Based on the literature, this work aimed to discuss infection by Chagas disease among blood donors in Brazil. Studies on the prevalence of Trypanosoma cruzi infection in donors or candidates for blood donation in Brazil are important. The prevalence of infection appears to be a sensitive indicator and can be a true marker of the risk of the transmission of Chagas disease by blood transfusion. Moreover, it serves as a marker of the level of transmission of the disease in a region, as well as a tool to characterize the epidemiological profile of individuals affected by the disease. The present study is an integrative review of the literature on chagasic infection among blood donors. An evaluation of the literature identified the epidemiological profile of blood donors infected by T. cruzi , which is characterized in general as men, over 30 years old, with a low level of schooling, low income and mainly coming from rural areas.
