【摘要】：目的了解2010-2012年南昌市流感流行趋势及其病毒株变化特点,为本地区防控流感提供科学依据。方法通过中国流感监测信息系统统计南昌市3家流感监测哨点医院流感样病例数据及网络实验室对哨点医院采集标本的核酸检测结果,分别从年度ILI年龄构成、ILI就诊百分比变化曲线、流感病例报告数、流感毒株型别季节分布和病毒分离率等指标来进行分析比较。结果南昌市哨点医院共监测ILI病例2 415 240例,ILI就诊百分比为5.48,共报告流感病例数910例;网络实验室共检测哨点医院采集的标本1 347份,阳性率为16.11%,其中B型占40.55%,季节性H3型占44.24%,甲型H1N1占15.21%。结论 2010-2012三个流感监测年度南昌市流感一般在冬、春、夏季流行,病毒株以B型、季节H3型和甲型H1N1型相互交替流行,在不同的监测年度流感优势毒株型别存在变化,应进一步加强流感监测工作。
[Abstract]:Objective to understand the epidemic trend of influenza in Nanchang city from 2010 to 2012 and to provide scientific basis for the prevention and control of influenza in this area. Methods Influenza case data of three influenza surveillance sentinel hospitals in Nanchang City were analyzed by China Influenza Surveillance Information system and the results of nucleic acid detection in sentinel hospitals collected by network laboratory. The percentage change curve of annual ILI age, the number of influenza cases reported, the seasonal distribution of influenza strains and the virus isolation rate were analyzed and compared. Results the percentage of ILI cases monitored by sentinel hospital in Nanchang City was 5.48, 910 influenza cases were reported, and 1 347 samples were collected from sentinel hospital in network laboratory. The positive rate was 16.11, of which 40.55 were type B, 44.24 were seasonal H3 and 15.21 were type A H1N1. Conclusion the three influenza surveillance years in Nanchang City from 2010 to 2012 were generally prevalent in winter, spring and summer. The strains of influenza B, H3 and H1N1 were alternately prevalent, and there were changes in the types of dominant strains of influenza in different surveillance years. Influenza surveillance should be further strengthened.
