PEREIRA MARTINEZ, Madeline M et al. Behavior of the serologic markers in blood donors in the territory of Colon, 1998-2007. Rev. Med. Electrón. [online]. 2012, vol.34, n.1, pp.25-33. ISSN 1684-1824.

We carried out a prospective descriptive longitudinal study on the behavior of the serologic markers in the Ultra-Micro-Analytic System laboratory, of the blood bank of the territorial university hospital Dr. Mario Muñoz Monroy, of the municipality of Colon, province of Matanzas. We determined the incidence and prevalence of the surface Hepatitis B virus antigen (HBV, HBsAg) and of the antibodies against the Hepatitis C (HCV, anti HCV) and the human immunodeficiency virus 1 and 2 (HIV 1 and 2, anti-HIV 1+2) in blood donors of the territory, and the estimate of non-detected potential infection transmissible by blood or residual risk (RR) in the donated blood, in the period from January 1st 1998 to December 31st 2007. The research was made with all the universe of utile donors and their respective blood donations, and was formed by 49 749 donors and 84 932 blood bags. The prevalence rates (x 100 000 donors), incidence (x 100 000 donors), and estimated residual risk (x 1 000 000 units of donated blood) in the quoted time period were: for the HBV 0,81; 0,17 and 0,20; for the HCV 0,55; 0,12 and 0,23, and for the HIV 1 and 2 0,005; 0,01x10-2 and 0,02x10-3 respectively, low rates according to the international classification, but not for Cuba with respect of the HBsAg.
