目的分析西藏自治区2018—2023年乙型肝炎的流行病学特征及逐年变化趋势,并进一步分析地区、年龄段患病特征。以期为西藏自治区开展乙型肝炎的预防和控制提供借鉴。方法收集2018—2023年西藏自治区疾病预防控制中心医学检验科乙型肝炎新发病例信息,进行统计描述分析,主要观察指标为发病例数、发病率,并分析逐年发病变化趋势。结果2018—2023年期间西藏自治区共报告23287例乙型肝炎患者,其中急性乙肝1611例(7.86%)、慢性乙肝15249例(72.82%)、未分类乙型肝炎3474例(16.35%)。20~40岁是乙型肝炎的高发年龄段。昌都和那曲两个地区乙型肝炎患病率最高,分别为177.35/10万和106.53/10万。结论西藏自治区应进一步加强乙型肝炎监测质量控制,同时应充分发挥传染病预防的作用,以降低此类传染病的流行率。
