"West Nile virus was detected in mosquitoes collected on July 2, 2019 by the Moab Mosquito Control District in Scott M. Matheson Wetland Reserve. Positive results were referred by the Utah Public Health Laboratory on July 11, 2019.
West Nile virus is transmitted by Culex mosquitoes that bite at night. Peak Culex vector mosquito is within two hours after the first stars appear at sunset.

In addition, Matheson Wetlands are scheduled for aerial larviciding on Sunday, July 14th.
People should avoid mosquito bites after dark by wearing brightly colored long sleeves, long pants, and anti-mosquito substances. Use insect repellents registered by the Environmental Protection Agency (EPA) containing one of the following active ingredients: DEET: Picaridine (known as KBR 3023 and Icaridin outside the United States), IR3535, lemon eucalyptus oil ( OLE), para-menthane-diol (PMD). ), 2-undecanone.

The elimination of stagnant water, such as swimming pools, hot tubs, wading pools, buckets filled with water, livestock waterers and flood-irrigated fields will reduce populations. of mosquitoes.
If a person is infected with West Nile virus, the risk of serious illness is low. Most people affected will suffer from a mild to severe form of influenza, characterized by muscle aches, fever, rashes and headaches that usually lasts a few days but can last for months. In rare cases, infected persons may contract meningitis or encephalitis. The people most at risk of serious illness are those with weakened immune systems, diabetes, high blood pressure or kidney disease. Older people are most at risk of serious complications.
