There are currently confirmed and suspected cases of EHV-1 (including neurologic EHM cases) in our region. For now, we recommend treating this as a serious but manageable outbreak and tightening biosecurity at home.
What to Do Right Now
1. Stop hauling unless absolutely necessary
Pause shows, clinics, lessons, and non-essential hauling for the next few weeks. Horse movement is the main way EHV-1 spreads.
2. Take temperatures twice daily
• Normal: ~99–101.5°F
• If your horse is 101.5°F or higher, call your veterinarian.
Fever often appears before nasal discharge or neurologic signs.
3. Call your vet immediately if you see:
• Fever
• Weakness, incoordination, or “drunken” gait
• Standing with hind legs wide apart
• Tail tone changes or difficulty urinating
• Lethargy or decreased appetite
Early evaluation and supportive care can improve outcomes.
4. Tighten biosecurity at home
• Do not share water buckets, hoses, grooming tools, tack, or stalls.
• Disinfect trailers, thermometers, gates, and crossties regularly.
• Immediately isolate any horse with a fever or suspicious signs.
5. Vaccination: what it does (and doesn’t) do
• EHV-1 vaccines do not prevent neurologic EHM or stop a horse that’s already incubating the virus from getting sick.
• However, they can reduce viral shedding and viremia, which helps slow barn-wide and community spread.
• Boosters are generally most useful if it’s been >90 days since the last EHV-1 vaccine or your horse is entering higher-risk environments.
• Do not vaccinate a febrile or clearly exposed horse without talking to your veterinarian first.
6. Key FAQs for owners
• Is this contagious to people? No.
• Can a horse carry/spread EHV-1 without a fever or nasal discharge? Yes, that’s possible.
• How long can the virus survive in the environment? Up to ~2 days on dry surfaces and up to ~2 weeks on wet/dirty surfaces if not properly disinfected.
• Best disinfectants? Use products labeled for viruses such as accelerated hydrogen peroxide, phenolic disinfectants, or quaternary ammonium products. Avoid relying on diluted household bleach alone.
