What Is EHV-1?
Equine Herpesvirus-1 is a contagious viral disease that affects horses and can cause:
- High fever
- Respiratory symptoms
- Neurological disease (EHM—Equine Herpesvirus Myeloencephalopathy)
- Abortions in pregnant mares
The neurological form of EHV-1 (EHM) is of particular concern because it can spread rapidly in barns and equine event facilities.

Confirmed Outbreak Details
According to TDA and TAHC:
Multiple horses in Texas have tested positive for EHV-1.
Some horses have developed neurological symptoms consistent with EHM.
Quarantine and movement restrictions have been implemented at affected locations.
Epidemiological investigations are ongoing to determine the source and potential spread.
Commissioner Miller emphasized that early reporting, strict quarantine, and enhanced sanitation procedures are critical to containing the virus.

Recommended Actions for Horse Owners
1. Strengthen Biosecurity Measures
Isolate new or returning horses for at least 21 days.
Avoid sharing equipment such as water buckets, halters, or grooming tools.
Disinfect stalls and trailers regularly.
2. Monitor Horses Closely
Watch for signs including:
- Fever over 101.5°F
- Nasal discharge
- Reduced coordination
- Hind-limb weakness
- Lethargy or decreased appetite
Any suspicious symptoms should be evaluated by a licensed veterinarian immediately.
3. Minimize Horse Movement
TDA and TAHC recommend avoiding unnecessary travel to shows, sales, or events until the outbreak is under control.
4. Follow Official Updates
The Texas Animal Health Commission provides real-time updates on quarantines, confirmed cases, and recommended precautions.

How EHV-1 Spreads
The virus spreads through:
- Direct horse-to-horse contact
- Contaminated surfaces (stalls, trailers, equipment)
- Human handlers’ clothing or hands
Because the virus can survive for hours—or even days—on contaminated objects, strict sanitation is crucial.

Protection at Equine Events
Facilities hosting competitions, sales, or training activities are encouraged to:
- Require temperature checks before entry
- Provide additional hand-washing and sanitizing stations
- Space stalls and restrict barn access
- Enforce strict no-sharing-equipment policies
Event organizers are also advised to report any suspected illness immediately.

Why This Matters for Texas
Texas is home to one of the largest equine populations in the United States, supporting:
- Rodeo circuits
- Racing operations
- Breeding farms
- Performance horse industries
An outbreak of EHV-1 poses risks not only to horse health but also to the state’s agricultural economy.

Key Takeaway
The Texas Department of Agriculture and the Texas Animal Health Commission are urging all individuals involved with horses to take immediate steps to prevent further spread of EHV-1.
Early detection, prompt isolation, and strong biosecurity are the most effective tools to protect the equine community.
