[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 epidemic situation of influenza in Wuhan City from 2006 to 2007 and provide basis for prevention and control of influenza. [Methods] The prevalence of influenza in Wuhan in recent years was analyzed through epidemiological, etiological and serological surveillance. [Results] A total of 185971 influenza-like cases were detected in 1772550 outpatient cases and the ILI treatment rate was 10.5%. A total of 933 swallowing samples of influenza-like cases were collected and 294 strains of influenza viruses were isolated, of which H1N1 type accounted for 37.8%, H3N2 type accounted for 25.5%, type B Victoria 18.0%, type B Yamagata 19.0%; the highest level of serum antibodies to H3N2 among the population; the prevalence of influenza in Wuhan was bimodal, the proportion of influenza-like cases was changed with virus The rate of separation was consistent. Influenza prevalence strains changed from H1N1 subtype to H3N2 subtype in the past two years. [Conclusion] The surveillance of all kinds of influenza viruses should be strengthened in Wuhan so as to prevent and control the epidemic of influenza.
