Poliomyelitis
Background
Poliomyelitis: Polio: Infantile Paralysis
Poliomyelitis is caused by an infection with the Poliomyelitis virus, which is an enterovirus. Polio can appear at any age, but used to be more common in young children hence the name Infantile Paralysis. It occurred in widespread epidemics particularly after the Second World War, but these have largely disappeared with the advent on effective immunization in the late 1950's. Occasional new cases do, however appear even in developed countries.
