摘　　要：目的:对成都市某幼儿园一起人类偏肺病毒感染疫情进行分析,以期为相关疫情防控提供参考。方法:回顾性分析2022年6月成都市某幼儿园发生的一起疫情,探讨传染源、传播链等内容。结果:14例病例呈班级聚集性,发病时间持续5天,6月21日发病1例、22日2例、23日7例、24日4例、25日1例,发病高峰集中在6月23—24日;所发热、咳嗽13例,扁桃体肿大8例,咽部充血7例,咳痰4例;临床诊断为急性支气管炎5例、急性上呼吸道感染3例、细菌性感染2例、急性扁桃体炎1例、肺炎1例,另外2例发病儿童暂未就诊;不同性别患病率差异无统计学意义(χ^(2)=0.486,P>0.05);采集发热病例咽拭子3份,检测阳性率为100.00%。结论:结合病例的临床症状及实验室检测结果,该疫情可定性为一起人类偏肺病毒感染引起的聚集性发热疫情。适时停课对于学校疫情虽是最有效的防控措施,但实际难度很大;除了采取加强消毒、暂停集体活动、健康宣传等措施外,勤洗手、佩戴口罩是最有效的预防手段。OBJECTIVE Retrospective analysis of one case of human metapneumovirus infection in a certain kindergarten to provide reference for related epidemic prevention and control.METHODS Analyze a clustered epidemic that occurred in June 2022,and use retrospective analysis of epidemiological data to analyze the relationship between the source of infection,transmission chain,and other factors.RESULTS Four cases showed class clustering,with a duration of 5 days.On June 21st,there was 1 case,2 cases on June 22nd,7 cases on June 23rd,4 cases on June 24th,and 1 case on June 25th.The peak incidence was concentrated from June 23rd to 24th;All cases had fever,cough in 13 cases,tonsil enlargement in 8 cases,pharyngeal congestion in 7 cases,and phlegm in 4 cases.Clinical diagnosis included 5 cases of acute bronchitis,3 cases of acute upper respiratory tract infection,2 cases of bacterial infection,1 case of acute tonsillitis,and 1 case of pneumonia.The other 2 affected children have not yet sought medical attention;There was no significant difference in the attack rate rate between the sexes(χ^(2)=0.486,P>0.05).A total of 3 throat swab samples from 3 fever cases were collected,and 3 cases of human metapneumovirus were detected,with a positive rate of 100.00%.CONCLUSION The initial symptoms of this clustered epidemic ware fever and other related factors.Based on clinical symptoms and laboratory testing results,it is classified as a“clustered fever epidemic caused by human metapneumovirus infection”.For the school epidemic,timely suspension of classes is the most effective prevention and control measure,but the actual difficulty is great.In addition to strengthening disinfection,suspending collective activities,and health promotion measures,frequent hand washing and wearing masks are the most effective prevention measures.
