There have been three human cases of West Nile Virus in California this year, with one fatal case, according to the California Department of Public Health.

Mosquitoes carrying West Nile virus have been detected in Cache County weeks earlier than usual. Residents are being encouraged to protect themselves from bites as the virus spreads across northern Utah.

The person who died was identified as an older adult with underlying health conditions. So far this year, 17 human cases of West Nile have been confirmed in the county.
