Develop a scalable approach for delivering water, sanitation, and hygiene (WASH) messages to households in areas with confirmed cholera patients in Dhaka, Bangladesh. This will be done by conducting formative research through in-depth interviews, focus group discussions, and intervention planning workshops with households in areas with confirmed cholera patients and government officials to identify perceptions of WASH behaviors and to inform the development of a mobile health intervention (mHealth) for this population. This intervention approach will then be piloted in a subset of households, and revised according to feedback. Then the investigators will conduct a randomized controlled of the refined mHealth intervention.
