目的分析深圳市罗湖区住院病人新型甲型H1N1流感的感染情况,为辖区住院病人的甲流防控工作提供依据。方法采用描述性流行病学研究方法对深圳市罗湖区2009年11月至2010年2月期间深圳市人民医院和罗湖区人民医院的住院病人新型甲型H1N1流感的感染情况进行分析。结果在2009年11月至2010年2月期间共检测了292份疑似甲流的住院病人的咽拭子样本,共检出甲流感染者93例。2009年11月份住院病人感染甲流的人数最多,感染率高达68.18%。30岁以下的住院病人感染甲流的人数占住院病人感染甲流总数的81.7%。男女住院病人甲流的感染率比为1.21:1.结论甲流主要感染30岁以下住院病人,因此,需要加强对该年龄段有流感症状的住院病人的甲流排查和管理。
