摘  要:目的分析中国2009年甲型H1N1流感大流行聚集性疫情的流行病学特点。方法对“突发公共卫生事件报告管理信息系统”中报告的甲型H1N1流感聚集性疫情进行描述性流行病学分析。结果截至2010年8月10日,中国报告甲型H1N1流感聚集性疫情2773起(发病77363例,死亡20例),其中学校(包括托幼机构)报告聚集性疫情2498起(占总起数的90.08%),以中学为主(1223起,48.96%)。南方省份的聚集性疫情较多(占总起数的77.03%)。南方省份在2009年6、11月出现两次报告高峰,北方省份仅在9月出现一次报告高峰。结论中国2009年甲型H1N1流感大流行聚集性疫情的分布特点与季节性流感类似,但冬季高峰的起点明显早于季节性流感,且流行强度远超过季节性流感。Objective To study the epidemiological characteristics on the clustering nature of pandemic (H1N1) 2009 in China. Methods Time and place distribution of pandemic (H1N1) 2009 on the nature of clustering through data from Public Health Emergency Management Information System were described. Results As of August 10, 2010, 2773 pandemic (H1N1) 2009 clusters, a total of 77 363 cases (including 20 deaths) were reported in the mainland of China. The most reported number of clusters was from schools and kindergartens with the total number of 2498 (accounted for 90.08% of the total number). Middle schools appeared the have the most clusters (1223, accounting for 48.96% ). The number of clusters reported in the southern provinces (cities) accounted for 77.03% of the total, and was more than that in the northern provinces (cities). Two reported peaks in the southern provinces (cities) were in June and November, 2009, respectively. There was only one reported peakin the northern provinces in September, 2009. Conclusion Time and place distribution characteristics on the clusters of pandemic (H1N1) 2009 were similar to the seasonal influenza, but the beginning of winter peak was much earlier and intensity of reporting was much higher on the clusters of pandemic (H 1N 1 ) 2009 than that of seasonal influenza.
