Indianapolis, IN, September 9, 2026 —
State health officials have confirmed the detection of West Nile virus (WNV) in mosquito populations across 34 counties in Indiana. The virus has been found in mosquito samples, with the most significant concentrations reported in the northern and Central regions of the state.
In response to these findings, Indiana health authorities are issuing advisories to residents, emphasizing the importance of taking preventative measures against mosquito bites. West Nile virus is known to cause severe illness in some individuals and is transmitted to humans through the bite of an infected mosquito.
To mitigate the risk of infection, residents are advised to implement several protective strategies. These include regularly draining any standing water around homes and properties, which can serve as breeding grounds for mosquitoes. Additionally, covering exposed skin with long-sleeved shirts and pants when spending time outdoors, particularly during dawn and dusk when mosquitoes are most active, is recommended. The use of EPA-registered insect repellents is also suggested as an effective way to ward off mosquito bites.
The specific dates of detection and the exact species of mosquitoes found to be carrying the virus were not immediately available. Health officials continue to monitor mosquito activity and WNV prevalence throughout the state.
