Confirmed Case of Equine Herpes Myeloencephalopathy in Southern Ontario The Ontario Ministry of Agriculture Food and Rural Affairs (OMAFRA) has been notified of a confirmed case of Equine Herpes Myeloencephalopathy (EHM), caused by equine herpes virus 1 (EHV-1), in Southern Ontario. A blood sample from a horse with severe neurological signs tested positive for EHV-1 in early January. The horse was euthanized after its condition deteriorated. On a second farm in the same area, another horse with similar signs was euthanized in late December. No samples were collected from that horse.
