She presented high parasitemia at the time of delivery; 3. In both, the mother and her daughter, T cruzi was classified as DTU TcIV. The parasites were not found in the blood at birth and the infection was detected only three months later in an asymptomatic infant. As the mother and her child live in a highly endemic area, vector transmission could not be excluded during this period.engopenAccessAcute Chagas diseaseChildDiagnosisTrypanosoma cruziDTUsVertical transmissionOral outbreaktrypanosoma-cruziarticleCopyright INST MEDICINA TROPICAL SAO PAULO10.1590/S1678-9946202163048Infectious DiseasesParasitologyTropical Medicine1678-9946
