oa SA Pharmaceutical Journal - Polio : aiming for global eradication : review



Poliomyelitis, derived from the Greek words polio (grey) and myelon (marrow, indicating the spinal cord), is a viral infection that can cause paralysis when the spinal cord is affected. The successes achieved in the past to control and eradicate polio in several parts of the world, raises the hope of total world eradication of polio. Smallpox is the only virus to date that has been completely eradicated world-wide. Even though several factors pertaining to the polio virus and adverse effects with vaccination against polio may render the process of polio eradication more complex than that of smallpox, successful eradication of polio in several countries globally, is an indication that world-wide eradication of polio is well within reach.
