Alert ID: 2908
February 16, 2023
Confirmed Case(s) - Official Quarantine

Texas Animal Health Commission

Number Confirmed: 1; 
Comments: The Texas Animal Health Commission (TAHC) received confirmation of equine herpes myeloencephalopathy (EHM), the neurologic disease linked to equine herpes virus (EHV-1), in a Hood County Quarter Horse on February 9, 2023. This is the first positive detection of EHM in Texas this year. The horse was tested after showing neurologic signs, including poor muscle control in the hind limbs. The local veterinary clinic immediately placed the horse in an isolated quarantine where it remains throughout treatment. The premises of origin has been quarantined and TAHC staff are working closely with the owner and local veterinarian to monitor other horses and enforce biosecurity measures on the premises. The EHM positive horse attended the National Western Stock Show rodeo event in Denver, Colorado on January 20-21, 2023, and returned to its premises of origin following the event. The horse has not visited any other events that would expose additional equine. The Colorado State Veterinarian was contacted about this case.
