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3 287例可疑病例的咽拭子、鼻拭子进行检测.结果 3 287例可疑病例中检测出甲型流感患者1 039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H1N1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.

abstractsObjective To detect and analyze epidemiology characteristic of influenza A/H1N1.Methods Pharynx and nose swabs of 3 287 doubtful 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 H1N1 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 ＜0.01).Conclusions Epidemic trend of influenza A/H1N1 suddenly increases and slowly decreases,then obviously weakens when it reaches peak in October 2009.
