2009～2010年山西省流行性感冒监测资料分析

Analysis on Influenza Surveillance in Shanxi Province,2009-2010

[目的]掌握山西省流行性感冒(流感)的流行动态和病原学特征,为山西省流感防控提供科学依据。[方法]对2009年第20周至2010年第13周山西省流感监测哨点医院报告的流感样病例就诊比(ILI%)和流感样病例标本病原学检测资料进行。[结果]2009年第20周至2010年第13周,流感样病例就诊比(ILI%)为4.33%,高峰在第45周(13.89%);累计检测流感样病例标本5 656份,流感病毒核酸阳性的2 022份,阳性率为35.75%,其中甲型H1N1流感核酸阳性的占54.90%;季节性流感A(H3N2)亚型核酸阳性的占22.35%,季节性流感B型核酸阳性的占22.01%,季节性流感混合型核酸阳性的占0.49%,季节性流感A(H1N1)亚型核酸阳性的3份,占0.15%;季节性A型未分型2份,占0.10%。[结论]2009年第20周至2010年第13周山西省流感监测哨点医院报告的流感样病例就诊比与病原学监测结果基本一致。

[Objective]To explore the influenza epidemic situation and its strains of the virus in Shanxi province,2009-2010,so as to provide the scientific basis for its prevention and control.[Methods]The surveillance data on influenza-like illness（ILI） and influenza virus,2009-2010 were collected for analysis from all sentinel hospitals in Shanxi province.[Results]ILI percentage（ILI%） was 4.33% 2009-2010,and the peak of ILI% was 13.89% during week 45 in 2009.Of 5 656 specimens tested for influenza,the positive rate by influenza type and subtype was 35.75%.including influenza A H1N1（54.90%）,influenza A（H3N2）（22.35%）,type B（22.01%）,the mixed（0.49%）,influenza A（H1N1）（0.15%） and untyped（0.10%）.[Conclusion]The influenza-like illness proportion reported by influenza surveillance sentinel hospitals in Shanxi province in the 20th week,2009 and the 13th week,2010 are basically the same with pathogenic surveillance results.
