WASH Interventions in Disease Outbreak Response: Evidence Synthesis.

Publication year
2017
Country

This evidence synthesis identifies, synthesizes and evaluates existing evidence of the impacts of water, sanitation, and hygiene (WASH) interventions in disease outbreaks in 51 humanitarian contexts in 19 low and middle-income countries. The research team developed theories of change for the WASH interventions under consideration, documenting the theoretical route from intervention activities to outputs, outcomes, and impacts. WASH interventions consistently reduce both the risk of disease and the risk of transmission in outbreak contexts.

Water,  sanitation,  and  hygiene  are  one  part  of  a  cholera  control  strategy.  Household  water  treatment  (HWT)  in  particular  has  been  shown  to  improve  the  microbiological  quality  of  stored  water  and  reduce  the  disease  burden.  We  conducted  a  systematic  review  of  published  and  gray  literature  to  determine  the  outcomes  and  impacts  of  HWT  in  preventing  cholera  specifically.  Fourteen  manuscripts  with  18  evaluations  of  HWT  interventions  in  cholera  were  identified.  Overall,  a  moderate  quality  of  evidence  suggests  that  HWT  int
