🔴 EHV Alert: Recent Outbreak in Texas & Oklahoma
Important Biosecurity & Prevention Guidelines
There have been confirmed EHV-1 and EHV-4 exposures linked to recent events in Texas and Oklahoma, including the WPRA Finals, the 377 Arena (Nov 15–16), and the BFA in Oklahoma.
If your horse attended any of these events, strict quarantine for 14–21 days is strongly recommended.
EHV spreads easily through nasal discharge, aerosol droplets, shared equipment, contaminated stalls/trailers, and even human hands and clothing.
Horses can shed the virus before showing symptoms, making quarantine absolutely essential.
Once infected, horses can become lifelong carriers. Even healthy-looking horses may intermittently shed the virus when stressed — traveling, competing, or changing environments — which explains why outbreaks spread so quickly after large events.
⚠️ What to Watch For
• Fever, nasal discharge, cough, lethargy
• Enlarged lymph nodes
• Late-term abortion or foal loss
• Neurologic signs (EHM): hind-end weakness, stumbling, urine dribbling, difficulty rising
Incubation: 2–10 days
Testing: PCR on nasal swabs and whole blood
Treatment: Supportive care, anti-inflammatories, antivirals for EHM cases
🛑 Quarantine Guidelines for Exposed Horses
• House at least 30 feet away from all other horses
• No nose-to-nose contact
• Separate halters, buckets, pitchforks, grooming tools
• Change clothes or use protective gear before and after handling
• Take temperatures twice daily
• Monitor closely for respiratory or neurologic changes
Disinfection: Clean organic debris → disinfect with a 1:10 bleach solution → let dry completely.
Routine vet appointments should be postponed for 14–21 days. Emergencies can be evaluated in a designated quarantine area.
Vaccination:
• Not recommended for exposed horses
• Horses without any known exposure should receive a booster if not vaccinated in the past 3 months.
