Neurologic Diseases in Georgia and Ontario Horses

A Georgia horse was confirmed with West Nile virus and an Ontario, Canada, horse was euthanized for EEE.

Georgia’s Seventh Equine WNV Case

The Georgia Department of Agriculture has confirmed a case of West Nile virus (WNV) in Gordon County. The affected horse was a 6-year-old Tennessee Walking Horse of unknown vaccination status. 

The 2017 total reported WNV cases in Georgia to date are six confirmed and one presumptive positive.

Ontario EEE Horse Euthanized

On October 12, 2017, the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) was notified of a confirmed case of Eastern equine encephalitis (EEE) in a horse in Bruce County. The 12-year-old, unvaccinated mare with no travel history had a sudden onset and progression of neurologic signs. The horse was found down in the field, became unresponsive and was euthanized. A post-mortem examination was performed at the Animal Health Laboratory in Guelph, Ontario, and EEE was confirmed by testing of brain tissue.

The Equine Disease Communication Center (EDCC) works to protect horses and the horse industry from the threat of infectious diseases in North America. The communication system is designed to seek and report real time information about disease outbreaks similar to how the Centers for Disease Control and Prevention (CDC) alerts the human population about diseases in people.
