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 chronic 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
