Diarrhoea is the third biggest killer of children under five years old in Sub-Saharan Africa.
(Child Health Epidemiology Reference Group (CHERG) 2012)
Around 315,000 children under-five die every day from diarrhoeal diseases caused by dirty water and poor sanitation. That's 900 children per day, or one child every two minutes.
