摘要

摘要: 目的分析2017—2023年深圳市幼儿园和学校人偏肺病毒聚集性疫情监测结果及流行规律，为呼吸道病毒防控提供科学参考。方法基于流感监测网络平台上收集的深圳市幼儿园和学校2017—2023年人偏肺病毒聚集性疫情流行病学资料和实验室检测结果，采用Mann Kendall检验对人偏肺病毒疫情进行趋势分析。结果 2017—2023年深圳市共确诊11起发生在幼儿园和学校的人偏肺病毒聚集性疫情，2020年疫情数最多(4起)，其次是2018年2起发病总人数为128例，平均罹患率为26.61%。72.73%(8起)的人偏肺病毒疫情发生在幼儿园，27.27%(3起)发生在小学。人偏肺病毒疫情报告最多的月份是12月和3月(均为3起，占27.27%)，其次是4月和6月(均为2起，占18.18%)。在11起人偏肺病毒疫情中共采集98份咽拭子样本，经检测呼吸道病毒阳性共80份，阳性率为81.63%；其中仅人偏肺病毒阳性67份，仅其他呼吸道病毒阳性10份，人偏肺病毒合并其他呼吸道病毒阳性3份。11起人偏肺病毒疫情中，6起由人偏肺病毒单独引起，5起为人偏肺病毒与其他呼吸道病毒混合感染引起。去除2020年数据后，2017—2023年人偏肺病毒疫情数在流感样病例疫情中的占比有随着年份增多的趋势(Z=2.25，P=0.02)。结论 2017—2023年深圳市幼儿园和学校每年均报告人偏肺病毒疫情，大部分人偏肺病毒疫情发生在幼儿园，且高发季节是春季和冬季。

Abstract: Objective To analyze the monitoring results and characteristics of human metapneumovirus (HMPV) outbreaks in Shenzhen in kindergartens and schools during 2017-2023, so as to provide a evidence for prevention and control of respiratory diseases. Methods Based on the epidemiological data and laboratory test results of HMPV outbreaks in kindergartens and schools of Shenzhen during 2017 to 2023, collected from the influenza monitoring network platform, Mann Kendall test was applied for trend analysis pf HMPV. Results A total of 11 HMPV outbreaks were identified in kindergartens and schools from 2017 to 2023 for 128 cases with an average incidence rate of 26.61% in 2018. The most yearly HMPV outbreaks were reported in 2020 being 4 outbreaks, followed by 2 outbreaks in 2018. A total of 72.73% (8 outbreaks) of HMPV outbreaks were identified in kindergartens with 27.27% (3 outbreaks) occurring in primary schools. The monthly greatest count of outbreak was 3(27.27%) in March and December, followed by 2 outbreaks (18.18%) in April and June. A total of 98 swab samples were collected, and 80 samples were positive for respiratory viruses with a positive rate of 81.63%; among them, 67 samples were positive for HMPV alone, 10 samples were positive for other respiratory viruses alone, and 3 samples were positive both for HMPV and other respiratory virus. Among the 11 human metalung virus cases, 6 HMPV outbreaks were caused by human metapneumovirus alone, and 5 outbreaks were caused by HMPV and other respiratory viruses. Except for 2020, the percentage of HMPV outbreaks in influenza like illness outbreaks increased with year (Z=2.25, P=0.02). Conclusion HMPV outbreaks have been reported every year from 2017 to 2023 in kindergartens and schools in Shenzhen, most of HMPV in kindergartens, and the peak seasons of HMPV outbreaks are spring and winter.
