目的检测7个月疑是甲型H1N1流感病毒特异片断,分析本地区H1N1流感病毒的流行病学特点。方法采用实时荧光定量(Real Time RT-PCR)法,对2039例可疑病例的咽拭子、鼻拭子进行检测。结果检测出甲流患者791例,检出率为38.79%(791/2039);甲流H1N1157例,检出率为7.7%(157/2039),各月检出率均有不同。结论本地区甲型流感是在8月开始多发,以普通甲流感染为主,甲型H1N1流感混在其中,本地区的传播高峰是在10月。 Objective To detect the 7-month-old suspected influenza A (H1N1) virus specific fragment and analyze the epidemiological characteristics of H1N1 influenza virus in this area. Methods Real-time quantitative real-time RT-PCR was used to detect throat swab and nasal swab in 2039 suspected cases. Results A total of 791 cases of influenza A were detected, the detection rate was 38.79% (791/2039). The detection rate of H1N1 influenza A virus was 7.7% (157/2039). The detection rates were different in each month. Conclusion Influenza A (H1N1) influenza in the region started to occur frequently in August. Influenza A (H1N1) was the main source of influenza A (H1N1). The highest peak in the region was in October.
