Health Officials Confirm West Nile Virus-Related Death in Utah
FARMINGTON, Utah — Health authorities in Davis County have reported that one individual has died after contracting a neuroinvasive form of West Nile Virus. This marks the first confirmed death related to the virus in Utah for the year 2025.
The Davis County Health Department has confirmed three cases of West Nile Virus, with two being neuroinvasive. Both hospitalized patients experienced severe symptoms, with one unfortunately passing away as a result of the infection.
Trevor Warner, a spokesperson for the Davis County Health Department, noted in a media statement that while most individuals infected with West Nile Virus do not show symptoms, the virus can lead to mild or severe illnesses in some. “It’s estimated that less than 1% of those infected will develop the neuroinvasive form, which can lead to serious long-term issues or even death,” he said.
Details on Symptoms and Risks
Symptoms of West Nile Virus infection typically manifest within two to 14 days following a mosquito bite and may include fever, headaches, or body aches. More severe cases can involve high fevers, neck stiffness, disorientation, and even muscle weakness.
While those over 60 and individuals with weakened immune systems are particularly vulnerable to illness from the virus, Warner emphasized that anyone can be affected by a bite from an infected mosquito. The specific age or health status of the deceased individual has not been disclosed.
As of August 30, 2025, the Utah Department of Health has reported a total of 16 cases of West Nile Virus in the state, with 13 of those cases being neuroinvasive. Apart from the one fatality in Davis County, there have been no other reported deaths.
The Davis County Health Department is advising anyone who suspects they might have a West Nile Virus infection to reach out to their healthcare provider.
Residents are also urged to take preventive measures against mosquito bites, such as using repellent, wearing light-colored and loose-fitting clothing during evening hours, and minimizing outdoor activities at dawn and dusk when mosquitoes are most active.
To reduce mosquito breeding, Utahns should eliminatestanding water in their yards, keep gutters clear of debris, and maintain short grass and weeds.
