目的了解泉州市2009年流感活动情况及其型别特征。结论通过流行病学和病原学监测,对泉州市流感流行情况进行分析。结果 2009年全市流感样病例占就诊人数的0.26%～2.34%;全年采集监测标本1392份,经RT-PCR法检测样本阳性率为22.34%;经MDCK细胞分离流感毒株134株,其中季节性H3N2和HINl型各占60.45%和11.19%,甲型H1N1流感占21.64%,B型占6.70%。结论 2009年泉州市流感春夏季以季节性H3N2亚型流感为优势毒株,秋冬季以甲型H1N1流感为流行株,需加强泉州市流感监测和流感病毒抗原变异研究。
Objective To understand the situation of influenza in 2009 in Quanzhou and its type characteristics. Conclusion Epidemiology and etiology monitoring were used to analyze the prevalence of influenza in Quanzhou. Results In 2009, influenza-like cases accounted for 0.26% ~ 2.34% of the total number of visits in the city. In the whole year, 1392 samples were collected, and the positive rate was 22.34% by RT-PCR. 134 strains of influenza virus were isolated by MDCK cells, Sexual H3N2 and HIN1 accounted for 60.45% and 11.19% respectively, Influenza A H1N1 influenza accounted for 21.64% and B accounted for 6.70%. Conclusion Influenza H3N2 subtype influenza was the predominant strain in spring and summer in Quanzhou. In 2009, Influenza A (H1N1) was the pandemic strain in the autumn and winter. Influenza surveillance and influenza virus antigen variation in Quanzhou should be strengthened.
