There have been lots of posts going around talking about Neurogenic EHV-1/EHM in Montana.
🚨 As of last night, the Montana State Veterinarian issued a notice stating that there are NO KNOWN CLINICAL HORSES OR CONFIRMED CASES IN MONTANA 🚨
However, in order to minimize the risk of infecting horses in Montana the Department of Livestock is issuing an emergency rule that all horses entering Montana are required to have their CVI (Health Certificate) issued within 72 hours of entering. This also means that they have disabled all EECVI (6 month extended Health Certificates) for horses entering Montana.
There are a number of horses who attended affected events and have entered Montana, but the state is reaching out directly to those owners to watch for clinical signs. Again, no cases have been confirmed in Montana.
‼️ What you can do:
•Keep your horses at home and don’t travel unless you absolutely need to.
• If you are traveling with your horse, we recommend vaccinating them at least 2 weeks prior to travel. The EHV vaccine will not prevent your horse from contracting EHM but it may reduce severity of the disease.
•If your horses don’t travel, but you yourself travel to other barns or equine facilities your horses are still at risk and it would be a good idea to vaccinate them.
•The Fluvac Innovator EHV 4/1 is what we give most of our client’s horses and it has a 6 month efficacy. So even if you vaccinated in Spring, it’s time to booster it this Fall/Winter.
• If we vaccinate your horses (as opposed to store bought vaccines), the vaccine company stands behind the efficacy when administered by a vet. This means if your horse does end up with a fever, you could get reimbursed for treatment.
Just be mindful of the exposure your horses have and take the necessary precautions to protect them.
