Myth Busting

Myth: Only horses showing clinical signs can spread equine herpes virus infection

Horses can transmit the virus without showing any clinical signs. Usually, the respiratory disease caused by EHV causes symptoms in young horses – weanlings and yearlings.1

Myth: Once recovered, a horse is no longer infectious

This is not true – a horse can transmit the equine herpes virus even after they have recovered.1

Myth: Once infected, a horse cannot have a recurrence of symptoms

Once infected, a horse can have a relapse of symptoms, caused by a reactivation of the virus. This may occur on and off throughout the horse’s lifetime.1
