Between 1989 and 1992, 92% of a sample of 2790 Service recruits aged between 17 and 35 years (mean age 19 years 7 months) were found not to be immune to infection by hepatitis A virus. The proportion of males with immunity was consistently greater than that for females. There was a significantly increased probability of immunity if individuals originated from Northern England, the Midlands and Scotland, in particular the suburbs. Among male recruits there were significantly increased probabilities of immunity associated with travel to Southern and Eastern Europe or to the Tropics, and for females with travel to North West Europe or to Southern and Eastern Europe.
在1989年至1992年期间，对2790名年龄在17至35岁之间（平均年龄为19岁7个月）的新兵样本进行检测，发现92%的人对甲型肝炎病毒感染没有免疫力。有免疫力的男性比例始终高于女性。如果个体来自英格兰北部、中部地区和苏格兰，尤其是郊区，其有免疫力的概率会显著增加。在男性新兵中，前往南欧和东欧或热带地区的人有免疫力的概率显著增加；在女性新兵中，前往西北欧或南欧和东欧的人有免疫力的概率显著增加。
