【摘要】：目的分析许昌市流行性感冒监测结果,了解流感流行特征及毒株的型别分布,为流感防控提供科学依据。方法通过中国流感监测信息系统收集许昌市流感及流感样病例(ILI)监测资料,对其流行病学、病原学进行分析。采用狗肾传代细胞(MDCD)对流感病毒进行培养,对分离到的毒株采用血凝抑制实验进行型别和亚型鉴定。结果许昌市2011年-2013年ILI全年均有病例发生,ILI%呈上升趋势,就诊高峰出现在12月份至次年3月份;人群分布主要集中在≤15岁年龄组,占66.81%(24 915/37 291);在1 219份ILI标本中核酸阳性检出率为11.48%。77份核酸阳性标本中分离到流感病毒38株,病毒分离阳性率为49.35%。结论许昌市流感病毒活动高峰在冬季和春季,流行有明显的季节性,甲3亚型和B型病毒为主要流行株,须加强监测与防控。
[Abstract]:Objective to analyze the surveillance results of influenza in Xuchang city and to understand the epidemic characteristics and the type distribution of influenza strains so as to provide scientific basis for influenza prevention and control. Methods the surveillance data of influenza and influenza-like cases in Xuchang City were collected by China Influenza Surveillance Information system, and their epidemiology and etiology were analyzed. The influenza virus was cultured by Dogs kidney passage cell line MDCD, and the isolated strains were identified by hemagglutination inhibition test. Results the incidence of ILI cases in Xuchang City from 2011 to 2013 showed an increasing trend, and the peak of visits was from December to March of the following year, and the population distribution was mainly in the age group of 鈮，
