E.S. “Rusty” Ford, equine operations consultant for the Kentucky Office of the State Veterinarian, released the following update on an EHV-1 outbreak in Woodford County, Ky., on Monday. The outbreak was first announced March 11 after one horse at a training center was hospitalized with neurologic symptoms. On March 12, five more horse horses tested positive.
The additional 24 horses in Barn B of the index EHV-1 affected premises were sampled on Friday due to potential exposure of indirect transmission (riders) having occurred prior to confirmation of the index case. Two horses from this group had a trace amount of EHV-1 DNA detected in the nasal swab and were removed from the barn and segregated on Saturday.
To date, 18 horses in index Barn A and 22 horses in Barn B have had one set of negative test (nasal swab and/or blood) . The last febrile horse was removed from Barn A and placed in isolation on March 10, 2021. There have been no clinical horses in Barn B since the start of the outbreak.
Five of the nine horses in the isolation barn have tested positive with the last fever reported on Friday March 12, 2021. All horses in isolation are being monitored by the attending veterinarian.
A second round of testing is being planned for the horses in barns A, B and Isolation.
The management and staff of the premises continue to implement enhanced biosecurity and health monitoring protocols including multiple daily temperature recordings. Additionally, these enhanced measures have been implemented at other sanctioned training facilities in Kentucky.
Staff from the Office of the State Veterinarian continue to closely monitor the situation.
Appropriate biosecurity and other safeguards are fully implemented at Turfway Park.
Updates will continue to be provided as information is learned.
