WACO, Texas (RFD-TV) — Texas horse owners are being urged to take immediate precautions after state veterinarians confirmed cases of Equine Herpesvirus Type 1 (EHV-1) linked to the WPRA World Championship Barrel Racing Finals held in Waco earlier this month. The outbreak involves an aggressive strain that spreads quickly, prompting Commissioner Sid Miller and the Texas Department of Agriculture to issue an industry-wide alert.
Initial reports indicate multiple horses connected to the Waco event—and animals that later mingled with them—may have been exposed. EHV-1 can cause respiratory illness, neurological impairment, and pregnancy loss in mares, making early detection essential. Because the virus spreads through direct nose-to-nose contact and indirectly via shared equipment or human carriers, state officials warn that even subtle signs such as fever or lethargy must be treated seriously.
Regions surrounding Waco, traveling ropers, multi-barn events, and any facilities that recently hosted large gatherings face elevated risk. Veterinarians recommend isolating exposed horses for at least 14 days, suspending hauling or showing, disinfecting trailers and tack, monitoring temperatures twice daily, and immediately reporting fever or neurologic symptoms.
Looking ahead, the state will continue tracking potential spread while urging all equine operations—large and small—to tighten biosecurity until the incident is fully contained.
Commissioner Miller joined us on Tuesday’s Market Day Report to provide the latest details on the situation and offer guidance for those who may be affected.
In his interview with RFD-TV News, Commissioner Miller outlined what officials currently know about the outbreak, explaining how the virus was detected and what steps state authorities are taking to contain its spread. He also discussed the potential impact the virus could have on the broader equine industry, noting that disruptions to training schedules, competitions, and interstate movement could follow if the outbreak is not quickly controlled. Protecting animal health, he said, is crucial to safeguarding the economic stability of Texas’s robust horse sector.
Miller also reviewed the key symptoms horse owners should watch for, including changes in behavior, respiratory issues, fever, or other signs of distress. Prompt attention, Miller noted, can make a significant difference in preventing further spread, and emphasized the importance of early reporting and cooperation from horse owners across the region.
As for prevention, Miller urged owners to strengthen safety protocols — including limiting contact between horses, disinfecting equipment, isolating new arrivals, and avoiding unnecessary travel. These steps, he said, are essential during any heightened disease risk.
