| 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。 |
