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 surveillance results of influenza (influenza) in Urumqi from 2009 to 2010. Methods The proportion of cases of influenza-like illness (ILI) reported by surveillance clinics in 2009-2010 sentinel surveillance hospitals was collected. Influenza etiology was detected in samples of flu-like illness, and the results were analyzed and analyzed. Data for 2006-2008 are compared. Results The surveillance of influenza-like cases showed that the ILI% of 35 weeks (the percentage of flu-like cases accounted for the total number of outpatient visits) began to rise in waves. From 41 weeks (after the 11th holiday) to 44th week, ILI% Peak (17.01%), is the highest level in recent years. After 45 weeks, ILI% showed a rapid and continuous downward trend, dropping to 4.35% of 50 weeks. The etiological tests showed that the sentinel hospital collected 1 915 copies of the positive and 511 positive influenza viruses with a positive rate of 26.68%, of which 396 were positive for type A H1N1, accounting for 77.50%, 43 were H3N2-positive, 8.41% were H1N1 Positive 18, accounting for 3.52%, B positive 54, accounting for 10.57%. Conclusion In the monitoring year, the outbreak of influenza A (H1N1) occurred in Urumqi. The peak appeared at 44 weeks, 8 weeks earlier than in previous years. After 2010, influenza A (B) prevailed.
