[Blood safety: malaria and blood donation in Africa].
Malaria is a principal cause of mortality in Africa and represents a major blood-borne disease. The studies made on the continent show that transfusion-associated malaria is highly prevalent in blood donors groups and that some risk factors and clinical manifestations are frequently observed. The disease is mostly asymptomatic and the signs are mild, which reduces significantly an efficient selection of the blood donors during the predonation interview and a secure supply of blood products. Furthermore, the lack of appropriate screening assays of the malaria in blood banks on the continent limit the diagnosis of the disease and hamper the blood safety. However, the prevention of transfusion-associated malaria is a frequently asked question. The destruction of the parasite in the blood bag and the recipient anti-malarial prophylaxis are the described possibilities, added to local programs against the vectors of the disease.
