Geographical distribution of ABO and RHD antigens is important for blood transfusion services and population genetics studies. There are few data on this topic in Burkina Faso, a multi-ethnic country. Our study aims at reporting phenotypic and allelic frequencies of ABO and RHD blood groups among voluntary blood donors from various ethnical regions of Burkina Faso.

- Traditional serological tests like RPR and CMIA struggle to differentiate between venereal and non-venereal syphilis, prompting interest in molecular biology methods for accurate diagnosis.
- A study involving 6,375 blood donor samples in Burkina Faso assessed the diagnostic effectiveness of PCR testing compared to serological methods for identifying Treponema pallidum subsp pallidum.
- Results showed a low T. pallidum prevalence with PCR confirming only a small number of positive cases, indicating potential issues with cross-reactions and the presence of non-venereal treponemal infections.
Background: The goal of selecting a healthy blood donor is to safeguard donors and reduce the risks of infections and immunologic complications for recipients.
Study Design And Methods: To evaluate the blood donor selection process, a survey was conducted in 28 blood transfusion centers located in 15 francophone African countries. Data collected included availability of blood products, risk factors for infection identified among blood donor candidates, the processing of the information collected before blood collection, the review process for the medical history of blood donor candidates, and deferral criteria for donor candidates.
Background And Objective: The high prevalence of numerous transfusion-transmitted infectious diseases such as HIV, HBV, HCV and syphilis in sub-Saharan Africa affects blood safety for transfusion recipients. The aim of this study was to evaluate the prevalence and incidence of transfusion-transmissible infectious diseases among blood donors in Burkina Faso.
Methods: A retrospective study of blood donors' records from January to December 2009 was conducted.
Background: The high prevalence of numerous transfusion-transmitted infectious diseases such as human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis in sub-Saharan Africa affects the safety of blood for recipients. This study was undertaken with the aim of determining the seroprevalence of HIV, HCV, HBV, syphilis and socio-demographic risk factors associated with blood donation in a new regional blood transfusion centre in Burkina Faso.
Material And Methods: Sera samples were screened for hepatitis B surface antigen (HBsAg), antibodies to HCV, HIV types 1 and 2 and to Treponema pallidum using enzyme-linked immunosorbent assays and Rapid Plasma Reagin test (RPR) respectively.
Introduction: The World Health Organization (WHO) recommends the creation of national blood transfusion services. Burkina Faso has a CNTS (Centre National de Transfusion Sanguine-National Blood Transfusion Center) but it currently covers only 53% of the national blood supply versus 47% produced by independent hospital blood banks.
Study Design: To evaluate blood collection, testing, preparation, and prescription practices in the regions of Burkina Faso that are not covered by the CNTS, a cross-sectional survey was conducted.
