目的:分析一起医院外霍乱疫情事件的流行病学特征和控制效果,为预防和控制霍乱等肠道传染病提供依据。方法:采用流行病学调查方法,结合临床症状和实验室监测等调查2016年10月4日-10月10日某地一起感染霍乱的所有患者。结果:该疫情从发病之日排查疑似人员185名,其中5人确诊为霍乱,所有病例均有不同程度的腹泻,无死亡病例。采集肛拭纸5份,均检测出霍乱弧菌。所有病人均收治感染科,其中2名病重患者收治ICU。通过采取积极有效的措施,此次疫情得到有效控制。结论:该事件由一名从事餐饮的家政人员携带霍乱弧菌为传染源,在聚众聚餐时感染发病。霍乱是一种烈性的甲类肠道传染病,水源为主要的传染源,人群普遍易感。控制传染源,切断传播途径为其最主要的防控措施,加强新入院患者的预检分诊流程和住院患者的传染病筛查,落实病区消毒隔离措施,防止医院内霍乱爆发。 Objective: To analyze the epidemiological characteristics and control effects of a cholera epidemic outside the hospital, and provide the basis for prevention and control of intestinal infectious diseases such as cholera. METHODS: All patients infected with cholera in a certain area from October 4 to October 10, 2016, were investigated using epidemiological investigation method, combined with clinical symptoms and laboratory monitoring. Results: The outbreak was quarantined from the date of onset of suspected staff of 185, of which 5 were diagnosed as cholera, all cases have varying degrees of diarrhea, no deaths. Collect anal swab 5 copies, were detected Vibrio cholerae. All patients were admitted to the Department of Infectious Diseases, including two seriously ill patients admitted to the ICU. By taking positive and effective measures, the outbreak has been effectively controlled. Conclusion: The incident was carried by a domestic worker carrying food and drink carrying Vibrio cholerae as a source of infection during the meal gathering. Cholera is a potent type A intestinal infectious disease, water as the main source of infection, the general population susceptibility. To control the source of infection and cut off the route of transmission is the most important prevention and control measure. The pre-screening triage process of newly admitted patients and inpatient screening of infectious diseases should be strengthened, and disinfection and isolation measures should be implemented to prevent the outbreak of cholera in the hospital.
