                      World Closes In on Eradicating Polio

   by Carol Pearson

   Never before have so few children in the world had polio. Yet, as World
   Polio Day is observed Saturday, those who are trying to wipe out the
   virus say it's time to step up polio vaccination campaigns. If that
   happens,VOA's Carol Pearson reports, polio could be eradicated by 2019.
