Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring at about a 25–40% rate (latest data greater than 80%). They 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.
A small percentage, about one in 200, of individuals who contract the polio virus suffer paralysis. A few could contract meningitis if the polio virus attacks the covering of the spinal cord or brain.
Up to 0.5% develop paralysis of or weakness in the arms and/or legs—and up to 10% of those paralyzed die. Even people with mild infections can experience post-polio syndrome (PPS) decades later.
Polio-like syndrome is a general description of a group of symptoms which mimic polio, including rarely permanent paralysis. Various triggers have been found, including some viruses from the same virus group as polio: enterovirus 68, enterovirus 71, and coxsackievirus A7. [1] [2] These are suspected in many cases of acute flaccid myelitis.
