ANIMAL HEALTH ALERT:
The Kansas Department of Agriculture’s Division of Animal Health has been closely following the confirmed cases of Equine Herpesvirus Myeloencephalopathy (EHM) positive horses in Texas and Oklahoma following the Women’s Professional Rodeo Association World Finals in Waco, Texas, and the Barrel Futurities of America World Championship in Guthrie, Oklahoma.
KDA has been in communication with all known Kansas horse owners who attended either event in Waco and Guthrie to advise them to isolate those horses for 14 days and to provide them with guidance about how to monitor the health of those horses. The incubation period can last up to two weeks, meaning a horse can appear normal while still shedding the virus and act as a carrier. At this time there are no reported cases in Kansas.
If horse owners intend to travel out of Kansas with their horses, they should contact the state veterinarian office for the state they are traveling to in order to get the current entry requirements.
EHM is a neurologic disease that can spread through horse to horse through contact with nasal discharge or inhalation of airborne droplets. Horses can be exposed through contaminated surfaces such as stalls, water, feed, tack, and transport vehicles. Humans can spread the virus from horse to horse through contaminated hands, clothing, and equipment.
Horse owners should watch for:
• Fever over 101.5
• Nasal discharge
• Lethargy
• Hind end weakness
• Any neurological issues
If you notice any of the symptoms, please contact your veterinarian immediately. Cases that show neurological issues are considered a medical emergency.
Additionally, the Equine Disease Communication Center has created a page to provide outbreak information. This page will be updated regularly and will provide links to more information. You can find it here: https://equinediseasecc.org/alerts?alertID=4722
For questions about quarantine or EHM exposure, call KDA Division of Animal Health at 785-564-6601.
