Several European countries report a decreasing prevalence of antibodies to hepatitis A virus (anti-HAV). This trend is most pronounced in the youngest age groups. In 1979, however, 58% of young Austrians aged 20 to 30 years were shown to possess anti-HAV. Here we describe the current epidemiological situation in western Austria. Prevalence of anti-HAV has decreased to 7% in those 18 to 30 years old. This percentage rises to 20% (31 to 40 years of age) and 57% (41 to 50 years of age) and is highest in those older than 50 years (87%). Of 180 cases of clinical hepatitis A occurring from 1985 to 1992 45% were imported by travel to HAV-endemic areas. Seventy-one percent of the cases in children (59/83) occurred in foreign workers' families and were also predominantly acquired abroad. A change in prevention policy should be considered in this respect, as vaccination is available now.
几个欧洲国家报告甲型肝炎病毒抗体（抗-HAV）的流行率在下降。这一趋势在最年轻的年龄组中最为明显。然而，1979年，20至30岁的奥地利年轻人中有58%被证明拥有抗-HAV。在此，我们描述奥地利西部目前的流行病学情况。18至30岁人群中抗-HAV的流行率已降至7%。这一比例在31至40岁人群中升至20%，在41至50岁人群中升至57%，在50岁以上人群中最高（87%）。在1985年至1992年发生的180例临床甲型肝炎病例中，45%是因前往甲型肝炎流行地区旅行而输入的。儿童病例（59/83）中有71%发生在外国工人家庭，也主要是在国外感染的。鉴于现在有疫苗可用，在这方面应考虑改变预防政策。
