Las Vegas –Two new horses in Clark County are showing clinical signs of Equine Herpes Virus – Type 1 (EHV-1), according to Nevada Department of Agriculture (NDA) State Veterinarian JJ Goicoechea. In addition, a new positive case in Idaho was at a recent barrel racing event in Utah and may have exposed other horses.
“Two horses in Clark County are being tested today for EHV-1,” Dr. Goicoechea said. “In the meantime, I am recommending, along with my counterparts in Arizona, Idaho, and Utah, that horse owners do not travel to barrel racing events in the region.”
Dr. Goicoechea and state veterinarians in neighboring states continue to monitor in cooperation with horse event and venue managers. At this time, only barrel racing events, a specific rodeo competition event, are included in the recommendation.
“We may issue more recommendations throughout the day and weekend,” Dr. Goicoechea said. “But if you don’t have to travel with your horse this weekend, it’s best to stay home and protect your horse, as well as the rest of the competing horses in the west.”
There have been multiple cases of EHV-1 confirmed in surrounding states in the past week. Most cases are unrelated to each other.
- One horse was euthanized in Yavapai County, Arizona on March 26 after displaying neurological signs.
- One horse tested positive in Maricopa County, Arizona on March 26. It had been in the St. George-Hurricane, Utah area for the “Dixie Classic” at Washington County Legacy Horsepark.
- One horse was euthanized in Alameda County, California on March 26 after displaying severe neurologic symptoms. One barn of exposed horses was placed under quarantine.
- One horse was euthanized in Maricopa County, Arizona on March 28. Other horses in the facility who were exposed have been quarantined.
- One horse showing symptoms in Ada County, Idaho reported on March 29. The horse traveled to the Salty Dash Futurity in South Jordon, Utah in mid-March.
