【摘要】：目的分析2014-2016年北京市朝陽區(qū)流感聚集性疫情的流行特征,為流感聚集性疫情防控提供科學(xué)依據(jù)。方法收集北京市朝陽區(qū)2014年9月1日-2016年8月31日?qǐng)?bào)告的流感聚集性疫情資料,分析流感聚集性疫情的流行病學(xué)特征和疫情持續(xù)時(shí)間、罹患率的影響因素。結(jié)果 2014-2016年北京市朝陽區(qū)共報(bào)告79起流感聚集性疫情,累計(jì)發(fā)病1 067人,平均罹患率為35.0%。秋冬季疫情高發(fā),流感聚集性疫情均發(fā)生在10月-次年4月。小學(xué)和托幼機(jī)構(gòu)是疫情的高發(fā)場(chǎng)所,共報(bào)告65起(82.3%)。2014-2015年度流感聚集性疫情以A(H3N2)亞型流感病毒為主,占97.1%(34/35)。2015-2016年度以B(Victoria系)流感病毒為主,占79.5%(35/44)。流感聚集性疫情的罹患率與發(fā)生疫情場(chǎng)所平均人口數(shù)(P0.05)有關(guān),持續(xù)時(shí)間與疫情報(bào)告的時(shí)間間隔有關(guān)(P0.001)結(jié)論流感聚集性疫情具有明顯的季節(jié)性,小學(xué)和托幼機(jī)構(gòu)是高發(fā)場(chǎng)所。盡早報(bào)告疫情是控制流感聚集性疫情的關(guān)鍵因素。
[Abstract]:Objective to analyze the epidemic characteristics of influenza agglomeration in Chaoyang District of Beijing from 2014 to 2016, and to provide scientific basis for the prevention and control of influenza agglomeration. Methods collected the data of influenza cluster epidemic reported from September 1, 2014 to August 31, 2016 in Chaoyang District, Beijing, and analyzed the epidemiological characteristics, duration and the influencing factors of attack rate. Results A total of 79 influenza outbreaks were reported in Chaoyang District of Beijing from 2014 to 2016, with a cumulative incidence of 1,067 people and an average attack rate of 35.0 cases. Autumn and winter outbreaks are high, influenza outbreaks are concentrated in October-April of the following year. Primary schools and child-care institutions are the high risk sites for the epidemic, with 65 cases (82.3%) reported. In 2014-2015, influenza A (H3N2) subtype influenza viruses were the dominant type of influenza outbreaks. 97.1% (34 / 35). In 2015-2016, B (Victoria was the predominant influenza virus, accounting for 79.5% (35 / 44). The attack rate of influenza aggregated epidemic was related to the average population of the epidemic site (P0.05), and the duration was related to the time interval of epidemic report (P0.001). Conclusion Influenza clustering epidemic has obvious seasonality. Primary schools and childcare institutions are high risk places. Early reporting of the epidemic is a key factor in the control of influenza agglomeration.
