In developing countries diarrhea diseases take a big toll which can be prevented by adequate supply of safe drinking water. Thus a longitudinal study was taken up to determine the morbidity due to water borne diseases and bacteriological quality of water. 150 houses in two different areas, one supplied by bore well and other by tap water was selected by modified cluster sampling. Weekly morbidity details collected. Monthly water samples were assessed for bacteriological quality from main supply, household storage and morbidity reported houses. The difference in proportion of potable and non potable water at storage points was statistically significant. The overall incidence rate of target diseases was 3.58%,majority were diaarrhoel diseases with increased incidence in children less than five years.
在发展中国家，腹泻疾病造成了巨大损失，而充足供应安全饮用水可预防此类疾病。因此，开展了一项纵向研究，以确定水源性疾病的发病率和水的细菌学质量。通过改良整群抽样法，在两个不同区域选取了150户家庭，其中一个区域由井水供水，另一个区域由自来水供水。收集每周的发病情况细节。每月从主要供水点、家庭储水处以及报告有发病情况的家庭采集水样，评估其细菌学质量。储水点可饮用水和非饮用水比例的差异具有统计学意义。目标疾病的总体发病率为3.58%，大多数为腹泻疾病，5岁以下儿童的发病率更高。
