Weber County joined the growing list of counties that have detected West Nile virus after veterinarians diagnosed the state's first horse to come down with the mosquito-borne disease. The Utah Department of Agriculture and Food reported Thursday that the horse, which had to be euthanized, lived in the Ogden area and had not received a West Nile virus vaccination. A vaccine is available to protect horses and some birds, but there is no such treatment for people. Duchesne, Salt Lake, Uintah, Utah and Weber counties have all reported West Nile virus activity in mosquitoes and animals. No human cases have been reported so far this summer in the state. West Nile mosquitoes are most active between dusk and dawn, when those spending time outdoors should take precautions. The U.S. Centers for Disease Control and Prevention suggest using a repellent with DEET or Picaridin. People should also consider long sleeves and pants. Most people who contract West Nile virus will show no signs of the disease. Symptoms of the mild version of West Nile can include body aches and rash. The disease can result in meningitis and encephalitis. More West Nile virus information is available from the Utah Department of Health, http://health.utah.gov or from the state agriculture department, http://www.ag.utah.gov. - Greg Lavine
