摘要
目的：分析2005－2013年我国流感暴发疫情的流行病学特征。方法针对2005－2013年全国通过“突发公共卫生事件报告管理信息系统”和“中国流感监测信息系统”中报告的发病10例及以上的流感样病例暴发，根据实验室检测结果判定其中的流感暴发疫情，并对引起流感暴发的病毒型/亚型及暴发的时间、地区、场所分布、规模进行描述性流行病学分析。结果2005－2013年全国共报告流感样病例暴发疫情3252起，其中经实验室确认的流感暴发2915起，以甲型H1N1流感和乙型流感为主。流感暴发病例中以2009－2010年甲型H1N1流感大流行期间报告最多，其他季节主要集中于冬春季，在学校寒暑假期间迅速减少。南方省份报告的流感暴发较多，占总起数的79%。流感暴发的最主要场所为中小学校，报告暴发疫情2763起（占总起数的85%），暴发规模以30～99例为主。结论我国每年冬春流感流行季节发生大量流感暴发疫情，病毒型别存在季节间差异，中小学校是流感暴发的重点场所。
Objective To understand the epidemiological characteristics of influenza outbreaks in China from 2005 to 2013. Methods The data of influenza-like illness outbreaks involving 10 or more cases were collected through Public Health Emergency Management Information System and National Influenza Surveillance Information System in China,and the influenza outbreaks were identified according to the laboratory detection results. Descriptive epidemiological analysis was conducted to understand the type/subtype of influenza virus and outbreak time,area,place and extent. Results From 2005 to 2013,a total of 3 252 influenza-like illness outbreaks were reported in the mainland of China,in which 2 915 influenza outbreaks were laboratory confirmed,and influenza A（H1N1） pdm09 virus and influenza B virus were predominant. More influenza outbreaks were reported in the influenza A（H1N1）pandemic during 2009-2010. Influenza outbreaks mainly occurred during winter-spring,and less influenza outbreaks occurred in winter and summer vocations of schools. More influenza outbreaks were reported in southern provinces,accounting for 79% of the total. Influenza outbreaks mainly occurred in primary and middle schools,where 2 763 outbreaks were reported,accounting for 85% of the total. Averagely 30-99 people were involved in an outbreak. Conclusion A large number of influenza outbreaks occur during influenza season every year in China,the predominant virus type or subtype varies with season. Primary and middle schools are mainly affected by influenza outbreaks.
