NASHVILLE, TENN. (RFD-TV) — Horse owners across the southwest are on alert after an outbreak of Equine Herpesvirus Type 1 (EHV-1). The virus first appeared following events in Texas and Arizona, and some horses have already died.
Veterinarians say it spreads quickly through contact, shared equipment, trailers, and even human clothing. Exposed horses should be isolated for at least two weeks, and ranches and events are tightening biosecurity. Events, including a Scottsdale roping, have been postponed to protect animals.
Authorities urge owners to stay home, limit travel, and monitor their horses closely to stop the spread.
Texas Ag Commissioner Sid Miller issued an alert earlier this week to Texas horsemen.
“This virus can spread fast, it can be deadly, and the earliest signs are often so subtle they’re easy to miss. That’s why monitoring your horses right now is critical. The quicker we identify a potential case, the better chance we have to protect not only our animals, but the entire Texas equine community.”
