No new polio cases have been reported in India for the past one year. This has been the greatest public health achievement for India with the last polio case detected in West Bengal on Jan 13, 2011. The World Health Organization (WHO) will declare India as polio free only when there is no case of paralytic poliomyelitis by wild polio virus for three consecutive years.
Joint secretary in the Union Health Ministry Anuradha Gupta said, "It's a big milestone - considering that there was a time when India had more than 200 thousand cases every year."
The WHO said, "If all pending samples for the virus test negative, India- once regarded as the world's epicentre for polio- will become free of the disease for the first time in its history, reducing the number of polio-endemic countries to three: Pakistan, Afghanistan and Nigeria."
