The Indiana Department of Health confirmed three mosquito pools in Daviess County tested positive for West Nile virus. The Daviess County Health Department urges residents to take precautions against mosquito bites.

Officials say mosquitoes carrying West Nile are most active between dusk and dawn. They recommend using insect repellent, wearing long sleeves and pants, and reducing standing water around homes.

Older adults and those with weakened immune systems are at higher risk of severe illness. More information is available from The Indiana Department of Health.

Officials report that local agencies are increasing mosquito treatment efforts in the areas where the positive samples were found. Health experts remind the public that mosquitoes can also carry other viruses, including Eastern equine encephalitis and La Crosse virus, and that prevention is the best protection.
