１９９７年４月某大学二次供水蓄水池被生活污水污染，引起一起新型成人轮状病毒感染暴发，发病１０５９人，污染水源供水区人群感染率为３５．５６％。多数病例有发热（７９．２６％）和胃肠道症状（７７．４０％），临床症状较重。经调查，二次供水蓄水池与污水设施的距离及污水井工程均不符合卫生要求。加强预防性卫生监督是避免事故的根本保证。
In April 1997, a secondary water supply reservoir in a certain university was polluted by domestic sewage, causing a new outbreak of adult rotavirus infection, with a total incidence of 1059 people. The infection rate of people in contaminated water supply areas was 35.56%. Most cases have fever (79.26%) and gastrointestinal symptoms (77.40%), the clinical symptoms were severe. After investigation, the distance between the secondary water supply reservoir and the sewage facilities and the sewage well works did not meet the hygiene requirements. Strengthening preventive sanitation supervision is the fundamental guarantee to avoid accidents.
