Kentucky Reports First Equine WNV Case of 2018

An unvaccinated gelding in Kentucky is recovering from the state's first case of West Nile virus (WNV).

Diagnostic testing completed and reported August 28, 2018, confirmed the first equine West Nile virus (WNV) case diagnosed in Kentucky this calendar year. The diagnosis is based on detectable WNV specific IgM antibody and compatible clinical symptoms.

The case was confirmed in a 9-year-old Quarter Horse gelding in Pendleton County. The horse is in stable condition with a favorable prognosis.

Onset of clinical signs occurred on August 23 when the gelding presented with lower lip paresis and muscle fasciculation. During the following 48 hours, the patient showed a progressive rear ataxia and became unable to rise.

The gelding remains hospitalized under treatment and continues to improve. Earlier the evening of August 28, the gelding was found to be bright, alert, responsive (BAR), able to rise with assistance, stand, and was eating and drinking well.

The gelding had not been vaccinated.
