Tooele County has reported one case of West Nile Virus in horses. If you haven’t gotten your horses vaccinated this year, please reach out to our office to schedule or pick up their vaccinations. Animals that have never received any vaccinations are at the highest risk.
The Utah Department of Agriculture and Food (UDAF) is urging all horse owners to vaccinate their animals against West Nile virus (WNV) following confirmed cases across the state. To date, horses in the following 11 counties have tested positive for WNV: Utah (5), Box Elder (3), Cache (3), Weber (2), Davis (1), Uintah (1), Salt Lake (1), Rich (1), San Juan (1), Tooele (1), and Summit (1). Of the confirmed cases, 14 horses have been treated and 6 were euthanized.
“Vaccination is the most effective way to protect horses from West Nile virus,” said State Veterinarian Dr. Amanda Price. “The vaccines are safe, low cost, and provide strong protection, while treatment for infected horses can be very expensive and does not guarantee recovery.”
