Unusual forms of malaria transmission. A report of 2 cases.

Malaria is uncommonly acquired without mosquito transmission. Two patients presenting with malaria illustrate this rare phenomenon. The first was a 1-month-old child who had received an exchange blood transfusion for severe haemolytic anaemia due to ABO blood incompatibility. The second was a doctor who had taken blood from the first patient. The occurrence of both transfusion malaria and accidental malaria from the same blood transfusion must be very uncommon.
