Polio

Polio, short for poliomyelitis, is an infection that can affect nerve cells in the spinal cord. While most infections do not result in illness, severe infections can kill nerve cells. This leaves muscles permanently weak or damaged. About 1 in every 100 persons infected with the virus becomes paralyzed.

Paralytic disease still exists in certain parts of Africa, Southeast Asia and India. Until the virus has been eliminated worldwide, the risk to Canadians remains high and immunization in childhood is recommended.
