目的对北京市平谷区2007—2012水痘疫情统计分析,掌握近几年水痘流行特征,为今后制定调整水痘防治措施提供依据。方法运用描述流行病学方法对该区进行2007—2012年水痘疫情报告信息资料进行统计分析。结果全区共报告水痘2 688例,临床诊断病例2 687例,占99.96%;其中暴发疫情病例92例,占3.42%。发病人群以学龄儿童为主,占80.25%。男女性别比为1.15∶1。农村发病高于城区,为1.24∶1。全年均可发病,发病高峰月主要是上年12月到次年1月和当年5月到7月两个高峰。发病人群中接种疫苗和不接种疫苗人群差异有统计学意义(P<0.01)。结论平谷区水痘发病主要在冬季和夏季,儿童为水痘的高发人群,在这两个季节应加强学龄儿童和散居儿童特别是农村学校、托幼园所水痘疫情的监测,加强重点人群宣传教育,加强水痘疫苗应急接种的及时性,及时采取隔离病例等控制措施,以减少暴发疫情的发生,进一步降低水痘发病率。
