Equine Herpesvirus (EHV) Update for Our Equine Clients:
We wanted to share some helpful information due to recent reports of an EHV outbreak. A strain of EHV-1 was identified in early November 2025 and was linked to the championship barrel racing finals in Waco, Texas. Since then, additional positive cases have been reported in Oklahoma and Louisiana.
At this time, there are no confirmed cases of EHV-1/EHM in North Carolina.
We simply encourage awareness and caution, especially for horses that travel or show.
How EHV Spreads
EHV can spread through:
• Direct nose-to-nose contact
• Coughing or aerosolized droplets
• Contaminated surfaces (tack, buckets, shared equipment)
• Clothing, hands, and boots of handlers
Signs to Watch For

• Nasal discharge
• Depression or lethargy
• Enlarged lymph nodes
Neurological Form (EHM):

• Hind-end weakness or wobbliness (ataxia)

Pregnant mares may also experience:
