The risks of medical complacency towards poliomyelitis

What is poliomyelitis? Poliovirus is an enterovirus and exists as three serotypes: WPV types 1, 2 and 3. Spread via the faecal–oral route, poliomyelitis results in subclinical or selflimited infection in most patients, but causes acute flaccid paralysis (AFP) due to anterior horn cell damage in about one in 200 cases.3 Ubiquitous distribution of polioviruses and epidemics of paralysis caused widespread panic throughout the world in the early 20th century.
