Abstract
were: anti-HBc (1.03%), HBsAg (0.07%), syphilis (0.35%), anti-HCV (0.04%), human immunodeficiency virus (HIV - 0.02%) and Chagas disease (0.02%). No positivity occurred in this study with respect to human T-lymphotropic virus (HTLV) I/II markers. A study conducted by Salles et al. in 2001 showed that the prevalence of infectious diseases among donors was: 0.04% for HIV, 0.21% for hepatitis C virus (HCV), 0.06% for HTLV, 0.14% for Chagas’ disease, and 1.10% for syphilis. For hepatitis B virus, the prevalences found were 0.14% for anti-HBc and HBsAg, 1.68% for anti-HBc and anti-HBs, and 1.67% for anti-HBc in isolation (3) . As new technologies are developed, the discovery of new infectious agents and the reemergence of old threats are an ongoing challenge in blood banks. I believe that similar studies should be encouraged in order to reinforce the importance of characterizing the prevalence of these serological markers in the blood donor population. In conclusion, this study is of great scientific relevance and reinforces the importance in establishing the prevalence of serological markers in blood donors. These results increase the knowledge about the role of the educational measures that have been carried out and may support the structuring of new awareness-raising campaigns for spontaneous blood donation.
