摘　　要：目的检测分析甲型H1N1流感病毒在本地区1年内的流行病学特点。方法采用实时荧光定量法对2009年6月至2010年5月就诊的3287例可疑病例的咽拭子、鼻拭子进行检测。结果3287例可疑病例中检测出甲型流感患者1039例，检出率为31．61％，其中甲型H1N1流感病毒179例，总检出率为5．45%。X2。线性趋势检验结果显示2009年10月甲型HINl流感病毒检出率（15．36％）远高于其他月份（P〈0．01）。结论2009年6月至2010年5月甲型H1N1流感的传播呈现骤然上升稳步下降的趋势，在2009年10月达高峰后呈明显减弱趋势。Objective To detect and analyze epidemiology characteristic of influenza A/H1N1. Methods Pharynx and nose swabs of 3 287 dotlbtful cases from June 2009 to May 2010 were detected with real time PCR. Results Influenza A patients were 1 039 in 3 287, detection rate was 31.61%. Patients who infected HIN1 virus were 179 in 3 287, detection rate was 5.45%. Result of linear chisquare test showed that detection rate during October 2009 was significantly higher than that in other months（ P d0.01）. Conclusions Epidemic trend of influenza A/H1N1 suddenly increases and slowly decreases, then obviously weakens when it reaches peak in October 2009.
