Objective: Our study planned to investigate the current positivity rate and distribution of the serologic markers of TTIs among male blood donors of the White Nile state, Sudan.
Results: The overall reported seropositive cases of TTIs was 15.91%, and percentages of anti-Human immunodeficiency virus 1/2 (anti-HIV1/2), Hepatitis B virus surface antigen (HBVsAg), anti-Hepatitis C virus (anti-HCV), and anti-Treponema palladium (anti-T. palladium) were 2.61%, 5.57%, 1.40%, and 5.72%, respectively. Out of 10897 donors examined, 0.59% had a serological sign of multiple infections. Furthermore, the odds of testing positive for TTIs were higher in the 28-37 age group (OR: 2.620, 95% CI: 2.324-2.955) and lower in the 38-47 age group (OR: 0.671, 95% CI: 0.567-0.794) compared to individuals of 18-27 years old. Likewise, it is more in individuals of Kosti (OR: 1.122, 95% CI: 0.987-1.277) and Rabak (OR: 1.354, 95% CI: 1.188-1.543) localities compared to Al Douiem locality. Anti-HIV/anti-T. palladium (27.70%) and anti-HIV/HBVsAg (23.07%) were the most frequently detected serologic markers of co-infections, P = 0.002.
