This morning (Oct. 10), the Kentucky State Veterinarian's office sent out an alert that the sixth equine case of West Nile virus had been confirmed.
The University of Kentucky's Livestock Disease Diagnostic Center confirmed the diagnosis in a 17-month-old Tennessee Walking Horse based on positive Igm and compatible clinical signs. The horse had no history of vaccination, and he was still alive at the time of this report.
The colt began showing signs of moderate ataxia and hyperexcitability on Oct. 5, then was reported to be improving on Oct. 9.
