Texas officials confirm a horse in Denton County is positive for the neurologic strain of the equine herpes virus (EHV-1). The barrel racing horse traveled to area events prior to its diagnosis.
The Texas Animal Health Commission states the barrel racing horse showed signs of ataxia, loss of muscle coordination, and other neurologic issues consistent with equine herpes myeloencephalopathy (EHM).
The horse’s premises is quarantined.
The horse attended barrel racing events in two cities prior to its diagnosis on February 21. It went to a barrel race at the NRS Arena in Decatur on February 15 and was at the Northside Arena in Fort Worth on February 14.
State officials contacted event management and veterinarians so participants can be notified. The events are supposed to step-up biosecurity measures at the facilities.
Veterinarians recommend isolating exposed horses as well as taking their temperatures twice daily.
Symptoms that should alert horse owners to the possibility of a neurologic EHV-1 infection include a fever of over 102 degrees, weakness, incoordination, urine dribbling or the inability to urinate.
A veterinarian should immediately examine horses with these symptoms.
