This work benefited from the active support of the University of Yaoundé II-Soa, the Center National Blood Transfusion of Cameroon (CNTS) and especially of the Federation Cameroonian for Voluntary Blood Donation (FECADOBES) who, after offering us a one-year internship, entrusted us with the secretariat of several seminars and meetings of the actors blood donation. This has been of immeasurable contribution to our understanding of the operation of the blood management system in Cameroon. We also express our gratitude to the research team of the African Economic Extension Program (PAVEN) for its dynamism in data collection, and of course our gratitude to the whole team mobilized for reading and improving this work. By elsewhere, the views expressed in this work should be taken as specific to their authors.
