目的分析武城县2005~2012年乙型肝炎上升原因,为病毒性肝炎防治工作提供科学依据。方法通过中国疾病预防控制系统收集数据,采用描述性流行病学方法对武城县2005~2012年乙型肝炎监测资料进行分析。结果 2005~2012年乙肝发病957例,总发病率为31.22/10万,8年时间乙肝发病率上升了38.12/10万,上升幅度为5.69倍。不同年份发病率的差异有统计学意义(P<0.01)。男性发病659例、女性298例,男女性别比为1∶0.45。结论疫情网络直报系统监测灵敏度提高、社会经济需求的人口流动性增加、感染人群的年龄自然增长和消亡、陈旧感染病人的新发现等因素成为我县乙肝发病上升的重要因素。
