Horse Equine Herpesvirus Welfare

Equine herpesvirus causes respiratory disease, abortion storms, and neurological disease in horses, with outbreaks causing significant welfare harm across equestrian facilities.

Key Facts

EHV-1 and EHV-4 cause respiratory disease and EHV-1 can cause abortion and neurological disease
Neurological EHV causes ataxia, weakness, and bladder dysfunction with poor prognosis
Outbreaks at competition facilities can affect hundreds of horses
Vaccination reduces respiratory disease but does not fully prevent abortion or neurological forms
Strict biosecurity during outbreaks is essential to prevent spread

Welfare Considerations

EHV outbreaks cause acute respiratory suffering and potentially fatal neurological disease in affected horses. Vaccination combined with biosecurity protocols reduces outbreak frequency and severity, making proactive management a welfare responsibility for horse owners and facilities.

What You Can Do

Vaccinate your horse against EHV according to your vet's recommended schedule
Implement biosecurity protocols when new horses arrive at your yard
Isolate and seek veterinary advice immediately if your horse shows EHV symptoms
