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.
Esta revisão integrativa tem como objetivo analisar as publicações científicas nos últimos doze anossobre triatomíneos encontrados no Estado do Ceará. Para tal, nos bancos de dados da Biblioteca Virtualem Saúde (BVS) foi realizada uma busca com associação dos descritores “Doença de Chagas”,“Triatomíneos” e “Brasil”. Após aplicação dos critérios de inclusão, exclusão e da análise dos seusconteúdos, oito artigos realizados no Estado do Ceará foram selecionados para a análise do estudo.Algumas espécies de triatomíneos encontradas no Nordeste são de extrema importância epidemiológicapara o homem, pois estão associadas com domicílios humanos. As espécies mais predominantescom maior importância epidemiológica, com distribuição ampla no Ceará e presente no ambienteperidoméstico foram: Triatoma brasiliensis, Triatoma pseudomaculata, Panstrogylus megistus,Panstrogylus lutzi e Rhodnius nasutus. Várias espécies de triatomíneos tem a capacidade de transmitirTrypanosoma cruzi e de se adaptar com o ambiente peridoméstico e doméstico tornando o homemmais suscetível a infecção, sendo assim necessário estratégias de vigilância e controle do vetor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
