Not just this, Indians have another reason to smile as the World Health Organisation (WHO) is all set to officially certify India as a polio-free nation after the last of random samples picked up would be tested.

For the record, India reported its last case of polio on January 13 last year, from Kolkata in West Bengal.

Further, there has been a constant drop recorded in polio endemic states like Uttar Pradesh and Bihar with zero case recorded in the year 2011 in both the states.

Union Health Minister Ghulam Nabi Azad said on January 6, "For the last two years we have been a polio free country. If by January 13, there are no polio cases in the country, then we will be declared polio free".
