[Sequence of unusual Chagas infection transmissions in the same family: mother by blood transfusion and child congenitally, with a treatment-resistant strain of Trypanosoma cruzi]

Abstract

The authors present two cases of unusual transmission of Chagas infection in the same family: the mother by blood transfusion and her second child across the placenta. The child was diagnosed by chance and etiological treatment for both the mother and the child was ineffective in eradicating the parasitemia. At present, they continue to present the indeterminate form of the disease.
