Age, sex, type of blood donor (voluntary non\u2010remunerated vs familial\/replacement) and fate of blood donation (selected vs discarded) did not affect the prevalence of malaria carriage. The lack of malaria prophylaxis as well as the manifestation of malaria symptoms within 2 weeks and 1 month preceding blood donation were significantly associated with high frequency of parasites carriage.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Malaria parasites carriage is frequent among blood donors in Yaound\u00e9.
