The North Dakota State Board of Animal Health and the North Dakota Department of Agriculture’s Animal Health Division are reminding owners to take steps to protect their horses from equine herpesvirus-1 (EHV-1). They announced last week that a horse from McKenzie County has been diagnosed with equine herpesvirus myeloencephalopathy (EHM), the neurologic manifestation of the virus.
