Blood is one of the fundamental tissues of our body. Blood donation allows blood banks to meet hospital needs for blood components. Blood transfusion is an activity that carries a risk, originated by a series of causal actions derived from the individual characteristics of donors and patients. Blood components are biological products and as such, they can never be exempt from the risk of transmitting infectious diseases, such as hepatitis B, HIV, syphilis, among others. Thanks to the investigation of the donor database of the Blood Bank of Hospital Dr. Carlos Luis Valverde Vega and the annual statistics of the blood bank, the statistics referring to donations were obtained, according to the type, grade of acceptance and as well as the prevalence of mandatory screening infectious diseases in the blood bank, between the years 2015 and 2019, with the respective authorization of the corresponding scientific ethics committee. This study reported a prevalence for Anti HB Core of 0.99%, 0.14% for HBsAg, 0.11% for syphilis, 0.05% for hepatitis C, 0.02% for HIV and 0% for the disease de Chagas and HTLV I / II. By using the bases of this work, future analyzes with a similar premise may be developed in different blood banks of the different health centers in our country.
