📢 Important Update for Horse Owners: EHM Outbreak Now Confirmed in Eight States, horse count grows to 32.
We’re bringing you the latest because you deserve clear, accurate, and timely information to keep your horse safe. Here’s what we know as of midday 11/25/25:
The neurologic form of EHV-1, known as EHM, has now spread to at least eight states, with dozens of confirmed cases.
Latest counts:
Texas: 14 horses with neurologic EHM.
Oklahoma: 5 total (1 non-neurologic EHV-1 + 4 EHM).
Louisiana: 3 EHM cases.
New Mexico: 3 EHM.
South Dakota: 1 EHM.
Colorado: 1 EHM.
Arizona & Washington: EHV-1 positive horses with no neurologic signs so far.
EHM attacks the nervous system. Key warning signs: fever, hind-limb weakness or stumbling, urine dribbling, and in severe cases inability to stand.
Many horses can recover with timely veterinary care — in past outbreaks, survival rates were around 60-70%.
🔍 What you can do today:
Monitor your horses’ temperatures twice daily (fever may be the first clue).
Enforce biosecurity: no nose-to-nose contact with unfamiliar horses, no sharing tack, buckets, grooming tools.
Isolate any horse that shows symptoms, and contact your vet immediately.
Keep updated: we’ll continue reporting daily as new states and cases emerge.
We’re committed to giving everyday equestrians the tools, knowledge, and resources to protect their horses — whether hobby, performance, or working partners. Share this post with your barn-mates, riding club, and social circle to raise awareness and keep our community safe. 🐴💛
