Diarrhoea is a common water-borne disease among slum children in Bangladesh. This study seeks to identify the engineering, behavioural and socio-economic determinants of childhood
diarrhoea and its duration and to compute the resulting costs borne by slum dwellers. The study is based on a survey of 480 households in 32 slums in Dhaka. Nearly 50 percent of slum
households reported diarrhoea episodes during the recall period of 15 days, with an average duration of 3.76 days of diarrhoea.
