Prevention of hepatitis B virus infection.

Hepatitis B virus infection is the most important cause of acute and chronic liver disease worldwide. The Immunization Practices Advisory Committee has proposed a comprehensive strategy to eliminate the transmission of hepatitis B virus in the United States. The three phases of this strategy are prevention of perinatal transmission of the hepatitis B virus, universal vaccination of all infants against hepatitis B virus infection and selected vaccination of high-risk adolescents and adults. Because family physicians provide obstetric, perinatal, adolescent and adult care, they can have a major influence on the success of this strategy.
