The total number of cases who came to donate blood was 150 donors aged 18 to 60 years;48 were excluded for several reasons. Several examinations were conducted for participants that were accepted for a study (n = 102 [2 (2.0%) were women and 100 (98.0%) men]), the prevalence of SARS-CoV-2 in nasopharyngeal samples was 11.8%. The mean CD4 count was 763.23 ± 194.61 cells/μl with endpoints [250 - 1400] cells/μl. IgG antibodies were present in 62.75% of cases. No statistically significant relation was found between SARS-CoV-2 carriage and IgG level or CD4 level (p = 0.850 & 0.056). Concerning the blood group, 57.3% (58) of the donors were of blood group O Rhesus positive;19.4% (20) of blood type A Rhesus positive;and 2.9% were of blood group A Rhesus negative. Pupils and students represented 35.3% of our population, followed by employees at 25.5%. The SARS-CoV-2 positivity rate was 11.8% (n = 12). The transfusion transmitted infections (TTI) rate was 12.8% with 1.2% (1) positive HIV serologies, 5.8% (6) positive for HBsAg, 3.9% (4) for HCVAb, and 1.9% (2) positive TPA.
