摘　　要：[目的]了解海南省流感流行情况,及时发现变异毒株,为流感预防和控制提供科学依据。[方法]收集2004～2006年海南省流感哨点医院监测资料,流感样病例病毒分离与鉴定结果以及暴发疫情调查资料,采用描述流行病学的方法进行分析。[结果]2004～2006年海南省哨点医院门诊病例总数为884039例,监测到流感病例数11760例,占门诊病例总数的1.33%,发病高峰期为4月和5月;发生暴发疫情6起,共发病516人,罹患率5.07%;采集流感病样例咽拭子标本1712份,分离出流感病毒234株,其中H1N1型46株,H3N2型125株,B型63株。分离率13.67%,病毒分离率的高低与流感流行季节高峰一致;引起暴发的流感病毒以H3N2型为主。[结论]海南省一年四季均有流感病例发生,发病高峰在春末夏初季节,各年龄组均有病例发生,但5～14岁年龄段流感病毒分离率最高,学校是发生流感暴发疫情的高危场所。流行毒株为H1N1型、H3N2型和B型交替发生,但以H3N2型为优势毒株。没有发现人感染高致病性禽流感病毒(H5N1)。[Objective] To understand influenza epidemic and find out virus variance in time. so as to provide scientific evidence for prcvcnting and controlling in Hainan. [Methods] By collecting the surveillance information isolation and identification of vires among the influenza-like case and the investigation of the outbreak in Hainan sentinel hospitals during 2004- 2006, and analyzing by the descriptive epidemiology study. [ Results] From 2004 to 2006. the percentage of influenza-like illness （11 760 eases） in out-patient department （884 039 cases） was 1.3397. The peak incidence months were April and May. Among the total 516 incidence cases, there were 5 outbreaks, and the attack rate was 5.07%. Throat swab specimens of 1712 patients were collected in influenza-like illness, ineluding 46 strains H1N1 virus. 125 strains H3N2 virus and 63 strains type B, which is the same as the peak season of influenza epidemic. Most outbreaks were caused by H3N2 virus. [Conclusion] Influenza appears all through the year and mostly in the late spring and early summer in Hainan, and itffeets different especially in group of 5-14 year-old. Most outbreaks happened in schools. The epidemic influenza virus stratus were H1N1, H3N2 and type B, of which H3N2 caused more eases. No influenza vires variance and lethal avian infuenza virus emerged.
