中文摘要:
      目的分析成都市某医院一起扁桃体炎暴发疫情的原因、传播途径及危险因素。方法采用病例对照研究进行现场流行病学调查,利用自制问卷面对面调查收集可能的危险因素,通过非条件logistic L01归方法进行单因素和多因素分析。结果该次疫情共发病74例,以20~30岁青壮年为主,女性多于男性,集中在8月20--22日发病,且均为医院员工,以医生和护士为主,无住院患者发病。患者空间分布以手术室、麻醉科和外科相关科室居多(71.62%,53/74),其中39.19%(29/74)分布于手术室和麻醉科。logistic回归分析显示,8月19日进人配餐问午餐为暴露的危险因素(OR=6.67,95%C1:1.92。23.23)。采集患者咽拭子细菌培养分离出6溶血性链球菌。结论该次疫情为一起B溶血性链球菌感染引起医院内急性扁桃体炎暴发,8月19日进入配餐问午餐为暴发疫情的危险因素,不排除食源性和飞沫途径传播。
英文摘要:
      Objective To investigate an outbreak of beta·hemolytic streptococcal tonsillitis in a hospital.Methods A case.control study was conducted with a self-made questionnaire to collect the risk factors,Univariate and multivariate logistic regression model were used to explore the relationship between risk factors and:aaorbidity.Results 74 cases were occurred during the outbreak with patients aged mainly between 20-30 and more females than males.Most cases appeared abrupt onset between Aug.,20-22.All the patients were hospital workers,with majority as nurses and doctors from the operating room.department of anesthesiology and surgical related departments(7 1.62%). All patients shared the same experience---eating lunch in the dining room on Aug 1 9(odds ratio 6.67. 95%confidence interval 1.92-23.23).Beta-hemolytic streptococci was observed from cultures of the throats from the patients.Conclusion The outbreak was an explosive epidemic of tonsillitis in a hospital,caused by beta-hemolytic streptococci.Food provided from the dining room attached to the operating theater on August,19 seemed to be the risk factor.
