Diarrhea, pneumonia, and birth complications are the top three killers of children under age 5 worldwide. Diarrhea is also a leading cause of undernutrition in this age group, and one-third to one-half of all child mortality cases are linked to undernutrition. If mothers and other caregivers used basic hygiene practices and had better access to safe water and adequate sanitation this could greatly reduce under-5 deaths and improve child nutrition.
