This is a summary report of a full systematic review that synthesised evidence on water, sanitation and hygiene (WASH) interventions implemented in the first 12 months of an emergency response. Evidence that WASH interventions reduce disease risk was limited, although reduced transmission risk through the use of chlorine in water was documented most often. There was clear evidence against pumping wells flooded with seawater. The review assessed how community perceptions and preferences affected the success of these interventions. Key factors included the taste and smell of water treatments, a preference for radio and face-to-face communication and ease of use. Five programme design and implementation characteristics were identified in the review as being associated with more effective programmes. They included timing, experienced staff, communication, community-driven engagement and linking development programmes to emergency responses.
This report summarises a systematic review that examines which promotional approaches are effective in changing handwashing and sanitation behaviour and which implementation factors affect the success or failure of such interventions.
Safe water, sanitation and hygiene (WASH) behaviours, such as treating drinking water, washing hands at key times or using a latrine rather than defecating in open spaces, are cornerstones of building strong, healthy communities and reducing mortality due to diarrhoea and other preventable diseases. Many studies have shown the health benefits of WASH, and factors that affect initial adoption of short-term WASH use. Few have assessed the determinants of long-term, sustained WASH practice.
This systematic review summary by Benjamin-Chung and colleagues tries to identify mechanisms that trigger spillover through geographic or social proximity, learning or imitation, norm-shaping, income and substitute effects, general equilibrium effects and relative deprivation.
This report by Lemmi and colleagues is based on a systematic review that looked at the impact of community-based rehabilitation (CBR) on health, education, livelihoods, social inclusion and empowerment.
