Cache County reports first West Nile case of 2026, prompting mosquito precautions
Health officials in Cache County have confirmed the first human West Nile virus case of the 2026 season. The Bear River Health Department did not release details on the patient to protect privacy. West Nile is spread by infected mosquitoes, with most people showing no or mild symptoms, while a small number can develop severe neurological illness. Mosquito abatement teams across Box Elder, Cache, and Rich counties are monitoring activity and testing traps, with updates on the health department site. Residents are urged to follow the 5 Ds of mosquito prevention: drain standing water, avoid dawn/dusk outdoors, use DEET or approved repellents, wear long sleeves/pants, and ensure window screens are intact. Seek medical attention promptly if severe symptoms such as high fever, neck stiffness, confusion, or muscle weakness occur after a bite.
