Trypanosomas and leishmanias can cross the placenta. Trypanosoma cruzi (American trypanosomiasis or Chagas' disease) may infect the placenta, with or without fetal transmission (congenital trypanosomiasis). Congenital transmission of Chagas' disease is a real problem of public health. Risk of congenital infections is less important for African trypanosomiasis and leishmaniasis. However, physicians should always think of this diagnosis in individual cases, since these diseases may occur in any part of the world, including outside the endemic areas.
锥虫和利什曼原虫可穿过胎盘。克氏锥虫（美洲锥虫病或恰加斯病）可能感染胎盘，无论是否发生胎儿传播（先天性锥虫病）。恰加斯病的先天性传播是一个切实存在的公共卫生问题。对于非洲锥虫病和利什曼病而言，先天性感染的风险相对较小。然而，医生在个别病例中应始终考虑到这种诊断，因为这些疾病可能发生在世界任何地区，包括流行区以外。
