title: Hepatitis A: a serological study in the Canadian Armed Forces.
abstract: Sera were collected from 3958 Canadian Forces personnel, including recruits, personnel posted to bases in Canada and on rotation with United Nations Peacekeeping forces, and the crew of a Canadian destroyer. All sera were tested for the presence of anti-hepatitis A antibodies by a competitive radioimmunoassay. The overall prevalence of anti-hepatitis A antibodies was found to be 23.5% (3.2% to 40.0%). The incidence of viral hepatitis A, as measured by seroconversion in paired sera, was found to be 0.17% (0.01% to 1.42%). The study results support the existence of a direct relationship between increasing age and an increased prevalence of anti-hepatitis A antibodies.
