Urgent Alert: EHV-1 Outbreak Affects Rodeos in Live Oak and McMullen Counties
Horse owners are advised to take precautions as EHV-1 spreads.
Live Oak and McMullen County, Texas – Horse owners in Live Oak and McMullen counties are being urged to remain vigilant following a recent outbreak of Equine Herpesvirus Type 1 (EHV-1). This highly contagious virus has led to the cancellation and postponement of several rodeo events in the region, highlighting the need for effective community engagement and proactive measures to safeguard equine health.
The outbreak was initially linked to the Women’s Professional Rodeo Association (WPRA) World Finals and Elite Barrel Race held in Waco, Texas, from November 5–9, 2025. Horses that attended this event have tested positive for EHV-1, prompting health officials to implement strict biosecurity measures to prevent further spread. As of November 23, 2025, 27 cases of EHV-1 associated with the Waco event have been confirmed across multiple states, including Texas, Oklahoma, Louisiana, Colorado, New Mexico, Washington, and Arizona.
Impact on Local Rodeo Events
In response to the outbreak, several rodeo events in Texas have faced cancellations and postponements. Notably, the San Antonio Stock and Rodeo Show canceled its qualifying event in Uvalde, initially scheduled for November 19–22, 2025, due to health concerns surrounding the EHV-1 outbreak. The DeSoto County Pro Rodeo in Mississippi was also postponed to December 12-13, 2025, as a precautionary measure to protect the health of horses and participants alike.
Understanding Equine Herpesvirus Type 1 (EHV-1)
Equine Herpesvirus-1 primarily causes respiratory illness, abortion in mares, and, in severe instances, a neurological condition known as equine herpesvirus myeloencephalopathy (EHM). It spreads through nose-to-nose contact, coughing, sneezing, and contaminated equipment. Horse owners are advised to monitor their animals closely for symptoms such as fever, nasal discharge, coughing, depression, and neurological signs like stumbling or incoordination.
Recommended Biosecurity Practices
In light of the EHV-1 outbreak, the Texas A&M AgriLife Extension Service has released a fact sheet outlining crucial biosecurity practices. Key recommendations include:
- Isolating exposed horses for at least 14 days.
- Avoiding the hauling or showing of horses that may have been exposed.
- Thoroughly disinfecting equipment and facilities.
Horse owners are encouraged to consult with their veterinarians for guidance on vaccination and other preventive measures to bolster their horses’ defenses against the virus.
Importance of Early Detection and Reporting
Health officials emphasize the significance of early detection and reporting to control the spread of EHV-1. Horse owners are urged to contact the Texas Animal Health Commission if they suspect their animals have been exposed to the virus. This proactive communication fosters a collaborative effort to mitigate risk and protect the broader equine community.
Conclusion
As the EHV-1 outbreak develops, horse owners in Live Oak and McMullen counties are advised to stay informed and adhere to recommended biosecurity protocols to safeguard their animals and the wider equine community. Community vigilance and proactive measures can effectively combat this imminent threat. Residents are encouraged to remain engaged in local equestrian events and support initiatives that prioritize public health and well-being.
