Arizona’s state veterinarian confirms Equine Herpesvirus Myeloencephalopathy (EHM) in a yearling. EHM is the neurologic form of EHV-1.

The Maricopa County filly exhibited neurological signs leading to a state-ordered quarantine. Additionally, another yearling on the property traveled to an event 3-weeks prior. It is showing neurologic signs although the horse tested negative for the equine herpesvirus (EHV). The state notified the event organizer in order to offer recommendations to the participants, including biosecurity measures.
