Transmissão verticalO parasita pode ser transmitido tanto por via placentária quanto pelo leite materno.[7] A transmissão representa cerca de 13% das mortes durante o parto em algumas partes do Brasil.[8] Em Minas Gerais cerca de 1% das grávidas tem chagas. [9] Em alguns municípios do Brasil o número de grávidas contaminadas chega a 33%, enquanto em outros os casos são raros. A pasteurização do leite materno pode previnir a transmissão da doença.[10]
Não existem ainda medidas que evitem a transmissão vertical do parasita, logo a estratégia de controle da infecção congênita é centrada no diagnóstico precoce da infecção em recém-nascidos de mães infectadas e em tratamento específico imediato das crianças ao nascimento. Não se trata o Chagas durante a gravidez pois é difícil acompanhar eficazmente as reações do feto no útero. Felizmente, crianças tratadas ao nascer tem altos índices de cura.[11]
