West Nile Virus found in mosquito traps in Lewiston, Newton, Amalga, Richmond, Wellsville, Trenton, Benson, Hyrum and Mendon.

LOGAN — Mosquito samples collected in Cache County have tested positive for West Nile virus, the Cache Mosquito Abatement District announced Friday.

The positive samples were found in mosquitoes from Amalga, Trenton, Lewiston, Richmond, Wellsville, Newton, Benson, Hyrum and Mendon.

The update came the same day the Bear River Health Department confirmed two human cases of the virus in Cache Valley. Symptoms can range from a mild, flu-like illness to more severe neurological problems in rare cases.

In response, the district said it will continue its surveillance and abatement efforts. The primary method of control is larviciding, which targets mosquito larvae. Fogging will be conducted at night, when the Culex mosquitoes, known carriers of the virus, are most active.
