title: Increased seroprevalence of hepatitis B in dental personnel necessitates awareness of revised pediatric hepatitis B vaccine recommendations.
abstract: This article presents data regarding occurrence of hepatitis B in health care workers and children living in their households. Also reviewed are recent revisions in pediatric hepatitis B vaccine recommendations. The purpose of this discussion is twofold: to provide information to assist dental personnel in the decision-making process regarding vaccination of infants, children, and adolescents in their households; and to increase knowledge to facilitate educational presentations. In the United States from 1979 to 1989 the prevalence of new acute hepatitis B cases increased by 37 percent. An estimated 1.25 million people with chronic hepatitis B are capable of infecting those within their immediate environment, including their families. Studies indicate that dental health care workers, through occupational exposure, may have a 10 times greater risk of becoming a chronic hepatitis B carrier than the average citizen. The World Health Organizations's Expanded Programme on Immunizations recommends that children receive vaccination in populations where hepatitis B is prevalent. The three-pronged approach for reducing pediatric transmission includes: (1) vaccination of infants born to infected mothers, (2) routine vaccination of children born to hepatitis-seronegative mothers, (3) identification and vaccination of specific groups of adolescents. Comprehension of these changes may increase compliance regarding vaccination of children in our household, as well as enhancing our educational presentations to patients, the community, and professional societies.
