Rotary clubs around the world have been working for years to eradicate polio, once a global scourge causing paralysis, respiratory difficulties, even death.
But, younger people might ask, what exactly is polio? Not an unheard-of question for people who did not grow up in a world in which polio often hit communities just as measles, chicken pox, and other diseases did before immunizations sharply reduced their frequency.

Over the years, we have been able to shrink its spread to the point at which, except for occasional isolated cases, it occurs in only two nations — Pakistan and Afghanistan.
