A horse health crisis is unfolding, and it’s time to sound the alarm! We’re talking about an outbreak of equine herpesvirus myeloencephalopathy (EHM), a serious neurological condition affecting horses across multiple states. The source? The Women’s Professional Rodeo Association (WPRA) World Finals and Elite Barrel Race event in Waco, Texas, from November 5th to 9th.
As of November 23rd, the Equine Disease Communication Center (EDCC) has confirmed a staggering 27 cases of EHV-1, the virus responsible for EHM, linked to this event. These cases have spread far and wide, impacting horses in Texas, Oklahoma, Louisiana, Colorado, New Mexico, Washington, and Arizona.
But here’s where it gets controversial…
In Texas alone, we’re seeing a diverse range of outcomes. From McLennan County, where two horses have tested positive and are quarantined, to Wharton County, where one horse has EHM and nine others have been exposed, the impact is widespread. In Bell County, a horse arrived at a veterinary hospital, only to become recumbent within an hour and be euthanized after 48 hours. These stories highlight the devastating impact of this outbreak.
Oklahoma and Louisiana are also battling this virus. In Oklahoma, Logan County has two quarantined horses, while in Louisiana, three horses are receiving treatment at LSU Veterinary Hospital.
And this is the part most people miss: EHV-1 is highly contagious and can cause a range of issues, from respiratory diseases in young horses to abortions in broodmares. The signs are often subtle, with fever being the primary indicator, which can easily go unnoticed.
So, what can we do to protect our equine friends?
The EDCC Health Watch, an Equine Network initiative, emphasizes the importance of routine biosecurity measures. This includes simple practices like hygiene, cleaning, and disinfection to prevent disease spread. Current EHV-1 vaccines may reduce viral shedding but are not a guarantee against the neurological form of the disease.
Prevention is key, and that’s where EDCC Health Watch comes in. By providing open access to infectious disease information, they aim to empower horse owners and enthusiasts with the knowledge to keep their horses safe.
