The South Dakota State Veterinarian has confirmed a case of equine herpesvirus myeloencephalopathy in a 19 year old QH mare with neurologic illness. The horse belongs to a college rodeo participant and has extensive recent travel history to rodeos within the Great Plains Region. The horse has been isolated and voluntarily quarantined in Brookings, SD, upon returning from an event in Hastings, NE, the weekend of April 27-28, 2018. Owners of horses known to be directly exposed to the index horse are advised to restrict movement and monitor their horses for signs of illness, including twice daily temperature monitoring.
