Hand washing promotion for preventing diarrhoea
Interventions to promote handwashing, such as targeted education and provision of free soap, improve hand hygiene and reduce diarrhoeal episodes in children and adults living in low- and middle-income countries by about one third. This significant reduction is comparable to the effect of providing clean water in low-income areas.
Hand washing after defecation and handling faeces, and before preparing and eating food, is one of a range of hygiene promotion interventions that can interrupt the transmission of diarrhoea-causing pathogens. This review evaluates the effects of interventions to promote hand washing on diarrhoeal episodes in children and adults.
