The WASHmobile Operational Guide provides comprehensive instructions for implementing a mobile health (mHealth) and e-voucher program aimed at preventing diarrhea outbreaks in high-risk communities. Based on evidence from randomized controlled trials in the Democratic Republic of the Congo and Bangladesh, the guide outlines how automated voice and SMS messages - combined with redeemable e-vouchers for chlorine tablets - can significantly improve hygiene practices such as handwashing and water treatment. The program targets both patient households and residents living nearby through location-based alerts, offering a scalable and cost-effective response to disease outbreaks.
This guide is intended for Ministries of Health, NGOs, and other implementers seeking to adapt WASHmobile to their local context.
We recommend piloting this approach in your context before large scale program implementation. For more information on tailoring program delivery and components please reach out to the WASHmobile team on our Contact Us page.
