目的了解江苏省流感的流行病学特征，评价流感监测工作方法并为流感防治提供科学依据。方法对2004年1月～2007年5月江苏省监测哨点医院的流感样病例（Influenza Like Illness，ILI）监测资料、病原学监测资料以及全省暴发疫情调查处置...目的了解江苏省流感的流行病学特征，评价流感监测工作方法并为流感防治提供科学依据。方法对2004年1月～2007年5月江苏省监测哨点医院的流感样病例（Influenza Like Illness，ILI）监测资料、病原学监测资料以及全省暴发疫情调查处置信息进行分析。结果2004～2007年流感监测显示，江苏省可能存在冬春季、夏季2个流感流行高峰。ILI的年龄构成特征以低年龄组为主。流感毒株类型构成改变多在9月前后。流感暴发疫情主要发生在中小学校。结论流感监测工作应重点关注新型流感毒株的出现，同时加强学校暴发监测。目前流感监测存在不足，ILI监测指标流感流行效果有待评价；敏感的新型综合性监测方法与手段有待探索。展开更多
