By now many of you have seen the circulating posts on social media about the EHV-1 outbreaks down south and although we currently donβt know how many active cases there are, more information is expected to continue to come out over the next week. Itβs important to take extra precaution as the next few weeks unfold.

Equine Herpesvirus is the bug that causes Rhinopneumonitis, a respiratory disease, and depending on the βtypeβ can cause abortion in broodmares and equine herpervirus myelencephalopathy (EHM) - which is a deadly neurologic form of the disease. Outbreaks can spread quickly, especially at shows, barns and boarding facilities, so prevention is key.

Practice strong biosecurity:
-Donβt share water buckets, hoses, grooming tools, or tack
-Wash hands between handling different horses.
-Disinfect stalls, trailers, and equipment regularly.

-Avoid unnecessary horse to horse contact, especially with unfamiliar horses.
-Be cautious at shows, clinics, and events. Keep distance when possible.

-Check temperatures once or twice daily when traveling or when thereβs a known outbreak (Normal temp is 99-101.5)
-Watch for any coughing, nasal discharge, fever, inappetence or lethargy

-Isolate new arrivals for 2-3 weeks
-Use separate equipment and wash hands after handling horses
-Tend to the new or returning horses last

-While vaccines donβt prevent the neurologic form, they help reduce respiratory spread and overall viral load.
-Itβs recommended that horses are vaccinated EVERY 6 MONTHS for flu/rhino (influenza/EHV 1 & 4) due to immunity being short lived.

-Even a horse with mild symptoms can transmit the virus
-Contact your vet if you notice a fever or neurologic signs.
