We’ve been receiving questions about Equine Herpesvirus (EHV-1) and the neurologic form, EHM, so here’s an update for our Rhythm community. 💙🐴
🔍 What’s happening?
There is an EHM outbreak linked to an event in Texas, with a few secondary cases in nearby states. One isolated case was also reported in Red Deer County, AB.
👉 As of Nov 20, 2025, no cases have been reported in Saskatchewan.
🦠 What is EHV-1?
EHV-1 is a common herpesvirus in horses worldwide. Many infections look like a mild cold, but it can occasionally cause abortion or, rarely, neurologic disease (EHM). Most horses are exposed when young and carry the virus quietly for life.
💉 Vaccines
• Yes — vaccines exist for EHV-1/4.
• No — they cannot fully prevent the neurologic form.
• But — they can reduce respiratory disease and viral shedding, helping limit spread.
Our recommendations:
• At-risk horses (travelling, showing, boarding barns): every 6 months
• Home-based horses with low exposure: annually
• Vaccination can be done any time of year
• Owners may self-administer after purchasing through the clinic
Not sure if your horse needs a booster? Reach out — we’re happy to guide you based on lifestyle and travel.
🏡 Keeping your herd safe
• Don’t share buckets, tubs, tack, or grooming tools
• Take temps for 10–14 days after travel (>38.5°C = fever)
• Separate any horse with fever or nasal discharge
• Limit nose-to-nose contact between unfamiliar horses
• Call early if your horse is off, febrile, or even mildly wobbly
🏥 What we’re doing at Rhythm
• Monitoring official updates daily
• Screening for recent travel when booking
• Enhanced disinfection & isolation for sick horses
