In 1982 and 1985, an infant and a pregnant woman in the second trimester of her third pregnancy were respectively observed in Humaitá County, State of Amazonas, Brazil. Both had been diagnosed as having Plasmodium falciparum malaria. The infant was a boy bom in the State of Amazonas with malaria since the 10th day of life and was examined at one month of age. His mother was 19 years old, was bom in the State of Amazonas and had shown primary malarial infection on the day of the delivery of this child, her second. The pregnant woman was 22 years old, was bom in the State of Amazonas, had two children respectively aged 8 and 6 years and had suffered three previous bouts of malaria, the first in 1983 and the last in March 1985. Both the infant and the pregnant woman were treated with clindamycin and evolved satisfactorily to clinical and parasitic cure. The infant probably presented with congenital malaria in view of the short period of incubation, which may have been due to the fact that he did not receive maternal antibodies.
