| Summary: | The author emphasizes the importance of the congenital transmission of Chagas' disease and discusses the possible risk factors for transmission such as age, origin, obstetrical history and maternal form of disease. Exacerbation of infection during pregnancy is also considered as a possible risk factor for transmission. Besides, a relationship between the frequency of transmission and gestational age is presented. Concerning breast-feeding, the risk of transmission is directly related to the acute phase of maternal disease and bleeding nipples. The deleterious effects of chagasic infection on the fetus and newborn are also considered. A autora enfatiza a importância da transmissão congênita da doença de Chagas e analisa os possíveis fatores de risco tais como idade, procedência, história obstétrica e forma da doença materna. Considera a exacerbação da infecção na gestação como possível fator de risco e relaciona a freqüência de transmissão com a idade gestacional. Os riscos na transmissão pela amamentação são relacionados diretamente com a fase aguda da doença materna e, na fase crônica com o sangramento mamilar. São também abordados os efeitos lesivos da infeção chagásica ao concepto. |
