Another Kentucky horse has tested positive for West Nile virus (WNV), E.S. Rusty Ford, equine operations consultant for the Kentucky State Veterinarian’s Office, said in an Oct. 5 statement. There are now nine confirmed cases of WNV in Kentucky horses this year.

The 6-year-old Standardbred mare from Todd County presented on Sept. 26 with ataxia (incoordination) and hyperexcitability. Ford said the mare’s condition worsened and she ultimately became recumbent (unable to rise). She was euthanized on Sept. 29.

Ford said the mare had no WNV vaccination history
