New Delhi, March 28 (ANI): The World Health Organisation declared India free of the crippling polio virus during a ceremony in New Delhi, making the country's almost two-decade-long, multi-billion-dollar effort one of the biggest public health achievements in recent times. India's last case of the wild polio virus was detected in January 2011 in a two-year-old girl in West Bengal. The ceremony was organised in New Delhi to give the official certificate to India for this achievement of eradicating the disease from the country. Southeast Asia director of WHO, Poonam Khetrapal Singh, said that the ceremony marks one of the biggest public health achievements in the world.
