📣 Equine Health Update: EHM Outbreak Awareness
Herpes happens, and every year we expect to see some cases of Equine Herpesvirus (EHV). Many of you have seen reports of a developing outbreak of Equine Herpesvirus Myeloencephalopathy (EHM) connected to events in Texas and Oklahoma.
We want our clients to know:
🐴 We are actively monitoring the situation.
Our veterinarians are in close communication with the Pennsylvania State Veterinarian and we are monitoring for new information as it becomes available.
🐴 What’s currently known:
This issue primarily involves Quarter Horses that attended one or more of the three events in TX/OK, or horses that have since had direct contact with horses from those events.
🐴 Good biosecurity is always the best protection.
Regardless of any specific outbreak, all horse owners should consistently follow basic biosecurity practices, including:
- Avoiding shared equipment unless fully disinfected
- Not letting horses touch noses with unfamiliar horses
- Monitoring temperatures daily when traveling or showing
- Isolating new or returning horses for a minimum of 2 weeks
- Contacting your veterinarian if you notice fever, nasal discharge, or any neurological signs
🐴 Please don’t spread rumors.
For accurate, verified updates, rely on reputable sources such as the Equine Disease Communication Center (EDCC): https://www.equinediseasecc.org/
