West Nile Virus Found in Tippecanoe County

A mosquito pool sampled in Tippecanoe County has tested positive for the West Nile virus, according to local health officials. This marks the first confirmed instance of the virus detected in a mosquito sample collected in the county on July 15, 2026. Health authorities stated that this finding is not entirely unexpected, as West Nile virus has been a recurring presence in the region for several years.

Data indicates that two mosquito pools, totaling 69 mosquitos, have been tested in Tippecanoe County so far this year. In the previous year, 2025, four out of six tested pools in the county were found to be positive for the virus. Currently, no surrounding counties have reported positive samples.

West Nile virus, transmitted to humans through mosquitos that have bitten infected birds, can cause severe illness in rare cases. Symptoms may include high fever, headache, stiff neck, confusion, muscle weakness, or paralysis, though most infected individuals experience mild or no symptoms. Health officials recommend preventative measures, such as using insect repellent containing DEET and ensuring properties are free of standing water, which serves as a breeding ground for mosquitos, especially during peak activity hours from dusk through dawn.
