Equine Herpesvirus-1 is a form of DNA virus that causes a spectrum of symptoms from respiratory to neurological, and can even cause abortion. EHV-1, in its neurological form, can cause Equine Herpesvirus Myoencephalopathy, which attacks the CNS and can be fatal.

The most common route of transmission is direct horse-to-horse contact, via respiratory droplets. Indirect transmission is possible by contaminated clothes, tack, grooming supplies, etc.
By restricting horses' movements onto and off your property, and following good biosecurity practicesโlike washing your hands regularly, avoiding sharing tack and grooming supplies, and limiting contact with horses that aren't under your direct careโyou can reduce the risk of disease transmission.
