Globally, malaria remains one of the most common transfusion-transmitted infections. It can have serious consequences, as Plasmodium falciparum infection can quickly become fatal. In sub-Saharan Africa, transfusion-transmitted malaria is a reality due to repeated, poorly or uncontrolled blood transfusions, where the majority of donors are potential carriers of hematozoa. This study aimed to determine the prevalence of asymptomatic plasmodium carriage among voluntary blood donors in the Sélingué health district. We conducted a prospective, cross-sectional study of 220 voluntary donors. The sample consisted of blood donors aged 18 to 65 years and weighing at least 55 kg. Diagnostic tests included the Rapid Diagnostic Test (RDT), Thick Blood Smear (GBS), and Thin Blood Smear. Our study found a prevalence of asymptomatic Plasmodium carriage among voluntary blood donors at 4% for the EG and 10% for the RDT. The average age of blood donors was 30.9 years, males were more likely, and married donors were positive in 100% of cases. Compensatory donations were the most affected, with a RDT positivity rate of 13% compared to 2% for voluntary donations, with a statistically significant difference (p = 0.01564). The majority of non-school-aged donors participated, with a participation rate of 58%, dominated by farmers (51%). Thick blood smears returned positive in 33% of donors who had a fever 4 days prior to donation. We confirm asymptomatic Plasmodium carriage among blood donors in the Sélingué health district. The combined commitment of all stakeholders will help address these challenges.
