Two analyses of the Navy and Marine Corps experience with viral hepatitis are reported. The first is longitudinal in nature and shows that over the past 100 years the syndrome has been common and at a relatively steady rate of 100-400 cases/100,000 average strength/year. The second is an examination of cases in calendar year 1974 for demographic, geographic, and occupational patterns. There is a strong inverse relationship between disease occurrence and age. Each type of viral hepatitis shows a distinct geographic distribution. Navy personnel in health-related occupations had a greater risk of acquiring viral hepatitis than did other persons on active duty. Differences among other occupational groups were found, but valid interpretations could not be made because of the small numbers of cases in each category.
本文报告了对海军和海军陆战队病毒性肝炎情况的两项分析。第一项分析本质上是纵向的，结果显示在过去100年中，该综合征较为常见，平均发病率相对稳定，为每年每10万人中有100 - 400例。第二项分析是对1974年病例的人口统计学、地理分布和职业模式进行研究。疾病发生率与年龄之间存在强烈的负相关关系。每种类型的病毒性肝炎都有独特的地理分布。从事与健康相关职业的海军人员感染病毒性肝炎的风险高于其他现役人员。在其他职业群体之间也发现了差异，但由于每个类别中的病例数量较少，无法做出有效的解释。
