夏秋季散发感染性腹泻发病原因的病例对照研究

摘要

目的：探究夏秋季感染性腹泻发生的原因及防范措施。方法选取我市2013年8月1日～2013年9月30日发现的感染性腹泻病患36例为病例组，同时选择在该科住院的其它疾病患者36例为对照组，分析两组病例病前3 d的饮食、饮水及水源供应情况。结果病前3 d有饮用可疑污染水：病例组36例，对照组0例，经检验差异具有统计学意义（P＜0.05）；饮用自来水者7例，占19.4%；自备水者13例，占36.1%；二次供水者16例，占44.4%。水质细菌学指标：管网水3/15、二次供水8/15、自备水8/11。在细菌指标超标的样品中，细菌总数最高高出国家规定标准的7倍。总大肠杆菌最高高出国家规定标准的1600倍。结论饮用水污染是导致夏秋季感染性腹泻的主要原因。%Objective Exploring the causes and preventive measures of infectious diarrhea in summer and autumn occurred.Methods Chose infectious diarrhea patients the city August 1 2013 to September 30 2013 found 36 cases for the case group,and selected 36 cases other diseases that hospitalized in the control group,the two groups were analyzed disease the first three days of eating,drinking water and water supply.ResultsThree days before the disease had contaminated drinking water suspicious: case group of 36 patients in the control group,0 cases. Statisticaly significant(P<0.05)by testing difference,drinking water in 7 cases,accounting for 19.4%,owned water 13 cases,accounting for 36.1%,secondary water supply in 16 cases,accounting for 44.4%. Bacteriological water quality indicators: water pipe 3/15,8/15 secondary water supply,water supplied 8/11. In bacterial indicators exceeded samples,the highest total number of bacteria was up seven times the national standard. E. highest total was up 1 600 times the national standard.Conclusion Drinking water polution is the cause of infectious diarrhea in summer and autumn the main reason.
