Reaching every child: the polio programme leaves its legacy

Four-year-old Pooja lives with her family in a jhuggi – a makeshift shanty made of corrugated iron – on a construction site on the outskirts of Kolkata, where her father has been working for the past few months.
The settlement is crowded with temporary workers and their families living in sheds and slum dwellings in and around the buildings that are under construction. They don’t have access to toilets or safe drinking water.
Pooja’s father’s work is precarious. Once the construction at this site is completed, he and his family will pack up their few possessions and move on, setting up home wherever he can find work.
