Polio quietly preyed on thousands of young Canadians. The disease caused paralysis, deformed limbs and in the most severe cases, death by asphyxiation. In Canada, polio was so feared that as recently as the 1950s, it closed schools, emptied streets and banned children under 16 from entering churches and theatres. In 1955 it looked as though a miraculous polio vaccine signalled an end to new cases of the crippling disease. But a recent medical condition known as post-polio syndrome has survivors reliving the sequel to this once-forgotten nightmare.
