Cholera-Hospital-Based-Intervention-for-7-days

The CHoBI7 health facility program focuses on promoting handwashing with soap and water treatment to diarrhea patients and their household members during the one-week period after the patient is admitted to the health facility, when their household is at highest risk for diarrheal diseases. The CHoBI7 program includes: (1) a WASH pictorial module delivered by a health worker bedside to diarrhea patient and their household members in a health facility on handwashing with soap, water treatment, and safe water storage; and (2) a diarrhea prevention package containing chlorine tablets for water treatment, a soapy water bottle (water and detergent powder), a handwashing station, and a water vessel with a lid and tap for safe drinking water storage. Households are instructed to boil their water once their supply of chlorine tablets is completed.

The CHoBI7 mHealth (mobile health) program targets five key behaviors: (1) preparing soapy water using water and detergent powder; (2) handwashing with soap at food and stool related events; (3) treating household drinking water using chlorine tablets during the one week high risk period after the diarrhea patient in the household was admitted to the health facility; (4) safe drinking water storage in a water vessel with a lid and tap; and (5) heating of household drinking water until it reaches a rolling boil after the one week high risk period. Participant households receive bi-weekly voice and text messages from the CHoBI7 mHealth program over a 12-month period. These mobile messages are sent using the VIAMO platform (www.viamo.io).

The CHoBI7 home visit program involves two, 30-minute home visits conducted during the week after the index diarrhea patient was recruited at the health facility. A health worker reinforces the content of the CHoBI7 health facility program in the participant's home.
