【摘要】：目的通过对2010-2016年常州市流感监测的流行病学特征分析,为本地区制定流感的防控策略提供参考依据。方法收集2010-2016年常州市流感监测的哨点医院上报的流感样病例(influenza-like illness,ILI)的资料和病原学检测结果并对其进行描述性的流行病学分析。结果 2010-2016年全市累计报告ILI人数97 400例,流感样病例就诊百分比(consultation rate of influenza like illness,ILI%)为1.85%,各年份ILI%的差异有统计学意义(X~2=16 461.59,P0.001),且ILI%有明显的季节性。ILI例数占据前两位的是5~14岁组和0~4岁组。2010-2016年全市各年份病原学阳性率的差异有统计学意义(χ2=230.34,P0.001);本地区以乙型流感和季节性H3流行为主,同时伴有新甲H1N1的交替流行。流感病原学阳性率与ILI%呈正相关(rs=0.26,P=0.017)。结论本地区冬春季节是乙型流感和新甲H1N1的流行季节,夏季是季节性H3的流行季节,15岁以下人群是高危人群。流行高峰前加强高危人群的疫苗接种是有效的防控手段。
[Abstract]:Objective to analyze the epidemiological characteristics of influenza surveillance in Changzhou City from 2010 to 2016, and to provide a reference for the formulation of influenza prevention and control strategy. Methods the data of influenza-like illnessen ILI cases reported by sentinel hospitals in Changzhou from 2010 to 2016 were collected and the results of etiological detection were analyzed. Results 97,400 cases of ILI were reported in the whole city from 2010 to 2016. The percentage of rate of influenza like consultation was 1.85, the difference of ILI% in each year was statistically significant, and the number of ILI% was obviously seasonal. The top two cases were 5- 14 years old group and 04 year old group. 2010-2016 was the year of the whole city. The difference of sex rate was statistically significant (蠂 2: 230.34, P 0.001). The prevalence of influenza B and seasonal H3 was the main epidemic in this area. At the same time, it is accompanied by the alternate popularity of H1N1. The positive rate of influenza etiology was positively correlated with ILI%. Conclusion the season of winter and spring is the epidemic season of influenza B and H1N1, and the season of H3 in summer is the epidemic season of H3. The population under 15 years old is a high risk population. Strengthening vaccination of high-risk population before epidemic peak is an effective means of prevention and control.
