At this time, the Large Animal Hospital at the Lloyd Veterinary Medical Center has not seen or heard of any cases of equine herpesvirus myeloencephalopathy (EHM) in this area. Recently, there have been reports of EHM affecting an unconfirmed number of horses in the United States and Canada. This outbreak appears related to initial cases at a cutting horse show in Ogden, Utah, which was held from April 29 - May 8. Horses at that event may have been exposed to this virus and subsequently spread the infection to other horses. While the true extent of this disease outbreak is uncertain, there is clearly a very significant elevated risk of EHM cases at this time. At this time control of the outbreak is critically dependent on biosecurity. EHM can be a serious disease of horses that can cause abortion and death. Clinical signs include high fever, neurological symptoms and nasal discharge. The virus can spread through the air, contaminated equipment, clothing and hands. Please take appropriate precautions.
