Update 1/13/20: As of January 10, the group of 150 horses is still under quarantine. Eight EHM cases have been identified (2 laboratory confirmed and 6 presumptive). Of these, 2 horses died, 3 were euthanized, and 3 horses are recovering with mild neurologic signs of hindlimb ataxia and/or urine dribbling. There have also been 4 abortions reported during this time period including one of the EHM horses that died. None of the mares or foals on the property are vaccinated. Prior to the outbreak, on October 29, the North Dakota Board of Animal Health was notified by Brand Inspection of a shipment of bucking horses that had been moved interstate into North Dakota without a health certificate, Coggin’s testing or brand certificate. The group of mares currently exhibiting neurologic signs are maintained on pasture 1/4 mile away from the location in Bottineau County where the illegally imported horses had been held.
