摘　　要：目的了解在2009甲型H1N1流感流行早期输入性疑似患者（含确诊病例）的流行病学特征，为早期识别、防控甲型H1N1流感提供依据。方法：回顾分析广东省中医院急诊科从各口岸检疫接收的输入性甲型H1N1流感疑似患者的相关信息，用Excel建妒病例的个案信息库，用SPSS软件进行统计分析。结果2009年5至8月，广冻省中医院急诊科共接收146例输入性甲型H1N1流感疑似患者，男性109名（74．7％），平均年龄28．47±11．19岁，就诊时平均体温38．12±0．70℃。其中甲型H1NI流感确诊病例33例（22．6％），甲型H1N1病毒核酸阳性病人的咳嗽症状发生率明显高于阴性病人（P〈0.01），其它临床症状与体征两组比较无差异。甲型H1N1病毒核酸阳性病人的白细胞平均数、淋巴细胞平均数明显低于阴性病人（P〈0．05），无重症或死亡病例。结论：2009年甲型H1N1流感流行早期本院接收的输入性疑似病例以青年男性为多，确诊病例临床症状与其它流感相似，白细胞及淋巴细胞的降低为本病诊断提供参考，明确诊断尚需病原学检测。Objective Understanding the epidemiologic feature of suspected patients In the H1N1 pandemic influenza 2009,providing evidence for early identification and precautionary measures of H1N1 pandemic influenza.Method Emergency Department of Guangdoug Province Hospital Of Chinese Medicine retrospect and analyze the relevant symptoms of the suspected patients received from various quarantine counters,Using Excel for establishing a medical database and SPSS for statistical analysis.Results Statistics show that in the period between May and August,2009,the Emergency Department of Guangdong Provincial Hospital of Chinese Medicine had received 146 imported HINI pandemic influenza suspected cases,109 of which were male patients （74.7%）.The average age of all patients was 28.47 ±11.19,mean body temperature was 38.12 ± 0.70℃ when they were examined.Among them there were 33 （22.6%） confirmed cases,test positive patients coughed obviously more frequently than test negative patients （P 〈 0.01）.Meanwhile,other clinical symptoms and physical signs displayed no difference in the separate groups.H1N1 pandemic influenza virus DNA test positive cases＇ average number of leucocytes and lymphocytes appeared lower evidently than test negative cases （P 〈0.05）.No severe cases and no deaths had appeared.Conclusion The number of Young men takes the great proportion of that of suspected patient in initial stage of H 1N 1 pandemic influenza; the symptom is similar to other flu.The decreased number leucocytes and lymphocytes provide clinical reference for its diagnosis.Nevertheless,to make a definite diagnosis requires further laboratory etiology examination.
