    Unclean water and poor sanitation are the leading causes of child mortality. Childhood diarrhea is closely associated with insufficient water supply, inadequate sanitation, water contaminated with communicable disease agents, and poor hygiene practices. Diarrhea is estimated to cause 1.5 million child deaths per year, mostly among children under five living in developing countries.
