Summary

This study tests a program called CHoBI7, which teaches handwashing, water treatment, and safe water storage to diarrhea patients and their families in Bangladesh hospitals. Researchers want to see if this program reduces diarrhea and improves hygiene behaviors compared to standard advice. The trial involves 1,600 participants and focuses on households with young children and no running water.
