. “While many infected individuals may not show symptoms, some may experience moderate to severe illness.”

West Nile Virus is the leading mosquito-borne disease in the United States. Symptoms can range from mild flu-like illness to severe neurological complications. There is no specific treatment for WNV, making prevention the most effective strategy.

The Fishers Health Department will continue to monitor mosquito activity and work with the state health department to assess risk levels in the community.
