Etymology

The word "polio" is a shortened form of "poliomyelitis," derived from Greek roots:

  • "polio" (πολιός) means "gray," referring to the gray matter of the spinal cord.
  • "myel" (μυελός) means "marrow," indicating the spinal cord's involvement.
    The term reflects the disease's impact on the nervous system, specifically the gray matter of the spinal cord, leading to muscle weakness or paralysis. Over time, "polio" became the common shorthand for the condition.
