It is a major cause of severe acute and chronic hepatitis B. The objective of this study was to determine the prevalence and risk factors of HDV in blood donors. <strong>Methods:</strong> This was a descriptive, cross-sectional study involving HBsAg-positive blood donors covering the period from July to December 2020. Testing for HDV RNA was performed by conventional two-step RT-PCR. Data were analysed using SPSS version 22 software. <strong>Result: </strong>Of 113 HBsAg positive samples included in the study 22 or 19.5% were HDV positive. The prevalence of HDV was higher in the age group 31 - 45 years (45.5%), in male donors (71.4%) and in donors with secondary education (50.0%). Furthermore, 55.4% belonged to the family donor category. A significant statistical difference was observed between HDV infection, tattoos, piercings and multiple sexual partners. <strong>Conclusion:</strong> This study shows a high prevalence of HDV among blood donors in Brazzaville.展开更多

The main objective of our study was to evaluate the seroprevalences of viral markers B and C in blood donors in the Agadir region. The secondary objectives were to evaluate these prevalences according to the socio-demographic characteristics of the donors and to evaluate the seroprevalence of other markers, in particular the human immunodeficiency virus. Methods: A retrospective analysis of files from the blood donor registers of the Agadir regional transfusion center, covering the period from 1 January to 31 December 2020, was conducted. Results: The study included 13,092 donors, the mean age was 34 ± 11, the M/F sex ratio was 2.6. The overall seroprevalences of HBsAg, anti-HCV, anti-HIV were respectively: 1.3%, 0.2% and 0.3% respectively. For HBsAg, the prevalence was higher in men (p = 0.007). The prevalence of anti-HCV was higher in rural areas than in urban areas (p Conclusion: The low prevalences of viral markers B and C in our study compared to those recorded in the general Moroccan population reflect the effectiveness of preventive measures with regard to donor selection.展开更多
