Soroprevalência do vírus linfotrópico de células T humanas (HTLV) entre doadores de sangue em hemocentros de Maringá-Paraná e Boa Vista-Roraima

Abstract

OBJECTIVE: to describe human T cell lymphotropic virus (HTLV) seroprevalence among blood donors at blood centers in Maringá-Paraná and Boa Vista-Roraima. METHODS: this was a descriptive study of secondary data of tests on blood samples from first time and loyal donors in Maringá (2001-2010) and Boa Vista (2007-2010). RESULTS: 126,386 blood donations were studied in Maringá and 50,855 in Boa Vista. Based on the records of positive serology for HTLV between 2007 and 2010, the number of cases in Maringá remained low and stable, while in Boa Vista it increased from 1.6 to 11.2 positive cases per 10,000 donations. CONCLUSION: this study showed a different epidemiological profile among donors in the two cities. This suggests the need to increase actions with a more regionalized approach to preventing HTLV virus transmission in Brazil.
