An update for our equine owners as this outbreak has developed - with an EHV-1 positive case in the area, we are recommending barns take the below extra precautions when able. We're also sharing one of AAEP's original posts for even more detailed resources.
1. Quarantine for 30 days - no one in or out.
2. Flu/Rhino booster every 3 months for horses that have not been directly exposed. The vaccine is for the respiratory strain, but may offer cross protection. There is currently no vaccine available for the neurologic form of equine herpes virus. Call us for boosters!
3. Signs to monitor for: Any neurologic or respiratory clinical signs, including generalized or hind-end weakness, or runny nose. If you notice these signs, please let us know right away and begin regular temperature checks.
4. Although traveling between barns is not recommended, if you do, please disinfect tact and boots, change clothes, and wash hands between barns.
5. If your barn becomes exposed with a known positive case - please reach out to us immediately for more updated & customized guidelines.
If you have any concerns, don't hesitate to message here or call!
As we continue to monitor the current outbreak of the neurologic form of equine herpesvirus (EHM) infection, let's take this opportunity to discuss once more the importance of biosecurity measures to stop disease spread. We recommend the following biosecurity precautions for horse owners, particularly if their horses have recently traveled to horse shows or were exposed to horses that have traveled:
1) Monitor horses for clinical signs (including fever, discharge from the nostrils, toe-dragging or a lack of balance) and take the temperature twice daily. Temperature greater than 101.5 F is considered a fever.
2) Immediately isolate any horse(s) showing clinical signs. Equine herpesvirus is an aerosolized virus and is spread through shared airspace, direct contact, and contaminated caretakers or equipment. A good isolation area is a separate barn or shelter that does not share airspace with healthy horses.
3) Implement movement restrictions until the situation is evaluated.
4) Contact your veterinarian to evaluate your horse and to propose a comprehensive biosecurity protocol.
5) Increase biosecurity measures that include extensive cleaning and disinfection of surfaces and equipment that come in contact with affected horses: wash or sanitize your hands between interacting with horses; take time while filling water buckets and feed tubs, do not cross contaminate; minimize the use of shared equipment and tack.
6) Make sure your horse is up to date on vaccinations.
7) Establish communication with all parties involved (owners, boarders, trainers, etc.).
