Resumo
Transplacental transmission of Trypanosoma cruzi has been the focus of much attention in
highly endemic areas in South America. Frequency of congenital transmission and factors
associated with risk of it are still not well understood. Parasite strains may account for part of
the geographical variation observed. Methodological differences between the studies do not
permit a combined interpretation of results. This paper examines the epidemiological data
available from Brazil, Bolivia, and Argentina and discusses possible epidemiological study
design to investigate risk factors for transmission.
