Congenital malaria: a rare cause of splenomegaly and anemia in an American infant.
A 38-day-old infant had fever, jaundice, hepatosplenomegaly, and a hemolytic anemia. A peripheral blood smear demonstrated intraerythrocytic malarial parasites identified as Plasmodium vivax. Maternal and infant sera contained antibodies to this species. A directed history revealed the mother had suffered several febrile illnesses in Mexico during her pregnancy. Malaria had not been diagnosed nor was it considered at the time of her delivery at this hospital. Review of this and six other cases of congenital malaria reported in this country since 1950 indicates clinical manifestations seldom appear before 3 weeks of age. Although these signs are more frequently associated with other transplacental infections, their occurrence in an infant whose mother is from or who has traveled in an endemic area should prompt consideration of the diagnosis of congenital malaria.
