WASHmobile Example mHealth Messages

Through mobile health (mHealth) messaging, WASHmobile delivers timely reminders and motivational messages to promote water treatment, safe water storage, and handwashing with soap among households at highest risk for diarrheal disease.

This page features examples from our RCTs in Bangladesh and the DRC, including climate-resilient mobile messages tailored to help families protect their health during floods, droughts, and other extreme weather events.

Messages are sent through our partnership with engageSPARK, a mobile scheduling and delivery platform that enables large-scale health communication in low-connectivity settings.

I have Mwanza, the mother of a young child that came to the hospital with cholera, here with me today. Mwanza, Can you tell us how you prepare soapy water for your family?

Mwanza: To make soapy water, I use the leftover soap from when I wash clothes. I cut it up into same pieces and put it in an empty bottle, then I add water, then shake it to mix the water and soap, and we then use it to wash our hands with soap. We always wash our hands with soap at the 5 key times you taught us: After defecation, after cleaning a child’s feces or anus, before preparing food, before eating, and before feeding children.
Dr. Picha: Wonderful Mwanza. Thank for listening to us today. Please be sure to always prepare soapy water for your family and to encourage everyone in your family to wash their hands with soap. Share my message. Have a good evening.
