Kentucky Has Fourth WNV Case

This case was originally confirmed on Oct. 29, 2014, as a 10-year-old gelding being affected with West Nile virus. The diagnosis is based on detectable WNv IgM and compatible clinical symptoms. The Quarter Horse gelding was in Allen County with no history of vaccination.

The onset of clinical signs was Oct. 26, when the horse was showing mild rear limb ataxia and was febrile (with a temperature of 101.5 degrees Fahrenheit). The horse is reported to be much improved.
