EPI实施后中国成人中乙肝发病率仍较高 近几年乙肝感染率虽然在小年龄组有较大幅度的下降，但全人群乙肝发病持续上升，其中固然有诊断和报告的原因，但从对全国营养血样检测分析结果来看，全人群乙肝表面抗原携带率下降并不明显。 认真贯彻落实?疫苗流通和预防接种管理条例? 依法实施国家免疫规划 卫生部政策法规司卫生政务通报第15期，2005、6、16 * hhhhhhhhhhh 卫生部加强乙肝防治工作 卫生部将乙肝作为继艾滋病、结核病、血吸虫病后第四个重点控制的传染病。 认真贯彻落实?疫苗流通和预防接种管理条例? 依法实施国家免疫规划 卫生部政策法规司卫生政务通报第15期，2005、6、16 * hhhhhhhhhhh 卫生部加强乙肝防治工作 卫生部十年防治乙肝的总体目标是： 采取免疫预防为主、防治兼顾的综合措施，优先保护新生儿和重点人群，有效遏制乙肝的高流行状态，至2015年使我国人群乙肝发病率和乙肝表面抗原携带率有显著下降。 卫生部十年防治的3个具体目标： 一是10岁以下儿童乙肝表面抗原携带率降至1%以下； 二是全人群乙肝表面抗原携带率降至7%以下； 三是全人群乙肝表面抗原携带率已低于7%的省份，应进一步降低1～1.5个百分点。 认真贯彻落实?疫苗流通和预防接种管理条例? 依法实施国家免疫规划 卫生部政策法规司卫生政务通报第15期，2005、6、16 * hhhhhhhhhhh [SLIDE 1] Title Slide This slide set presents an overview of the clinical and epidemiologic features for viral hepatitis A, B, C, D, and E and prevention measures for these infections.

In high prevalence areas, the lifetime risk of HBV infection is 60%, and most infections are acquired at birth or during
