In a study of the prevalence of hepatitis A virus antibody in urban Yugoslav children aged 0-7 years, 18.2% were positive; most of them were only a few months old. The maternal origin of antibody in these very young children could be inferred from the rapid decrease of antibody during the first 5-7 months of life, following which period until the age of 7 years, there was no significant increase in the proportion with antibody. It was concluded that the age range included in this study (0-7 years) does not represent a time of life when most urban Yugoslav children come into contact with hepatitis A virus.
在一项针对0至7岁南斯拉夫城市儿童甲型肝炎病毒抗体流行率的研究中，18.2%的儿童呈阳性；其中大多数儿童只有几个月大。这些幼儿抗体的母体来源可从出生后前5至7个月抗体迅速下降推断出来，在此之后直至7岁，有抗体儿童的比例没有显著增加。研究得出结论，本研究涵盖的年龄范围（0至7岁）并非大多数南斯拉夫城市儿童接触甲型肝炎病毒的年龄段。
