EHV-1 Update: Quarantine Lifted in Clark County

Clark County – The Nevada Department of Agriculture (NDA) has lifted all quarantines for Equine Herpes Virus – Type 1 (EHV-1) in the state. This marks the first time in nearly 8 weeks a facility has not been under quarantine for EHV-1 in Nevada.

One positive case related to an aborted horse was confirmed in Humboldt County, but no quarantine was issued. The NDA reports that the incubation period passed and no horses were moved to or from the property. The infected horse had traveled to a high school rodeo in March in Nevada.

“This case shows how the disease is spread among the equine population,” Dr. JJ Goicoechea, NDA state veterinarian, said. “The mare that aborted was never moved. The virus was brought home from a rodeo on another horse that was exposed, but never showed signs of disease.”

The Nevada State Veterinarian is still urging horse owners to use caution and practice good biosecurity when traveling and competing. Always monitor horses for signs of disease, like fever or runny nose.

Biosecurity means doing everything possible to reduce chances of an infectious disease being transferred by people, animals, equipment or vehicles. EHV-1 and other diseases can be easily transferred on boots, coats, gloves and equipment. Some basic practices include:

  1. Never share equipment between horses, and always wear clean clothes when going from ill horses to others. 
  2. Always start chores at healthy horses, and end with sick or recovering (within 30 days) horses.
  3. Avoid common areas such as hitching rails, wash racks, etc. during an outbreak.
