对烟台市2008和2009年度流感病毒病原学监测结果进行对比分析。两年间2个国家级流感样病例监测哨点医院共采集流感样病例标本(排除甲流)930份,分离流感病毒130株,分离率13.98%。2008～2009年度共检测标本426份,分离流感病毒62株,分离率14.55%;2009年度检测504份,分离流感病毒68株,分离率13.49%。2008～2009年度以甲型H1N1亚型为优势毒株,占95.16%(59株);2009年则以甲型H3N2亚型为流行的优势毒株,占76.47%(52株)。
The comparative analysis of the results of influenza virus etiology monitoring in 2008 and 2009 in Yantai City was conducted. In the past two years, 930 samples of influenza-like illness (excluding A-flow) were collected from 2 national-level influenza-like sentinel surveillance sentinel hospitals, and 130 strains of influenza viruses were isolated with a separation rate of 13.98%. A total of 426 specimens were detected from 2008 to 2009, 62 strains of influenza viruses were isolated with a separation rate of 14.55%. 504 strains were detected in 2009 and 68 strains of influenza viruses were isolated with a separation rate of 13.49%. From 2008 to 2009, the subtype A (H1N1) was the dominant strain, accounting for 95.16% (59 strains). In 2009, the dominant strain was H3N2 (76.47%).
