West Nile Virus

West Nile virus (WNV) is a virus commonly found in Africa, West Asia, and the Middle East . WNV is carried by mosquitoes. It can cause disease in humans and animals. The virus was found in the U.S. in 1999 and in Utah in August 2003.

The most common way to get infected is through a mosquito bite. Most people won’t know they are infected as they will not develop any symptoms. For more information on West Nile Virus, please visit our Mosquito Abatement page or the Utah Department of Health.
