Frequency of Blood Donation and Malaria Occurrence among Blood Donors in a Tertiary Hospital, Nigeria

Context: Malaria is a significant cause of morbidity and mortality in Sub-Saharan Africa (SSA). Transfusion transmitted malaria contributes significantly to the burden of malaria in SSA. The safety of blood transfusion as it relates to frequency of blood donation and malaria occurrence on the part of donors is an aspect that has not been properly investigated hence this study. Objectives: This study was conducted to assess the frequency of blood donation and occurrence of malaria among blood donors at OAUTHC, Ile-Ife. Materials and methods: This was a cross-sectional study. Ethical approval was obtained. One hundred and thirty-three consenting blood donors aged between 18-50 years were recruited for the study. Two millilitres of blood were collected from each study participant and immediately transported to the laboratory for processing. Giemsa-stained films of the samples were viewed under the oil immersion objective of the microscope. Questionnaires were administered to the study participants to obtain relevant information. Data generated were analysed using descriptive and inferential statistics with SPSS software version 20. The level of significance was set at p < 0.05. Results: The prevalence of malaria among the blood donors was 21.1% with the highest rate among commercial donors (33.3%) followed by family donors (12.9%) then voluntary donors (11.9%). Evaluation of the frequency of donation showed that malaria occurred more in recurring donors (77.78%) than first time donors (22.22%). Conclusion: Malaria is highly prevalent among blood donors and occurs more in recurring blood donors than first time donors.
