[Characteristics of intrafamilial transmission of the hepatitis B virus: a case load contribution and review of the literature].
A total of 143 subjects have been investigated (83 adults and 60 children). All of them are relatives of 50 HBsAg carriers (26 females adults and 24 children). Relatives of these 26 females adults presents a intrafamilial prevalence of infection of 28.8% (40% in males partners). In the 24 paediatric cases, intrafamilial diffusion of HBV is more elevated 67% seropositives (72.4% of adults and 57.5% of children). Greater intrafamilial transmission of HBV are seen in chronic forms of disease. We do insist that is very necessary to investigate the immunity of HBV in relatives of HBsAg (+) subjects. Specific vaccination for those who will be seronegative should be indicated.
