Brief Summary

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.

Study Arms (2)

CHoBI7 mHealth program Arm

EXPERIMENTAL

The first arm will receive the CHoBI7 mHealth program and a general message on oral rehydration solution (ORS) (CHoBI7 mHealth program Arm) .

Behavioral: CHoBI7 mHealth program Arm; Behavioral: general message on oral rehydration solution (ORS)

Interventions

CHoBI7 mHealth program Arm BEHAVIORAL

We will start delivery of this intervention with a pictorial module delivered in the home during two 30 minute visits on cholera transmission and prevention after enrollment. Households will be provided a handwashing station, a covered water vessel, and chlorine tablets. Households will then receive the CHoBI7 WASH mHealth program voice and text messages on handwashing with soap and water treatment bi-weekly.
