WASH 5 Star approach: addressing hygiene behaviour in schools of rural Bangladesh MukherjeeSanjoy AlamMd. Moksad 2018 Every child has basic rights to safe drinking water, sanitation and hygiene (WASH). School are essential institutions to children’s welfare, and a place where lifelong behaviours are inculcated. The National Hygiene Baseline Survey [1] and recent WASH bottleneck analysis of Bangladesh [2] reflected the worrying state of hygiene behaviour in schools. WaterAid Bangladesh has developed an approach called ‘WASH 5 Star’ based on the five behavioural domains articulated in the National Hygiene Promotion Strategy (NHPS) 2012 in Bangladesh [3] to raise awareness at the individual, household and institutional level on proper hygiene practices . The WASH 5 Star approach was introduced in 2500 schools in rural Bangladesh and yielded encouraging results within a short span of time. This approach can to be introduced at a large scale to achieve wider health benefits.
