Abstract
Background:
Transfusion-transmissible infections (TTIs) remain a major public health concern in resource-limited settings. This
study aimed to determine the seroprevalence of HBV, HCV, HIV, and syphilis among blood donors in Ngounié province,
Gabon, an area previously lacking epidemiological data.
Methods:
A cross-sectional study was conducted from July 2025 to March 2026 at the Mouila Regional Hospital Center. A total
of 482 donors were screened using rapid immunochromatographic assays. Sociodemographic data and behavioral risk
factors were collected and analyzed using Python.
