Human T-lymphotropic virus 1/2 infection among prisoners of a major penitentiary complex of Goiás State, Central-West Brazil.

Introduction: Studies on human T-lymphotropic virus 1/2 (HTLV-1/2) infection are scarce in incarcerated population. Therefore, this study estimated the prevalence of HTLV-1/2 infection among prisoners of the major penitentiary complex of Goiás State, Central-West Brazil, comparing it with available data from other Brazilian regions.

Methods: A cross-sectional study was conducted with 910 prisoners of the major penitentiary complex in the State of Goiás, Central-West Brazil.

Prevalence of overt and occult hepatitis B virus infection among an incarcerated population of Central-Western Brazil.

Brazilian prison complexes are characterized by overcrowded cells and precarious conditions, leading to chronically low vacancy. Brazilian studies involving overt and occult infection (OBI) in this population are still scarce despite the vulnerability of people deprived of liberty to hepatitis B. Therefore, this study estimated the prevalence of HBV infection (overall and OBI) in individuals deprived of liberty in prisons in Central-Western Brazil.

Epidemiological and Molecular Characteristics of HIV-1 Infection in a Sample of Men Who Have Sex With Men in Brazil: Phylogeography of Major Subtype B and F1 Transmission Clusters.

This study describes human immunodeficiency virus 1 (HIV-1) prevalence, associated factors, viral genetic diversity, transmitted drug resistance (TDR), and acquired drug resistance mutations (DRM) among a population of 522 men who have sex with men (MSM) recruited by the respondent-driven sampling (RDS) method, in Goiânia city, the capital of the State of Goiás, Central-Western Brazil. All serum samples were tested using a four-generation enzyme-linked immunosorbent assay (ELISA), and reactive samples were confirmed by immunoblotting. Plasma RNA or proviral DNA was extracted, and partial () gene including the protease/reverse transcriptase (PR/RT) region was amplified and sequenced.
