惠州市2010年流感病原学监测结果研究[摘要] 目的 分析惠州市2010年流感监测的结果，及时掌握流感流行趋势，为制定流感防控策略提供科学依据。方法 通过中国流感监测网络系统，对流感做流行病学和病原学监测，对本市流感流行情况进行分析，并严密监控本地区的流感疫情暴发情况。结果 2010年累计共报告流感样病例20 734例，占监测诊例数的7.51%(20 734/276 018)；共采集流感样病例咽拭子标本642份，检测到不同型别的流感病毒105例，阳性率为16.36%，其中新甲型H1N1亚型20例，占19.05%，季节性H3N2型32例，占30.48%，A型未分型7例，站6.67%，乙型46例，占43.81%。结论 2010年本区未发生较大规模的暴发流行，但仍应加强对各型流感病毒的监测，以预防和控制流感的流行。目前流感监测工作仍存在一些不足，敏感的新型综合性监测方法与手段有待进一步提高。 [关键词] 流行性感冒病毒； 亚型； 监测； 病原学 [中图分类号] R373.1+3 [文献标识码] A [文章编号] 1005-0515（2011）-05-015-02 Analysis on the results of pathogenic surveillance of influenza in Huizhou in 2010 Xu Zhihua, Liang Lihuan, Liu Xuemei, Fang Qiaoyun, Ju Xiongfei (Huizhou Center for Disease Control and Prevention，Guangdong, 516008，China) [Abstract] Objective To analyze the results of etiological surveillance of influenza in 2010 in Huizhou, so as to capture the epidemic information of influenza in time and to provide scientific evidence for influenza control and prevention effectively. Method Epidemiology，etiology and laboratory surveillance of influenza had been conducted to analyze the epidemic status of influenza in Huizhou. Result A total of 20734 influenza-1ike illness cases were reported in 2010, accounting for 7.51% of the total outpatient cases. 642 specimens were collected from influenza-like patients, from which 105 cases of influenza viruses were detected with the isolation rate of 16.36%. Conclusion There are no large scale outbreaks in 2010 in Huizhou. It is necessary to enhance the influenza surveillance to prevent and control influenza. Given that sentinel hospital-based surveillance system has its weakness and it is necessary to explore more sensitive and synthetical surveillance measures in practice. [Keywords] Influenza virus; Subtype; Surveillance; Etiology 流行性感冒(influenza)简称流感，是一种严重危害人体健康的急性呼吸道传染病[1]。流感病毒的抗原易变异，人群对变异株普通易感，控制难度大，使得迄今为止人类还不能有效控制它[2]。2009年在墨西哥暴发的甲型H1N1流感是由一种新型流感病毒引起的，这种病毒能在短时间内迅速传播至全球，人群普遍易感[3]。我国又被国际上认为是流感的多发地，1957年、1968年和1977年3次世界性流感大流行毒株均首发于我国，且
