摘要
目的 调查一起幼儿园急性上呼吸道感染暴发疫情,为今后处理类似疫情积累经验。方法 搜集所有病例的流行病学资料、临床资料,以及实验室检测结果等,并对调查结果进行统计学分析。结果 幼儿园教职工罹患率为56.92%（37/65）,没有幼儿病例。病例的症状主要表现为咽红、咽痛、乏力、发热及急性扁桃体炎等。饮用酸奶是主要发病危险因素（OR=3.34,95%CI：1.08~10.32）。病例咽拭子中检出停乳链球菌似马亚种,检出率为76.92%（10/13）。结论 停乳链球菌似马亚种是此次食物中毒的病原菌。由食物中食源性停乳链球菌似马亚种引起的急性上呼吸道暴发感染在国内非常罕见。迅速对病原进行分离和鉴定是确定疫情暴发原因的关键。
Objective To investigate an outbreak of acute upper respiratory tract infection in a kindergarten, and help to better manage the future outbreaks. Methods Epidemiology data, clinical information and laboratory test results of all the cases were analyzed with descriptive epidemic method and statistics method. Results The attack rate of adults were 56. 92% （37/65）. No children got sick. The main symptoms were pharyngeal hyperemia, pharynx aches, fatigue, fever and acute tonsillitis, etc. Drinking yoghourt was the main risk factor （ OR = 3.34, 95% CI： 1.08-10. 32）. The Streptococcus dysgalactiae subspecies equisimilis （SDSE） was detected in the cases＇ pharynx swab samples and the detection rate was 76.92% （ 10/13）. Conclusion SDSE was the pathogen of this food poisoning. The outbreak of acute upper respiratory tract infection with SDSE-contaminated food seldom occurs in China. Isolation and identification of SDSE is the key to its rapid diagnosis.
