[Seroprevalence survey of human Chagas' infection (1975-1980)].

The results of the Serological survey for the prevalence of chagasic infection in Brazil, 1975/1980, were published before (Camargo et al, 1984) but the detailed geographical distribution is described in this paper. This was an initiative of two governmental bodies: the Superintendencia de Campanhas de Saúde Pública a Ministry of Health Division in charge of all public health policies, and, the Research National Council of the Ministry of Science and Technology through a program called Integrated Program for Endemic Diseases. Results obtained were extremely useful for a precise delimitation of the area with endemic transmission of Chagas disease, and hence, to direct the activities for vector control, which were implemented from 1975 onwards.
