UNICEF says diarrheal diseases stemming from inadequate water, sanitation and hygiene kill over 800 children under five-years-old every day. Using proper toilets and hand washing – preferably with soap – prevents the transfer of bacteria, viruses and parasites found in human feces which otherwise contaminate water resources, soil and food. This contamination is a major cause of diarrhea, the second biggest killer of children worldwide, and leads to other major diseases such as cholera, schistosomiasis, and trachoma.
