In-Depth Analysis

Equine Herpesvirus type 1 (EHV-1) is a highly contagious virus that can cause a range of clinical signs in horses, from mild respiratory illness to severe neurological disease (Equine Herpes Myeloencephalopathy or EHM). Outbreaks often occur after horses return from large events where they can easily spread the virus.

EHV-1 can lead to: * Respiratory disease * Abortion in pregnant mares * Neonatal death in foals * Neurological issues (EHM)

**Preventative Measures**

**Temperature Monitoring:** Check rectal temperatures twice daily. A temperature of 101.5°F or higher is a concern.
**Isolation:** Isolate any horse showing signs of fever or illness.

The current outbreak is suspected to be linked to the WPRA World Finals and Elite Barrel Race held in Waco from November 5-9. Horses that attended the event have begun exhibiting symptoms, prompting concerns and increased vigilance among horse owners.

The Uvalde Rodeo Qualifier was cancelled as a result of the outbreak. Additional information regarding how this cancellation will affect the contestant field for the San Antonio Rodeo in February will be provided once details are finalized.
