 Screening: Hepatitis B Virus Infection   (Site not responding. Last check: 2007-10-12)
The current practice of vaccinating all infants against HBV infection and postexposure prophylaxis with hepatitis B immune globulin administered at birth to infants of HBV-infected mothers substantially reduces the risk for acquiring HBV infection.
The prevalence of HBV infection is low; the majority of infected individuals do not develop chronic infection, cirrhosis, or HBV-related liver disease.
As a result, the USPSTF concluded that the potential harms of screening for HBV infection in the general population are likely to exceed any potential benefits.
