Notice to any horses that have been travelling to events in New Brunswick recently regarding Equine Herpesvirus-1 (EHV-1)
β‘οΈ A positive case of EHV-1 has been confirmed in New Brunswick. It is important for horse owners, trainers, and facilities to remain vigilant and take appropriate biosecurity precautions.
EHV-1 can spread through direct horse-to-horse contact, respiratory secretions, and contaminated equipment, clothing, hands, and surfaces. Some strains can cause respiratory disease, abortion, neonatal death, and the neurological form of the disease (EHM).
π‘οΈ What can you do to help protect your horse?
π΄ Monitor temperatures daily β A fever may be one of the earliest signs of infection.
π« Avoid unnecessary horse-to-horse contact and limit travel when outbreaks are occurring nearby.
πͺ£ Do not share equipment such as water buckets, feed tubs, tack, grooming supplies, or thermometers.
π§Ό Practice good hygiene β Wash hands and disinfect boots, equipment, and frequently touched surfaces.
π₯ Isolate new, returning, or sick horses and follow appropriate quarantine protocols.
π Watch for clinical signs including fever, nasal discharge, coughing, lethargy, incoordination, hind-end weakness, or difficulty urinating.
π There is not a specific vaccination for the neurologic strain of EHV1. That being said, since viremia is a prerequisite for neurologic disease, lowering viral load and shedding through vaccination may theoretically help reduce overall outbreak risks or severity, but it does not directly prevent EHM.
π Contact your veterinarian immediately if you have concerns or notice signs of illness.
Biosecurity is a team effort, and early recognition and isolation are essential in helping reduce the spread of infectious disease.
Stay informed, stay vigilant, and help protect our equine community. β€οΈπ΄
Please follow guidance from your veterinarian and local animal health authorities regarding current outbreaks and movement restrictions.
