摘　　要：目的了解上海浦东新区聚集性发热疫情季节性和病原学特征,为防控策略制定提供科学依据。方法收集2013—2021年上海浦东新区聚集性发热疫情资料,采用集中度法和圆形分布法进行分析。结果2013—2021年浦东新区聚集性发热疫情共109起,小学的报告起数最多,77起(70.64%)。集中度法结果表明,M值为0.59;圆形分布法结果表明,离散度r=0.54,平均角α=357.32°,雷氏Z值为32.07,P<0.05,高峰日为12月28日,高峰时段为10月25日至次年3月3日。浦东新区聚集性发热疫情主要由流感病毒引起;大部分病例为单病原体感染,个别为双重感染;甲型流感病毒在单病原体感染和双重感染中检出率均最高。结论小学是浦东新区聚集性发热疫情防控工作的重点场所,浦东新区聚集性发热疫情具有较强的季节性,10月下旬至次年3月上旬是疫情发生高峰,流感病毒等呼吸道病原体是引发疫情的主要原因。Objective To understand the seasonal and etiological characteristics of the epidemic situation of cluster fever in Pudong New Area,Shanghai,and to provide a scientific basis for the formulation of prevention and control strategies.Methods The epidemic data of cluster fever in Pudong New Area of Shanghai from 2013 to 2021 were collected,and the data were analyzed by concentration degree and circular distribution methods.Results From 2013 to 2021,there were 109 cases of cluster fever reported in Pudong New Area,with primary schools reporting the most cases,77 cases(70.64%).The M value was 0.59.Circular distribution results showed that angle dispersion index r value was 0.54,the average angle was 357.32°,and the average angle of Rayleigh′s test Z value was 32.07.The peak day was December 28,and the peak period was from October 25 to March 3 of the following year.The cluster of fever in Pudong New Area was mainly caused by influenza virus.Most cases were single pathogen infection,and some were double pathogen infection.Influenza A virus had the highest detection rate in both single pathogen infection and double pathogen infection.Conclusion Primary schools are the focus of prevention and control of the cluster of fever in Pudong New Area.The epidemic situation of cluster fever has a strong seasonal characteristic,and the peak of incidence is from late October to early March of the next year.Respiratory pathogens such as influenza virus are the main causes of the epidemic situation.
