Testing and Public Health Management of Persons with Chronic Hepatitis B Virus Infection

On September 19, 2008, CDC published updated and expanded guidelines for testing for chronic Hepatitis B virus (HBV) infection and recommendations for public health evaluation and management for chronically infected persons and their contacts. Serologic testing for Hepatitis B surface antigen (HBsAg) is the primary way to identify persons with chronic infection with HBV infection.
Testing for HBsAg now is recommended for:
  • persons born in geographic regions with HBsAg prevalence of 2%
  • US born persons not vaccinated as infants whose parents were born in geographic regions with HBsAg prevalence of ≥8%
  • injection-drug users
  • men who have sex with men
  • persons with elevated ALT/AST of unknown etiology
  • persons with selected medical conditions who require immunosuppressive therapy
Testing continues to be recommended for:
  • pregnant women
  • infants born to HBsAg-positive mothers
  • household contacts and sex partners of HBV-infected persons
  • persons who are the source of blood or body fluid exposures that might warrant postexposure prophylaxis (e.g., needlestick injury to a health care worker)
  • persons infected with HIV
