摘　　要：[目的]了解上海浦东地区流感病原学特征,为流感防治提供科学依据。[方法]选择浦东2个流感监测点医院,采集类流感病人呼吸道咽拭子,利用病原学、血清学结合流行病学资料进行分析。[结果]2007年采集类流感病人呼吸道咽拭子标本210份,分离到98株流感病毒,总检出率为46.7%。未分离到A(H1N1)亚型。分离到A(H3N2)亚型、B/Y亚型、B/V亚型62、32、4株,分别占总检出数的63.3%、32.6%、4.1%。呈现1—3月和7—9月2个活动高峰。[结论]2007年浦东地区流感病毒优势株亚型不断发生变化,从年初的A(H3N2)优势株亚型逐渐过渡为A(H3N2)亚型与乙型共存,到年末则优势株亚型全部为乙型流感(B/Y,B/V)。流感发病人群在各年龄段均有分布并且与性别无明显相关。[ Objective] To find out the etiological characteristics of influenza in Pudong area to provide scientific supports for influenza prevention in this area. [ Methods ] Throat swab specimens were collected from two influenza inspection sites in Pudong. Influenza virus was analyzed using etiological and serological methods. [ Resuits] A total number of 210 samples were collected in 2007, with 98 strains identified as influenza virus （ 46.7 % ）. Among these strains, no strain was A （ H1 N1 ） subtype, 62 strains were A （ H3 N2 ） subtype （63.3 % ）, 32 strains were B/Y subtype （ 32.6% ） and 4 strains were B/V subtype（ 4.1% ）. Two epidemic peaks （ January to March and July to September） were observed. [ Conclusion] Main influenza subtypes changed continuously from A （ H3 N2 ） at the beginning of 2007 to coexistence of A （ H3 N2 ） and B then B subtype at the end of 2007. No A （ H1 N1 ） was observed during 2007. Research showed that the influenza infection was independent of age and gender.
