[The role of immigration in the geographic distribution of the HBs antigen].
The study of HBs antigen frequency among almost 130 000 donors,--according to their place of birth--,shows a significantly higher frequency among foreign residents. The general frequency represents the arithmetic average between that of natives and that of foreign residents. The distribution of ad and ay subtypes is analogous to that observed in the different native countries.
