[Some new cases of congenital human African trypanosomiasis (T. gambiense) (author's transl)].

The authors report three cases of congenital transmission of T. gambiense. In two cases, the parasite has been found in the blood of the umbilical cord. In the third case, it has been found twenty hours after birth in the peripherical blood of a new born child whose mother was affected by trypanosomiasis. They report also two cases of pregnant mothers with sleeping sickness, whose children were born-unaffected by the disease. The authors believe that the placental transmission of the human african trypanosomiasis is more frequent than thought.
