The Utah County Health Department has confirmed a human case of West Nile virus, the first in the county since 2017.
The department released no further details.
Several people around the state have been infected with West Nile virus this summer — in Salt Lake, Grand, Uintah and Washington counties. There have been no fatalities.
The virus also has been detected in mosquitoes in Box Elder, Davis, Sevier and Weber counties.
Symptoms of West Nile appear 3 to 14 days after a bite from an infected mosquito. The symptoms include fever, headache and body aches, according to the health department. Severe infections — which can result in debilitating long-term complications or death — may bring high fever, neck stiffness, disorientation, coma, tremors and convulsions.
The health department recommends draining standing water; avoiding being outside at dawn and dusk; wearing long sleeves and pants outside; using insect repellent that contains DEET; and making sure door and window screens are in good repair.
