title: Viral hepatitis in homosexual men.
abstract: We studied 33 episodes of acute viral hepatitis in homosexual men to determine the type of hepatitis seen in this population. Seventy percent were caused by type A hepatitis, and 30% by type B hepatitis. None were due to non-A, non-B hepatitis. A high proportion of patients presenting with either type of acute hepatitis had evidence of previous infection with the other type: Seventy percent of patients with type B hepatitis had previous infection with type A, and 74% of patients with type A hepatitis had previous infection with type B. This study shows that, in homosexual men, hepatitis A, like hepatitis B, is a sexually transmitted disease.
