“…The result is consistent with rates detected in Campinas 20 and Sorocaba 21 and with the general epidemiology for American prison inmates 4 . In one of several studies in the Carandiru prison complex, Lourenço 14 , in 1996, observed a higher prevalence (23%) among individuals 21-25 years of age.…”

HIV infection among prison inmates shows one of the highest prevalence rates for specific population subgroups, reaching as high as 17% in Brazil and elsewhere in the world. The present study aimed to estimate HIV antibody prevalence and risk factors for infection in male inmates at the Ribeirão Preto Penitentiary, São Paulo State, Brazil, from May to August 2003. Using simple random sampling, 333 participants were selected, answered a standardized questionnaire, and had blood samples collected. Enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence were used for HIV serological diagnosis. Overall HIV prevalence among inmates was 5.7% (95%CI: 3.2-8.2). All variables associated with HIV antibodies in the univariate analysis were submitted to unconditional multivariate logistic regression. Independent predictors of HIV infection were: total prison sentence less than five years and sharing needles and syringes.

Introduction:The aim of this study is to establish the prevalence of HIV infection and associated risk behaviours amongst inmates at the Montevideo Prison in 2005. Materials and Methods:The prevalence of HIV infection and different risk practices were analysed in a sample of 191 individuals by means of a serological study and personal interview based on a structured questionnaire.Results: A prevalence of 6.5% was found for HIV infection in prison. The variables that proved to be risk factors were: previous prison sentences (p=0.009; OR= 9.51; IC95%: 1.31-144.0), having had an HIV (+) sexual partner in the past (p=0.000025; OR=7.87; IC95%: 2.58-23.9), current relationship with an HIV (+) partner (p=0.0013; OR=14.24; IC95%: 2.84-70.65), intravenous drug use (p=0.0001; OR=22.6; IC95%: 6.87-78.9), intravenous drug use in prison (p=0.03; OR=4.93; IC95%: 1.10-22.81) and sharing needles (p=0.004; OR=12.5; IC95%: 1.72-114.7).

“…As there is no countrywide prison surveillance system in Brazilian detention centers, data on HIV prevalence, the prevalence of HIV resistance mutations, and HIV transmission networks in prisons are limited to observational surveys. There is considerable variation in the estimates reported by them, most were derived from studies in only one prison, and HIV-1 prevalence ranged from 1% to 16% [6,7,[9][10][11][12][13][14][15][16][17][18][19].…”

Higher rates of human immunodeficiency virus (HIV) infection have been detected in prisoners when compared with the general population, but research into HIV molecular epidemiology and its transmission network has been lacking among them. Thus, this study aimed to verify potential HIV molecular transmission networks among prisoners. In addition, we aimed to describe the mutations related to antiretroviral resistance in these isolates. Thus, we conducted a cross-sectional survey from 2013 to 2018 in prisons in Central-Western Brazil, and the final sampling composed of 84 prisoners. Proviral DNA was extracted from each whole blood sample followed by amplification of the partial polymerase gene and sequencing. Forty-nine sequences (58.3%) were classified as subtype B, followed by C (14.3%), D, and F1 (2.4% each). A complex and dynamic HIV-1 epidemic is observed in the prisons, as 25% of the sequences were recombinant forms. We detected 15 HIV transmission clusters composed of at least two sequences, that included not only prisoners but also individuals from the general population from the same State with a variety of risk behaviors. Thirty-two percent (32.0%) of treatment-experienced prisoners had at least one drug resistance mutation (DRM), while transmitted DRMs were found in 5.9% of the prisoners. We highlight the urgent need for routine surveillance of HIV-1 infection including resistance genotypic tests considering the high disease burden, risky behaviors inside prisons, and the dynamic relationship of prisoners with the outside community.
