The findings from previous recent randomized controlled trials of The Cholera Hospital Based Intervention for 7 Days (CHoBI7) demonstrated that this intervention was effective in significantly reducing symptomatic cholera infections, diarrheal disease, and stunting among young children in intervention households, and had significant sustained impacts on handwashing with soap behaviors and improved water quality 12 months post intervention. Therefore, the investigators next step in the transition to scale is to: (1) To tailor the CHoBI7 program for delivery in rural health facilities and market test the CHoBI7 Program to determine the feasibility of providing a modified water, sanitation, and hygiene (WASH) package with only a soapy water bottle and chlorine tablets in both urban and rural settings through formative research and engagement of key stakeholders (Formative Research Phase); and (2) To evaluate the effectiveness of delivering the CHoBI7 program in district hospitals and sub-district health complexes in rural areas in terms of increases in WASH behaviors and decreases in diarrheal disease by conducting a randomized controlled trial (RCT) (Intervention Implementation and Evaluation Phase).
