摘　　要：目的了解病毒性肝炎的发病和分布情况，掌握流行规律，为进一步制定预防控制措施提供科学依据。方法采用描述流行病学方法，对传染病统计年报表、疫情汇编资料及疫情专题调查报告进行统计分析。结果近10年来病毒性肝炎的发病率波动在53．39／10万-16．08／10万，平均发病率为31．69／10万。甲肝发病率逐年下降，乙肝发病率也呈下降趋势，但其在肝炎病例中的构成比逐年上升。发病主要集中在每年的3—6月份，发病数占全部病例数的49．03％；各个乡镇、街道均有病例发生；发病年龄以20一49岁的青壮年为主，男性多于女性；职业分布以农民为主（33．68％），其次为学生（21．89％）、工人（14．63％）。结论接种疫苗是预防控制病毒性肝炎发病的主要措施，在青壮年、成人中开展乙肝疫苗的普遍接种是控制乙肝发病的重要措施。Objective To obtain a better understanding of the distribution and epidemiological characteristics of virus hepatitis, which could provide scientific evidence for further preventive measures.
