摘　　要：目的：探讨2000-2004年武汉地区流感流行规律。方法：选择监测点进行流感流行病学和实验室监测，开展正常人群流感抗体水平调查。结果：门诊流感样病例数的百分比在12月、1月和8月有明显升高；从2047份标本中共分离到流感病毒244株，分离率为11．92％，月分离率同样在12月、1月和8月有明显升高；抗体水平调查显示人群中对类疫苗株的抗体水平分别为甲1型1．33％，甲3型40．67％，乙型Victoria系为12．67％，乙型Yamagata系为5．33％，而对甲3型地方株的抗体水平则高达72．67％。结论：通过观察门诊流感样病例数的百分比变化，可以大体推测流感活动强弱；人群抗体水平调查较准确地反映了流感病毒的流行状况。Objective： To probe into the regular epidemic pattern of influenza in area of Wuhan from 2000 - 2004. Methods： E.pidemiology and laboratory surveillance of influnzahave had been devdoped in selected surveillance site, antibody level investigation of influenza among normal people had been launched as well. Results： Percentage of visits for Influenza- Like Illness （ILI） increased evidently in December, January and August. A total of 244 virus strains （11.92%） had been isolated from 2047 specimeats. The monghly percentage of virus strains isolated also peaked in December, January and August. Investigation indicated that the antibody level to vaecinestrainwerel.33% （H1）, 40.67% （H3）, 12,67% （B/Victoria）and 5.33% （B/Yanmgata）respeetivdy, and the antibody level to H3 local strain was 72.67%. Conclusion： Influenza epidemic peaks of summertime and wintertime can be observed in area of Wuhan every year. Activity of influenza can generally be detected through the percentage variation of visits for ILI. The result of antibody level investigation reflect the epidemic status of influeza virus mostly.
