Answer:
Polio, short for poliomyelitis, or infantile paralysis, is an infectious disease caused by the poliovirus.[1] In about 0.5 percent of cases there is muscle weakness resulting in an inability to move.[1] This can occur over a few hours to a few days.[1][3] The weakness most often involves the legs but may less commonly involve the muscles of the head, neck and diaphragm.[1] Many people fully recover.[1] In those with muscle weakness about 2 to 5 percent of children and 15 to 30 percent of adults die.[1] Another 25 percent of people have minor symptoms such as fever and a sore throat and up to 5 percent have headache, neck stiffness and pains in the arms and legs.[1][3] These people are usually back to normal within one or two weeks.[1] In up to 70 percent of infections there are no symptoms.[1] Years after recovery post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection.[2]
