Kentucky EHV-1 Investigations - Updated 1/26/17

KEENELAND – Rice Road Training Center Testing of samples collected on 1/25/17 from horses in both barns has been completed and reported. The testing did identify a second positive horse in the first barn, bringing the total EHV1 ‘wild strain’ positive horses in that barn to two (2). That horse, a 3yo TB colt was positive on nasal swab, negative on blood. The colt was moved from the barn to the secured isolation last night (Wed 1/25). Testing of horses in the second barn did identify three (3) horses, all are 2yo TB fillies, to be EHV1 ‘wild strain’ positive by PCR on the nasal swabs, testing of whole blood samples from each horse were reported negative for EHV1. These additional positive horses were moved from the barn to the secured isolation earlier tonight. Each of the two quarantined barns are secured, entry into the barns is restricted and biosecurity levels are implemented at highest level. In addition to the affected barns, heightened biosecurity has been implemented in the entire barn area that includes restricting entrance into each barn, and requires disinfecting upon entry and exit of each barn. Designated times have been established for the horses from the quarantined barns to gain access to the track for exercise after the normal training hours have elapsed and the general population of horses have returned to their barns. TURFWAY PARK The two positive horses identified and described on 1/24/17 were moved offsite and are isolated on a private farm. Monitoring of the general population continues with no evidence of further cases developing. The previously established and described protocols for ship-ins, racing, training and monitoring remain in effect. Oldham Premises I Testing of the barn’s population of horses that had been exposed to EHV1 was completed yesterday (1/25/2017) with each horse testing NEG on both nasal swabs and whole blood. Having been greater than 14 days post exposure, and each horse now having two (2) negative sets of results – The Ky Office of State Veterinarian has released the quarantine imposed on January 5, 2017 and the horses are under no further restrictions. Oldham Premises II Daily monitoring and assessment of the horses in the exposed quarantine barn continues with no evidence of further transmission of EHV1.
