Potomac Horse Fever Case Confirmed In Tennessee

The State Veterinarian is advising all horse owners to be alert as Potomac horse fever has been confirmed in a horse in Davidson County, Tn.
Freshwater snails are the source of the bacteria that causes Potomac horse fever. Horses may be exposed when drinking from creeks or rivers, and can then suffer from colic, fever, and diarrhea. Potomac horse fever has not been found to directly transmit from horse to horse.

Another potentially deadly disease, strangles, was confirmed in four horses at a private facility in Shelby County last month. This disease is a contagious upper respiratory tract infection that causes lymph nodes to swell around the head and neck, possibly leading to coughing, difficulty swallowing, airway obstruction, or death. Other symptoms can include nasal discharge, fever, and depression. According to the veterinarian treating the Shelby County horses, all are improving and are under voluntary quarantine until they fully recover.
Neither strangles nor Potomac horse fever are a threat to human health.
