摘要
目的对2009-2010年度乌鲁木齐市流行性感冒(流感)监测结果进行分析。方法统计2009-2010年度流感监测哨点医院监测诊室报告的流感样病例(influenza-like illness,ILI)就诊比例,采集流感样病例标本进行流感病原学检测,对监测结果进行整理、分析,并与2006-2008年度数据进行比较。结果流感样病例监测显示,35周ILI%(流感样病例占门诊就诊病例总数的百分比)开始呈波浪式上升,41周(十一长假后)至第44周ILI%开始急骤上升,44周达高峰(17.01%),是近几年最高水平。45周开始ILI%又呈快速连续回落趋势,下降到50周的4.35%。病原学检测显示,哨点医院采集的标1 915份本中,流感病毒阳性511份,阳性率26.68%,其中甲型H1N1阳性396份,占77.50%,H3N2阳性43份,8.41占%,H1N1阳性18份,占3.52%,B型阳性54份,占10.57%。结论在本监测年度乌鲁木齐市发生甲型H1N1暴发流行,高峰出现在44周,较往年提前了8周,进入2010年后则以B型流感病毒流行为主为主。
Objective To analyze the monitoring resuh of influenza in Urumqi from 2009 to 2010. Method Cal-culate the influenza - like illness （ILI） cases reported by sentinel hospitals from 2009 to 2010, collect ILI samples to do etiological detection ; analyze the surveillance data, and compare with the data of that from 2006 to 2008. Results The result of ILI surveillance indicated that ILI% （ the percentage of ILI cases to the total number of outpatients） began to increase in wave mode from the 35th week, increase rapidly from the 41st week （ after the National Day） to the 44th week, and reached the peak in the 44th week （ 17.01%, the high- est in the recent years） It presented a rapid consecutive decending trend from the 45th week, until to 4. 35% at the 50th week. The etiological detection result showed that 511 cases were influenza virus positive among the 1 915 samples, and the positive rate was 26. 68%. Among them, 396 （77.50%） were A - type H1N1 positive, 43 （8.41%） were H3N2 positive, 18 （3.52%） were H1N1 positive, and 54 （10. 57） were B-type positive. Conclusions There was A-type HIN1 epidemics in Urumqi in this year, and the peak oc-curred in the 44th week, 8 weeks early than that of previous years. The epidemics was mainly influenza B vi-rus after 2010.
