Imported Malaria and Congenital Acquisition in Infant, Portugal, 2024.

Plasmodium falciparum infection was diagnosed in a 3-month-old baby in Portugal by optical microscopy. The mother had had malaria in Angola 13 months earlier, before she emigrated to Portugal. She remained asymptomatic throughout and after pregnancy. We confirmed the diagnosis of an imported malaria case and congenital transmission using molecular techniques.
