Encephalitis or encephalomyelitis? Which is correct? Both, but there is a difference. Encephalitis is inflammation of the brain. Encephalomyelitis is inflammation of the brain and spinal cord.

The most familiar equine encephalomyelitis viruses are Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE) and Venezuelan equine encephalomyelitis (VEE). Among others, rabies and West Nile viruses often lead to encephalitis.
