Montgomery county, TX
Alert ID: 1226
April 10, 2019

Texas Animal Health Commission

Number Affected: 1;
Age: 14; Gender: Mare; Breed: Quarter Horse (QH); Onset of Clinical Signs: 4/5/2019;
Clinical Signs: Neurologic signs- Moderate; Confirmation Date: 4/9/2019; Horse Status: Affected And Alive; Vaccination Status: Not Reported;
Notes: The positive horse attended a reining event in Ardmore, Oklahoma the week of March 18, 2019. TAHC staff has been in contact with the Oklahoma State Veterinarian to ensure event participants were notified and enhanced biosecurity measures are taken. Since the Oklahoma event, the horse has not traveled to any other event and is under the care of a Brazos County veterinary hospital. The horse was quarantined after showing signs of ataxia and other neurologic signs consistent with EHM. While the risk of exposure to the virus was likely low at the event, owners of horses potentially exposed are encouraged to take precautions. Owners should work with their veterinary practitioners to establish appropriate monitoring and diagnostic plans for any potentially exposed horse(s).;
