Hepatitis-B antigen in an isolated Indian population (Yanomama indians) Southern Venezuela

A Soyano et al. Rev Bras Pesqui Med Biol. 1976 Dec.

Abstract

A high frequency of Hepatitis-B antigen (7%) was found in apparently healthy Yanomama indians living in southern Venezuela. The prevalence in 24 different Yanomama villages varied between 0 and 30%, but only 3 of 938 serum samples showed presence of HB-Ab. The distribution of the HB-Ag was found to be significantly higher in males than in females.
