Household water treatment and safe storage

Using theory for research and design of HWTS interventions Beyond childhood mortality, the negative impact of exposure of children to fecal bacteria includes long-term consequences on children’s physical and mental development, as indicated by undernutrition, poor weight-height ratios, stunting and disability adjusted life years (DALYs) (Guerrant et al., 2002). In addition, recent studies on environmental enteropathy show that chronic exposure to fecal contamination negatively affects the intestinal absorptive and immunologic functions that limit the impact of nutritional interventions and oral vaccines in the developing world (Korpe and Petri, 2012).
