2008～2009年烟台市流感病原学监测结果分析

Analysis of the results of monitoring of flu virus etiology in 2008 and 2009

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)。

This study sought to contrast and analyze the results of monitoring of flu virus etiology in 2008 and 2009 in YanTai.Nine hundred and thirty specimens were collected from patients with influenza-like illness （ILI） at two sentinel hospitals for the national monitoring of ILI （excluding influenza H1N1）.One hundred and thirty strains of the influenza virus were isolated from specimens at a rate of 13.98%.In a total of 426 specimens from 2008 to 2009,62 strains of the influenza virus were isolated at a rate of 14.55%.In a total of 504 specimens from 2009,68 strains of the influenza virus were isolated at a rate of 13.49%.In 2008-2009,the H1N1 subtype was the dominant strain,accounting for 95.16% of strains detected （59 strains）;in 2009,the H3N2 subtype was the dominant strain,accounting for 76.47% of strains detected（52 strains）.
