The prevalence of hepatitis B serologic markers in suburban paramedics

Abstract Urban emergency medical services personnel have documented hepatitis B virus (HBV) seropositivity rates ranging from 0.6% to 25%. We studied 85 suburban paramedics for Hepatitis B serologic markers. All paramedics answered a questionnaire describing age, race, duration of employment, known hepatitis exposure, blood transfusions, gamma globulin injections, and Hepatitis B vaccination. HBV surface antibodies (Anti-HB,) were present in 6 85 (7.1%) paramedics of whom one (1.2%) had reactive HBV core antibodies (Anti-HB c ). No paramedic had HBV surface antigen (HB s Ag). Seropositivity was not associated with duration of employment, or exposure to a patient with either jaundice (28.2%) or confirmed hepatitis B (20.0%) within the six months prior to testing. The 7.1% prevalence of HBV markers found in this group of suburban paramedics is intermediate between previously reported rates for urban paramedics. We conclude that prehospital personnel do not constitute a homogenous occupational category at risk for hepatitis B infection.
