West Nile Virus Detected in Cache Valley Mosquitoes

HYDE PARK, Cache County — The Utah State Public Health Laboratory has confirmed the presence of the West Nile virus in mosquito samples collected from Cache Valley.

Specifically, mosquito pools from the communities of Amalga and Trenton tested positive for the virus.

As of now, no human cases have been reported in the county.

The Cache Mosquito Abatement District has been notified and is intensifying its abatement efforts, focusing on evening hours when the Culex mosquitoes—known carriers of the virus—are most active.

Residents are advised to take the following precautions to reduce the risk of infection:

Use EPA-Registered Insect Repellents: Apply repellents containing DEET, permethrin, picaridin, IR3535, or oil of lemon eucalyptus as directed.

Eliminate Standing Water: Remove stagnant water from items like old tires, potted plant trays, pet dishes, toys, buckets, and other containers to prevent mosquito breeding.

Wear Protective Clothing: During peak mosquito activity between dusk and dawn, wear long sleeves and pants.

Maintain Property: Keep roof gutters clear of debris, regularly clean or drain swimming pools, ensure window and door screens are intact, and trim tall grass and weeds.

According to the Centers for Disease Control and Prevention, the West Nile virus is the most common mosquito-borne disease in the United States, affecting humans, birds, and horses.

Transmission occurs through the bite of an infected mosquito.

Most individuals infected with the virus experience mild, flu-like symptoms or none at all.

However, severe cases can lead to serious health complications.

In 2024, Cache County reported its first human case of West Nile virus, highlighting the importance of ongoing vigilance and preventive measures.

Residents are encouraged to stay informed and proactive in protecting themselves and their communities from mosquito-borne illnesses.
