There is no cure for polio, it can only be prevented by a vaccine administered in divided doses during childhood.

Global campaigns have reduced polio cases by 99 percent. In 1988, the disease paralyzed or killed nearly 350,000 people in the world. In 2010, fewer than 1,500 cases detected. However, the disease still exists in Pakistan, Afghanistan, India and Nigeria. Polio could be the second disease eradicated from our planet after smallpox.
