There is a widespread and deep-rooted belief that diarrhea is part of growing up and cannot be prevented. Working with the government and with non-governmental organizations, the Water and Sanitation Program (WSP) sought to increase rates of handwashing with soap among women and children, especially at critical junctures. This learning note documents the development of the project, with a focus on how it was designed, implemented, and monitored. Challenges and lessons learned are highlighted to assist program managers in designing and managing evidence-based handwashing with soap and other hygiene promotion programs.CC BY 3.0 IGOADVERTISINGBACKBONEBEHAVIOR CHANGECAREGIVERSCOMMUNICATION CAMPAIGNCONDOMSDIARRHEADIARRHEAL DISEASESFACT SHEETGENERAL POPULATIONHANDWASHINGHEALTH CENTERSHYGIENEHYGIENE INTERVENTIONSHYGIENE ISSUESHYGIENE PROMOTIONHYGIENE PROMOTION PROGRAMSIDIMAGEIMPLEMENTING AGENCIESIMPLEMENTING AGENCYINFORMATION GAPSINSTITUTIONINTERPERSONAL COMMUNICATIONLEARNINGLITERACYLOCAL AUTHORITIESLOCAL GOVERNMENTSMALARIAMARKETINGMASS MEDIAMORTALITYMOTHERNATIONAL GOVERNMENTNATIONAL GOVERNMENTSNUMBER OF PEOPLEPHONEPOSTERSPRIMARY SCHOOLPRIMARY SCHOOL-AGE CHILDRENPRIVATE PARTNERSHIPPRIVATE SECTORPROGRESSRADIORADIO COMMUNICATIONREPRODUCTIVE AGEREPRODUCTIVE HEALTHRESPECTRESULTSRURAL AREASRURAL WOMENSANITATIONSANITATION SERVICESSCHOOL-AGE CHILDRENSOAPSOCIAL NORMSSOCIAL SUPPORTSUPERVISIONSUSTAINABLE ACCESSTARGETSTECHNICAL ASSISTANCETECHNICAL SUPPORTTELEVISIONTRANSPORTATIONUSESUSING SOAPWASH HANDS WITH SOAPWASHING HANDSWOMANWorld Bank10.1596/11683
