Equine Herpes Viruses
The Thoroughbred Center, KY
Outbreak Update
Source: Kentucky Office of the State Veterinarian
The Office of the Kentucky State Veterinarian has reported that Barn 3 at The Thoroughbred Center in Lexington, KY has been released from quarantine after results of testing on samples collected from each horse were reported negative. In addition to the testing that has been completed, the horses have been monitored daily and our findings support that it has been greater than 14 days since any horse in the barn was last exposed to a clinical case. Meeting the criteria above has qualified the group and the horses in barn 3 to be released from quarantine and restrictions imposed by the KY Department of Agriculture. Barn 30 remains under quarantine. Officials are continuing daily monitoring. There have been no fevers or other symptoms in the group, and the horses in Barn 30 are scheduled to be sampled (swabs and whole blood) and tested by PCR later this week.
