本课题采用了横断面和改水前后自身对照的调查方法,研究了农村改水与人群肠道传染病的关系。结果为,改水后的自来水大肠菌群合格率明显提高、供水区人群肠道传染病发病率明显降低,且差异均极显著。说明农村改水具有提高饮用水质、降低人群肠道传染病发病率的良好社会效益。
This project uses cross-sectional and self-control survey before and after water diversion to study the relationship between water diversion and intestinal infectious diseases in rural areas. As a result, the coliform passing rate of tap water after water diversion was significantly improved, and the incidence of intestinal infectious diseases in water supply areas was significantly lower with significant differences. This shows that rural water improvement has the good social benefits of improving the quality of drinking water and reducing the incidence of intestinal infectious diseases in the population.
