Venezuelan Equine Encephalomyelitis

Venezuelan equine encephalomyelitis (VEE) is a mosquito-borne viral disease, affecting all equine related species, such as horses, mules, donkeys, and zebras. Humans can also contract this disease. In horses, the disease typically starts as a mild fever that progresses into severe and often fatal encephalomyelitis (inflammation of the brain and spinal cord). In some cases it can produce an acute disease causing sudden death. In humans, the virus usually causes flu-like symptoms such as fever and headaches.

In Canada, VEE is a reportable disease under the Health of Animals Act, and all cases must be reported to the Canadian Food Inspection Agency (CFIA).
