目的分析陕西省2005-2017年水痘疫情的流行病学特征,为控制水痘暴发和流行提供依据。方法数据来自中国疾病预防控制信息系统中陕西省2005-2017年水痘报告病例及突发公共卫生事件信息,采用描述性流行病学方法进行分析。结果陕西省2005-2017年共报告水痘病例101 370例,死亡1例,年平均发病率为20.77/10万;有明显的季节性,每年6月和12月出现两个发病高峰。病例主要集中在14岁及以下人群,占总发病数的78.63%,2015年14岁及以下人群年均发病率为208.37/10万;同期共报告水痘突发公共卫生事件98起,主要集中在小学。水痘-带状疱疹病毒进化枝2是陕西优势基因型。结论儿童为水痘的高发人群,应加强学校的监测处理措施及民众疫苗接种意识,进而降低水痘发病率。
