2010年赤峰市流感病原学监测结果分析

Analysis of Monitoring Result of Influenza Pathogen in Chifeng in 2010

目的通过对流感样病例监测,了解赤峰市流感流行特征,掌握流行规律,为临床诊断和预防控制流感提供依据。方法采集哨点医院流感样病例的咽拭子标本,采用RT-PCR方法检测流感病毒核酸并分型鉴定。结果 2010年共检测流感样品737份,检出流感阳性样本104份,阳性率14.11%,其中B型21份,占20.19%;季节性A(H1N1)76份,占73.08%;季节性A(H3N2)7份,占6.73%。结论 2010年主要以季节性H1N1为主,除未检出甲型H1N1外,主要流行亚型与北方地区基本一致。应进一步加强检测能力,及时发现病毒的变异情况,做好赤峰市流感全年动态监测工作。

Objective To analyze the epidemic characteristics of influenza in Chifeng, master the epidemic regularity and provide scientific basis for diagnosis, further prevention and control of influenza in this area. Methods Throat swab specimens from flu patients from sentinel hospitals were collected for influenza virus nucleic acid detection and type identification with RT-PCR method. Results 104 influenza virus positive samples were detected from 737 samples in total. In the positive samples, the percentage of B type （21 samples）, seasonal A HIN1 type （76 samples） and seasonal A H3N2 type （7 samples） were 20.19%, 73.08% and 6.73% respectively. Conclusion Seasonal H1NI was the main influenza virus in Chifeng in 2010, which was similar with northern China except A HIN1 influenza virus was not detected.
