Viral Hepatitis in the United States Navy and Marine Corps

摘要

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.
