Impact on children
Of the approximately 120 million children born in the developing world each year, half will live in households without access to improved sanitation facilities and one fifth into households without access to improved drinking-water sources, at grave risk to their survival and development.
Unsafe drinking water, inadequate availability of water for hygiene and lack of access to sanitation together contribute to about 88 per cent of deaths from diarrhoeal diseases.
Other related diseases
Water, sanitation and hygiene are associated with other diseases, such as pneumonia, trachoma, and worm-related illnesses.
The gender gap
Women and girls bear more of the consequences of poor water, sanitation and hygiene.
Water and sanitation in schools
Unsafe water and unhygienic conditions also have an impact on the health, attendance and learning capacities of school-age children.
Water, sanitation and hygiene activities are vital to children affected by natural disasters, conflict and instability.
