India marks one year polio-free
The US's top health official has administered polio drops to a child in New Delhi as India marked one year since its last case of the crippling disease.
The one-year milestone is a major victory in the global effort to eradicate polio.
If no previously undisclosed cases are uncovered in the coming weeks, India will be removed from the list of endemic countries.
Only Pakistan, Afghanistan and Nigeria would remain on the list.
US Health and Human Services Secretary Kathleen Sebelius marked the day by administering the oral polio vaccine to children at a maternal health clinic in New Delhi.
India's success in fighting polio has been credited to a partnership between the government, the World Health Organisation, Unicef and Rotary International.
