HUMAN IMMUNODEFICIENCY VIRUS (HIV) SEROPREVALENCE AT THE NATIONAL BLOOD TRANSFUSION CENTER (CNTS) IN N’DJAMENA-CHAD.

Introduction: To assess the seroprevalence of the human immunodeficiency virus (HIV) in blood donors. Materials and methods: This is a retrospective study carried out at the CNTS in N’Djaména (Chad) over a period of 5 years (2012-2017). Consulting registration registers and exam bench sheets, incomplete files were excluded from the study. The parameters studied were sex, age and HIV serology. Results: 110648 donors were included in the study, 2.07% (n = 2292) had at least positive HIV serology. The male sex is much more infected 0.77%. The 17-27 and 28-38 age groups are 0.47%, 0.27% respectively. Conclusion: At the N’Djamena national blood transfusion center, HIV seroprevalence is lower than in the general population. This high percentage of HIV should prompt the CNTS and technicians to improve laboratory tests and screening facilities such as rapid tests detecting AgP24 and even PCR.
