West Nile Virus Activity in Utah - 2005
Utah’s first West Nile virus (WNV) associated death was re-ported by TriCounty Health Department. This person was over 65 years of age and was a resident of Uintah County. As of October 15, 52 human WNV cases have been report-ed to the Utah Department of Health. Human WNV infections were reported from the following counties: 1 Weber, 14 Uintah, 16 Utah, 7 Duchesne, 6 Salt Lake, 1 San Juan, 1 Carbon, 1 Weber and 6 Washington.
Additionally, two potential blood donors were found to have WNV infection. These blood donations were destroyed to prevent them from entering Utah’s blood supply. So far in 2005, 16 Utah counties have reported WNV activity. 
WNV risk will decrease with onset of fall and cool weather, but may continue longer in Southern Utah.
