An outbreak of acute diarrheal disease in a village in Chhattisgarh India was investigated through personal interviews of all households. Spot maps were drawn of the water supply system, sewage, hamlets and area with observed fecal contamination of soil within and around the village. Five clusters of household were selected purposively. One from each hamlets of the village. House to house rapid survey was carried out using pre-structured schedule. Diarrheal disease occurred uniformly throughout the village without clustering in any area. All ages and both sexes were affected, age group 15-44 year and above 60 year persons were more affected. Water samples collected for microbiological examination after instituting control measures showed high coliform counts. Chlorine level in the water examined was found to be inadequate to decontaminated common pathogens. Local cultural practices were followed by people such as indiscriminate defecation in public places, washing clothes and cleaning utensils from water sources where the community collected its drinking water. Storage of cow dung adjoining to the water resources and maintenance of water supply system was the risk factors that could have contributed to this outbreak.
