title: [Prevalence of Australia antigen among children in rural populations of Senegal (author's transl)].
abstract: The 8 villages surveyed in the operational zone of Niarhar (Sine, Senegal, Africa) involved 1,182 children aged 0-14 years. 11.2% of these children showed a positive HB antigenaemia. The percentage of prevalence which was already high in the 0-1 year-old group (5.7%) increased progressively, attaining the maximum of 13.5% in the 5-9-year-old age group. The current theory that a higher frequency of HB antigenaemia is found among boys was confirmed, but there is no evidence that this "androtropism" is related only to sex. The rates of total prevalence vary from 7.1% to 16% according to the geographical regions. It was not possible to prove the existence of a possible relation between the different levels of prevalence on the one hand, and on the other hand the geographical position, size, structure, social and economic typology of the villages and the anopheline activity.
