The National Reining Breeders Classic horse show in Tulsa, Okla., saw a positive case of equine herpesvirus late last week, according to Quarter Horse News and the Equine Disease Communication Center.
On April 17, a Quarter Horse was removed from show stabling and transferred to a nearby hospital due to progressing neurological symptoms. The horse, who was vaccinated for equine herpesvirus, was later euthanized. Oklahoma state officials got test results back on the impacted horse on the afternoon of April 20 and identified 14 horses that had direct exposure to the index case. Those horses were quarantined and isolated the same day, and will be released after at least 14 days and two negative tests that come at least a week apart.
The horses that shared the barn with the index horse received two doses of “an amniotic product to reduce viral shedding” and will have their temperatures monitored while they are quarantined.

State animal health officials told Quarter Horse News the show had attracted horses from 22 different states, and as of Friday, they were in the process of contacting those states to determine whether those horses could go home under quarantine.
The show concluded on April 23.
