In February 2010, during a workshop organized by BRAC, WaterAid, IRC and the Water Supply and Sanitation Collaborative Council, 50 hygiene practitioners and researchers from South and South East Asia came to together to share lessons learned, and discuss progress and challenges in promoting hygienic behaviours. Eighteen papers were presented and discussed, representing a range of experiences. Considerable progress has been made in research, in improving knowledge about hygiene, and, partially, in improving hygienic practices. In five of the programmes represented at this workshop, hygiene promotion is being implemented at scale with more than one million people. The detailed discussions led to nine recommendations, presented on the document. The papers of the workshop can be found in our resource section.
