目的:分析内蒙古自治区2010年4月-2011年3月流感监测结果,为内蒙古流感防控工作提供科学依据。方法:收集和分析内蒙古自治区2010年度流感样病例(ILI)监测数据。采集ILI咽拭子标本进行流感病毒核酸检测并分析病原学监测资料。结果:2010年度,内蒙古自治区ILI%是1.64%,流感病毒核酸检测阳性率为11.06%。东部、中部和西部的夏秋季、中部和西部的冬春季检出率最高的流感病毒分别是A(H1N1)、B型和A(H3N2)。结论:内蒙古地区2010年4月-2011年3月均有流感病毒活动,东部地区主要流行A(H1N1)流感病毒,中部和西部冬春季主要流行A(H3N2)流感病毒。
Objective: To analyze the results of influenza surveillance in Inner Mongolia Autonomous Region from April 2010 to March 2011 and provide a scientific basis for prevention and control of influenza in Inner Mongolia. Methods: Collecting and analyzing 2010 annual surveillance data of flu-like illness (ILI) in Inner Mongolia Autonomous Region. ILI throat swab specimens were collected for influenza virus nucleic acid detection and analysis of etiological monitoring data. Results: In 2010, the ILI% in Inner Mongolia Autonomous Region was 1.64%, and the positive rate of influenza virus nucleic acid was 11.06%. Influenza viruses with the highest prevalence in winter and spring in central, western and central China were A (H1N1), B (type A) and A (H3N2), respectively, in summer, autumn in eastern, central and western China. CONCLUSIONS: Inner Mongolia had influenza virus activities from April 2010 to March 2011, with influenza A (H1N1) virus in the eastern part of China and influenza A (H3N2) virus in the central and western China in winter and spring.
