摘　　要：目的 分析江苏省2010-2014年间流感样病例的流行病学特征,揭示流感流行特点并制定防控策略。方法 依据《全国流行性感冒（甲型H1N1流感）监测工作方案》,采集流感哨点医院流感样病例（influenza-like illness,ILI）就诊数,对病例咽拭子进行流感病毒核酸检测和病毒分离,结果录入国家流感网络监测系统,利用Excel2007和PASW 18.0对数据进行统计分析。结果 2010-2014年间共报告ILI病例123330例,分离14238株流感病毒,分离阳性率为11.54%。职业分布以托幼儿童及散居儿童为主。年龄分布以0~4岁组所占比例最大。结论江苏省流感每年有两个高峰期,分别是1~3月和7~10月。2010-2012年,B型和季节性H3N2是主要流行亚型。2013-2014年,甲型H1N1和季节性H3N2成为主要流行株亚型。Objective To analyze the epidemiology Characteristic of influenza by cases from 13 sentinel sites for hospital-based influenza surveillance in Jiangsu province during 2010 -2014 and to explore influenza prevention and control. Methods Accdrding to the requirements by ＂National Influenza （ swine flu） Monitoring Plan＂, influenza-like cases （ILI） from the sentinel hospitals were collected＇. The pharyngeal swab specimen were collected for influenza virus RNA de- tection anti virus isolation. Clinical Cases were entered into the national influenza network monitoring system. Excel 2007 and PASW（Predictive Analytics Software） 18.0 were used for data analysis. Results Total 123 330 ILI cases were reported in five years： 14 238 influenza virus strain were isolated with a positive rate of 11.54%. Kindergarten and scattered children was the dominant group in all occupations. O- age group contributed the largest population by age distribution. Conclusions There are two epidemic peaks of influenza each year in Jiangsu province, from January to March and July to October, respectively. In the years of 2010 to 2012, the epidemic flu strains were seasonal A/H3N2 and type B. The main epidemic flu strain switched to seasonal A/H3N2 and A/H1N1 （09pdm） between 2013 and 2014.
