The world's leading health body is expected to declare that Nepal is free of polio, after no news cases of the disease were found there in three years.

Up until the 1990s, as many as 250 people were disabled by polio every year. However, a campaign involving more than 50,000 volunteers went door to door in villages across the country, ensuring every child was vaccinated against the disease.
