The World Health Organization says that for the first time in history an entire year has passed in which no child in India has been paralyzed by polio. The last case recorded was that of a two-year-old girl in the state of West Bengal on January 13, 2011. WHO calls this achievement particularly significant, as India always has been considered the toughest place on earth to stop the polio virus. Now that India has stopped the transmission of the wild polio virus, only three polio endemic countries remain, Nigeria, Pakistan and Afghanistan. Lisa Schlein for VOA News, Geneva.
