Polio is a serious disease caused by a virus. It attacks the nerves in the spine — the long bundle of nerves down your back — and can leave a person unable to move an arm, a leg, or even the muscles used for breathing. Some people get only a mild fever and get well; some cannot move those muscles for the rest of their lives; in the worst cases, people die.
