Abstract

CATALAN-SOARES, Bernadette; CARNEIRO-PROIETTI, Anna Bárbara de F.; PROIETTI, Fernando Augusto  and  INTERDISCIPLINARY HTLV RESEARCH GROUP. Heterogeneous geographic distribution of human T-cell lymphotropic viruses I and II (HTLV-I/II): serological screening prevalence rates in blood donors from large urban areas in Brazil. Cad. Saúde Pública [online]. 2005, vol.21, n.3, pp. 926-931. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2005000300027.

Brazil may have the highest absolute number of HTLV-I/II seropositive individuals in the world. Screening potential blood donors for HTLV-I/II is mandatory in Brazil. The public blood center network accounts for about 80.0% of all blood collected. We conducted a cross-sectional study to assess the geographic distribution of HTLV-I/II serological screening prevalence rates in blood donors from 27 large urban areas in the various States of Brazil, from 1995 to 2000. Enzyme immunoassay (EIA) was used to test for HTLV-I/II. The mean prevalence rates ranged from 0.4/1,000 in Florianópolis, capital of Santa Catarina State, in the South, to 10.0/1,000 in São Luiz, Maranhão State, in the Northeast. EIA prevalence rates are lower in the South and higher in the North and Northeast. The reasons for such heterogeneity may be multiple and need further studies.
