Eastern equine encephalitis virus (EEE), also known as sleeping sickness, and Western Equine Encephalitis (WEE) are viral diseases that cause inflammation of the brain and spinal cord. Wild birds are a natural reservoir for EEE and WEE viruses, and mosquitoes that feed on these birds can transmit the virus to mammals, including horses and humans.

Does your horse have trouble responding to the bit? Does he hold his head awkwardly at times, or seem to have problems chewing? Does he show unexplained behaviour under saddle or have problems with certain gaits or leads? Or does he toss his head a lot, especially when pressure is applied with his bit or perhaps a hackamore?

Movement of horses is helping to spread the disease - Strangles is one of the most commonly diagnosed infectious diseases of horses. Infection results in significant health and welfare consequences and economic costs. Most affected horses recover; however, about 10 percent remain as carriers, free of clinical signs but capable of spreading the disease.
