Between 1988 and 1996, the Swiss Federal Office of Public Health received 200 to 500 reports of acute hepatitis B each year, mostly affecting adults aged 15 to 40 (80% of all reports). Considering the problem of underreporting and the fact that most infections are asymptomatic or remain undiagnosed because of atypical symptoms, the yearly incidence of new infections is estimated to be between 2000 and 3000. About 20,000 persons are chronically infected (0.3% of the population) and acute and chronic complications of hepatitis B (fulminant hepatitis, cirrhosis, hepatocarcinoma) lead to an estimated 40 to 80 deaths each year.
1988年至1996年间，瑞士联邦公共卫生局每年收到200至500例急性乙型肝炎报告，主要影响15至40岁的成年人（占所有报告的80%）。考虑到报告不全的问题以及大多数感染无症状或因症状不典型而未被诊断的情况，新感染的年发病率估计在2000至3000例之间。约20000人慢性感染（占人口的0.3%），乙型肝炎的急性和慢性并发症（暴发性肝炎、肝硬化、肝癌）估计每年导致40至80人死亡。
