“…According to a World Health Organization (WHO) report, only four transfusion-transmitted infections are tested for in Africa, namely, human immune-deficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis [ 3 ], malaria not being among them. In Nigeria, donated blood is also not routinely screened for malaria parasites before transfusion [ 4 ], but asymptomatic malaria parasitaemia has been demonstrated in 11% (Jos) [ 5 ], 6.8% (Zaria) [ 6 ], 16.4% (Lagos) [ 7 ], 40.9% (Abakaliki) [ 8 ], 30.2% (Nnewi) [ 9 ], 40% (Benin City) [ 10 ], and 41% (Ibadan) [ 11 ] of blood donors. As a result of the high rate of blood transfusions in our environment [ 12 ], the risk of blood transfusion-induced malaria (BTM) assumes significant health importance.…”

Background Asymptomatic malaria parasitaemia has been documented in donor blood in West Africa. However, donated blood is not routinely screened for malaria parasites (MPs). The present study therefore aimed to document the frequency of blood transfusion-induced donor-recipient malaria parasitaemia patterns, in children receiving blood transfusion in a tertiary health-centre. Methodology A cross-sectional, observational study involving 140 children receiving blood transfusion was carried out. Blood donor units and patients' blood samples were obtained, for the determination of malaria parasites (MPs). Giemsa staining technique was used to determine the presence of malaria parasitaemia. Results Malaria parasites were detected in 7% of donor blood and in 8.3% of the recipients' pretransfusion blood. The incidence of posttransfusion MPs was 3%, but none of these were consistent with blood transfusion-induced malaria, as no child with posttransfusion parasitaemia was transfused with parasitized donor blood. Majority of the blood transfusions (89.4%) had no MPs in either donors or recipients, while 6.8% had MPs in both donors and recipients, with the remaining 3.8% showing MPs in recipients alone. Conclusion In conclusion, the incidence of posttransfusion malaria parasitaemia appears low under the prevailing circumstances.
