【摘要】： 目的：分析一起细菌性痢疾暴发的原因，，进而对细菌性痢疾暴发采取控制措施，为今后现场处置疫情方法提供参考。方法：运用目前的现场流行病学调查方法，对2005年6月3日至6月24日一农村城镇108例腹泻病例进行调查，现场查看城镇卫生环境、了解居民聚餐饮用水情况、询问腹泻病人临床表现、查看门诊日志、确定病例定义、采用病例对照研究、排查供水管网破漏情况，同时采取饮用水样、患者粪便标本进行细菌学培养、检测。结果：本次疫情是一起由主要供水管网破漏、饮用水被垃圾持续污染引起的细菌性痢疾暴发，经实验室检测病原菌是福氏志贺氏菌，血清型为3a，采取更换破漏输水管道、饮用水消毒、蓄水池改造以及对居民健康教育等综合防治措施，疫情得到控制。结论：保障农村地区生活饮用水质量，避免受到污物污染。在肠道传染病高发季节应加强饮用水的监测。
[Abstract]:Objective: to analyze the causes of an outbreak of bacillary dysentery, and then to take control measures for the outbreak of bacillary dysentery. Methods: a total of 108 cases of diarrhea in a rural town from June 3rd 2005 to June 24th were investigated by using the method of field epidemiological investigation. The clinical manifestations of patients with diarrhea were inquired, the log of outpatients was checked, the definition of cases was determined, the case control study was used to check the leakage of water supply networks, and the samples of drinking water and feces were collected for bacteriological culture and detection. Results: this epidemic situation is an outbreak of bacillary dysentery caused by the leakage of the main water supply network and the persistent pollution of drinking water by garbage. The pathogenic bacteria tested by the laboratory is Shigella flexneri and the serotype is 3a. The epidemic situation was brought under control by comprehensive prevention and treatment measures such as disinfection of drinking water, reconstruction of cisterns and health education for residents. Conclusion: the quality of drinking water in rural areas should be guaranteed, and the monitoring of drinking water should be strengthened in the season of high incidence of intestinal infectious diseases.
