In pictures: Sierra Leone slum

Below sea level, the slum sits at the point where two of the city’s main rivers reach the Atlantic Ocean.

During the heavy rains of June to August, the water – which has a bluish tinge from all the effluent – regularly rises up and floods homes.

A Save the Children survey found all the children had respiratory problems such as coughs and colds, while there were also incidences of malaria, leprosy, chicken pox and grave diarrhoeal illnesses.
