摘要
[目的]了解武汉市2006～2007年度流感流行状况,为流感防控提供依据。[方法]通过流行病学、病原学和血清学监测,对武汉市近年的流感流行情况进行分析。[结果]在1772550例门诊病例中监测到流感样病例185971例,ILI就诊比例为10.5%;共采集流感样病例咽拭标本933份,分离到不同型别的流感病毒294株,其中H1N1型占37.8%,H3N2型占25.5%,B型Victoria系18.0%,B型Yamagata系19.0%;人群中H3N2的血清抗体水平最高;武汉市流感流行状况呈双峰型,流感样病例就诊比例变化与病毒分离率相一致,两年来流感流行优势株由H1N1亚型变为H3N2亚型。[结论]武汉市仍应加强对各型流感病毒的监测,以预防、控制流感的流行。
[ Objective ] To understand the regular epidemic pattern of influenza in Wuhan from 2006-2007, so as to provide basis for preventing influenza. [ Methods] Epidemiology, etiology and laboratory surveillance of ifluenza had been conducted to analyze the epidemic status of influenza in Wuhan in recent years. [ Results] Among 1772550 outpatients, 185971 outpatients were Like Illness （ILI） influenza patients accounted for10.5%. A total of 294 virus strains had been isolated from 933 specimens selected from the ILI influenza patients. The subtypes arrangement were H1N1 （37.8%）, H3N2 （25.5%）, B/Victoria （18.0%） and B/Yamagata （19.0%）, respectively. The sernm antibody level of H3N2 in population was the ilighest among all the other subtypes. The influenza epidemic status in Wuhan showed to be bimodal pattern, and the proportion of visiting for ILl was in line with the viral isolation rate. The predominant subtype turned from H1N1 to H3N2 during the recent two years. [Conclusion] It is necessary to enhance the influenza surveillance in Wuhan area to prevent and control influenza.
