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.
Itzhak Perlman, a polio survivor, plays the violin while seated. Poliomyelitis (often simply called polio) is an acute viral infection that involves the gastrointestinal tract and occasionally the central nervous system. Poliovirus is acquired by faecal–oral or oral transmission.
The distinct speciation of poliovirus probably occurred as a result of a change in cellular receptor specificity from intercellular adhesion molecule-1 (ICAM-1) (used by C-cluster Coxsackie A viruses) to CD155, leading to a change in pathogenicity and allowing the virus to infect nerve tissue. The mutation rate in the virus is relatively high ...
For roughly 80 years, she has coped with the aftermath of a polio infection, including the late effects of polio, called post-polio syndrome. She now needs a wheelchair or mobility scooter to get ...

A few could contract meningitis if the polio virus attacks the covering of the spinal cord or brain. Polio is fatal for 2%-10% of those paralyzed or between 1 in 2,000 to 1 in 10,000 of those ...
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.
