About

BACKGROUND. Diarrhea is ubiquitous, particularly among people in low- and middle-income countries. Unsafe drinking water, poor sanitation, and insufficient hygiene are responsible for nearly 90% of diarrhea-related mortalities. Despite extensive knowledge that has been obtained in recent years, there is no consensus as to the most efficacious approach to improve Water, Sanitation, and Hygiene behavior and health. With this study, we want to determine whether multi-faceted contextualized and non-contextualized WASH interventions have a differential impact.

OBJECTIVES. The primary objective is to determine the effectiveness of a contextualized and non-contextualized add-on intervention for improving hand washing (HW) behavior. Secondary objectives include the impact on latrine use, health, coverage of HW and latrine infrastructure, quality of life, and cost-effectiveness.
