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 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.
Aug. 13—As improbable as it initially sounded last month, polio just might be making a resurgence across the U.S. and the world. To understand what that means emotionally, as well as clinically ...
In its early stages, poliomyelitis — known as polio — causes fatigue, headaches, ... and around 5% to 10% of paralyzed patients die when their breathing muscles become immobilized. The disease ...
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.
There is also a condition called "post-polio syndrome" in which children who seem to fully recover from polio initially can develop neurologic complications, such as muscle weakness or paralysis ...
