Hand Washing Promotion for Preventing Diarrhea
Description of Resource:
Diarrhea causes many deaths in children under age 5, mostly in low- and middle-income countries (LMICs). Hand washing after defecation, after cleaning a baby's bottom, and before preparing and eating food can reduce the risk of diarrhea. This Cochrane Review summarized trials evaluating the effects of promoting hand washing on the incidence of diarrhea among children and adults in day-care centers, schools, communities, or hospitals. This review identified 22 trials conducted in both high-income countries and LMICs. Hand washing promotion strategies were found to be effective in child day-care facilities, schools and hospital settings. Hand washing promotion may reduce the incidence of diarrhea by about 30%. However, less is known about how to help people maintain hand washing habits in the longer term.
