摘　　要：目的分析2019—2023年深圳市副流感聚集性疫情监测结果及流行特点,为呼吸道病毒防控提供科学参考。方法收集深圳市2019—2023年副流感聚集性疫情监测的流行病学资料和实验室检测结果,应用描述性统计学方法分析副流感聚集性疫情监测数据。结果2019—2023年深圳市共确诊了15起副流感聚集性疫情,2023年疫情数最多为6起,其次是2021年4起,发病总人数为118人,平均罹患率为17.85%。80.00%的副流感疫情发生在幼儿园,其余发生在中小学校。副流感疫情报告最多的月份是9月(4起,占26.67%),其次是11月和12月(均为3起,占20.00%)。在15起副流感疫情中共采集了100份咽拭子样本,经检测呼吸道病毒阳性共68份,阳性率为68.00%,其中副流感病毒阳性49份,其它呼吸道病毒阳性22份(3份为2种病毒阳性)。15起副流感疫情中,11起由1型副流感病毒引起(占73.34%,5起为1型单独引起,6起为1型与其它呼吸道病毒混合感染引起),2起由2型单独引起(占13.33%),2起由3型单独引起(占13.33%)。结论幼儿园是副流感病毒疫情发生高发场所,需在幼儿园和学校等集体单位加强副流感病毒疫情的监测工作,与其它亚型相比,1型副流感病毒引起了更多的聚集性疫情,在监测中需特别关注,深圳市副流感疫情的高发季节是秋季和冬季。Objective To understand the epidemiological characteristics of parainfluenza outbreaks in Shenzhen from 2019 to 2023,so as to provide scientific evidence for prevention and control of respiratory viruses.Methods The epidemiological data and test results of parainfluenza outbreak surveillance from 2019 to 2023 were collected.The descriptive epidemiological methods were used to analyze the parainfluenza outbreak surveillance data.Results A total of 15 parainfluenza outbreaks were identified during 2019-2023.The highest number of outbreaks was 6 in 2023 followed by 4 outbreaks in 2021.The total number of cases were 118 and the average attack rate was 17.85%.For the parainfluenza outbreaks,80.00% occurred in kindergartens while the rest occurred in primary or middle schools.The monthly reports of outbreak was the highest in September(4 events,26.67%),followed by November and December(in average 3 events,20.00%).A total of 100 throat swab samples were collected from the 15 outbreaks.Sixty-eight samples were tested positive for respiratory viruses and the positive rate was 68.00%,Among the positive samples,47 were positive for parainfluenza,22 for other respiratory viruses(including 3 positive for two respiratory viruses).Among the 15 outbreaks,11 were caused by parainfluenza type 1(accounting for 73.34%,including 5 outbreaks by parainfluenza type 1 alone and 6 by parainfluenza type 1 and other respiratory viruses),2(accounting for 13.33%)by parainfluenza type 2 alone and 2(accounting for 13.33%)by parainfluenza type 3 alone.Conclusions Kindergarten was the high risk place of parainfluenza outbreak.Surveillance of parainfluenza outbreaks should be reinforced in kindergartens and schools.Comparing to other types of parainfluenza,parainfluenza type 1 caused more outbreaks and should be focused in the surveillance.The peak time of parainfluenza outbreaks in Shenzhen were autumn and winter.
