Inquérito sorológico da infecção pelo vírus linfotrópico humano de células T (HTLV) em comunidades amazônicas localizadasnas margens do Lago da Usina Hidrelétrica de Tucurui/PA

Abstract

The aim of this study was to evaluate seroprevalence lymphotropic virus human T cells (HTLV) in individuals living in communities of Alcobaça e Ararão, located on the shores of lake Hydroelectric Plant Tucuruí / PA. Serum samples from 657 individuals were analyzed by immunoenzymatic assays the type of ELISA (Symbioys ®). There was a significant prevalence of HTLVI / II (4.7%) in the study population and the demographic characteristics reflects most of them are older than 40 years (p = 0.0239), unmarried (p = 0.035), resident for over 10 years in the catchment area of the study (p = 0.0027) and educational level was equal to or less than 4 years (p = 0.0308). There was no statistically significant difference when analyzing variables such as sex, birth, blood transfusion and previous surgery. The prevalence for HTLV is considered high according to current literature, justifying the screening for this virus at the study sites in order that we can better understand the epidemiology of HTLV transmission in the population.
