Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring in more than 80% of polio infections. The symptoms are caused by the damaging effects of the viral infection on the nervous system and typically occur 15 to 30 years after an initial acute paralytic attack.
Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
Most infections are asymptomatic; a small number cause a minor illness that is indistinguishable from many other viral illnesses; less than 1% result in acute flaccid paralysis. This article lists people who had the paralytic form of polio. The extent of paralysis varies from part of a limb to quadriplegia and respiratory failure.
The virus infects the throat and intestines, and can cause flu-like symptoms. Paralysis from the polio virus is rare. This year, polio cases have been detected in New York state, London and Jerusalem.
For example, Lovett mistakenly believed that Landry's ascending paralysis (GBS), was one of the clinical presentations of paralytic polio. [ 7 ] : 455 In 1921, an American physician would assume that if an individual developed a sudden, non-traumatic flaccid paralysis, it was due to paralytic polio.
The U.N. agency estimates that 1 in 200 polio cases results in permanent paralysis, usually of the legs. Among children who are paralyzed, up to 10% die when their breathing muscles are paralyzed.
The "Megalopolis" director contracted polio around the age of 9 and was left bedridden and paralyzed for a portion of his childhood."I remember that night. I was feverish and they took me to a ...
Rows of iron lungs filled hospital wards at the height of the polio outbreaks of the 1940s and 1950s, helping children, and some adults, with bulbar polio and bulbospinal polio. A polio patient with a paralyzed diaphragm would typically spend two weeks inside an iron lung while recovering. [36] [37]
