ABSTRACTDiarrheal diseases among children are still the problems of concern globally despite of much progress in primary health care, hygiene-sanitation and living condition. According to WHO estimation, in 1997 there were 4 billions episodes of diarrhea in the world that contributed up to nearly 2.5 millions deaths. The diarrheas were the leadingcauses of morbidity and the sixth causes of mortality of human in the world. In recent decades, with the discovery and utilization of Oral rehydration solution (ORS) as well as other Oral rehydration therapies (0RTs) and the promotion of appropriate feeding and caring practice at the community levels, the mortality due to diarrhea is reduced. However, diarrhea is still contributing up to 19% to child mortality in the developing world.Results from 276 surveys conducted in sixty countries between 1981 and 1986 indicated that children under five in developing countries suffered 3.5 diarrheal episodes each year. Incidence of diarrhea is higher in certain communities especially the rural poor. High diarrheal prevalence and mortality among young children lead to serious consequences in health and socio-economy fiom household to the world levels.
