Abstract: Due to the increasingly documented prevalence of diarrhoeal diseases in Malaysia, a number of water-related programmes have been implemented in an attempt to improve health status through the reduction of incidence of waterborne communicable diseases associated with poor public water supplies. The implicit assumption underlying these projects is that the enhancement of the physical infrastructure, and subsequent improvements in the quality of the water supply, will substantially reduce water-related disease. The present study questions this hypothesis and uses a socio-ecological model as a framework to assess risk factors associated with the increased probability of waterborne disease. Research is centered on Port Dickson, a district which typifies existing water and sanitation conditions in much of semi-rural Malaysia. Health services utilization data and a 268-household diarrhoeal morbidity survey were used to measure the burden of illness of waterborne disease within the district and to identify predictors of morbidity. It was concluded that although treatment facilities will reduce the health burden in the region, a number of behavioural and sanitation factors may be more important and could act to minimize the potential impacts of improved water quality.
