This Working Paper is one in a series of knowledge products designed to showcase project findings, assessments, and lessons learned in the Global Scaling Up Handwashing project. This paper is conceived as a work in progress to encourage the exchange of ideas about development issues.
Global Scaling Up Handwashing is a project by the Water and Sanitation Program (WSP) focused on applying innovative behavior change approaches to improve handwashing with soap among women of reproductive age (15–49 years) and primary school-age children (5–9 years). It was implemented by local and national governments with technical support from WSP in four countries: Peru, Senegal, Tanzania and Vietnam.
