The Vermont Department of Agriculture, Food and Markets has confirmed a case of neurologic equine herpesvirus (also known as equine herpesvirus myeloencephalopathy or EHM) in Grand Isle County.
A horse in Alburgh, Vermont, exhibiting neurologic abnormalities tested positive for equine herpesvirus type 1 (EHV-1). The horse in question is currently under quarantine while the Agency monitors and manages the case with the attending veterinarian.
EHV-1 was recently identified as the cause of equine illness outbreaks in Florida and Europe and has led to the cancellation of several international equine events. No link between the recent Vermont case and these outbreaks has been discovered.
