Preventing transmission of cholera remains an important priority in many countries and humanitarian settings. This study conducted lab-testing and field-evaluations of some commonly used interventions for reducing cholera’s spread to produce recommendations for WASH practitioners and policymakers.
The purpose of this research was to establish the laboratory efficacy and field effectiveness of under-researched, on-going public health interventions commonly implemented to prevent cholera transmission in humanitarian crises, including:
These interventions are widely implemented in cholera response activities but lack both the fundamental laboratory data on efficacy (e.g. when you spray chlorine on a surface with Vibrio cholerae on it, is the bacteria inactivated?) and field effectiveness (e.g. how effective are programs as implemented in emergency response). This research aimed to fill these evidence gaps using laboratory research methods and mixed-methods field research, including household surveys, key informant interviews, focus group discussions, water quality testing, and household surface testing.
This study was selected by the R2HC for our Impact Case Study series. The case study is now available to view online.View
