Hepatitis B antigen and antibody in the U.S. Army. prevalence in health care personnel

Abstract

The prevalence of Hepatitis B surface antigen (HB(s)Ag) and antibody (anti HB(s)) seropositivity and the association of seropositivity with demographic, personal health, and professional experiences were studied in a cohort of Army Medical Department officer personnel. Serologic evidence of Hepatitis B infection was found in 5.0 percent of personnel and was associated with age, sex, place of birth, history of hepatitis, history of blood transfusion, and previous overseas assignments. Seropositivity rates were higher for patient care oriented officer personnel, especially for those in surgical specialties, and rose with increasing professional experience. These data present a composite of risk factors operative in the acquisition of Hepatitis B seropositivity and identify a cohort for prospective study.
