To further evaluate the extent of a focus of onchocerciasis recently discovered in Northern Mountains of the Federal Territory of Rorairna. lt was in this region that the authors had previously found a woman missionary with onchocercal nodules. Fifty-seven lndians from several villages ("malocas") were examined, of which 27 (approxirnately 48 per cent) were found to have Onchocerca volvulus microfilariae in their skin. However, only five of Brazil, the authors have carried out a survey among the Yanomama lndians in the Surucucus these 27 (18.5 per cent) were found to have subcutaneous nodules. These findings support the previously presented hypothesis that onchocerciasis is endemic among the Yanomama Indians, who occupy a large expanse of territory on both sides of the Brazil- Venezuela border.
