“…(3) The finding was similar to that found in other Brazilian prison complexes, as that of Goiânia (0.7%, CI95% 0.0-4.3) (20) and Mato Grosso do Sul (0.5%, CI95% 0.08-1.9). (21) The serological investigation in the prison of the city of Ribeirão Preto, Southeastern region of Brazil, presented a higher rate (2.4%) because, unlike the findings of this study, behaviors such as the use of injectable drugs and sharing of syringes were shown and strongly associated. (22) In comparison with other countries, the rate was also low, such as in Iran (3.3%) and Spain (2.6% CI95% 0.2-4.9).…”

Objective: To estimate the prevalence of HBsAg marker in prisoners of the Brazilian prison system, correlating it to associated factors. Methods: An epidemiological, cross-sectional study was conducted in prison units with closed or semi-open regime (n=12), totaling 2,131 participant prisoners. Data were collected in an interview, followed by rapid testing for Hepatitis B (HBsAg). Simple, bivariate and multivariate descriptive analyses were carried out, with the use of logistic regression with the p value settled at 0.05. Results: The prevalence of positive HBsAg was 0.5%, with a statistically significant association with the variables "does not like to wear condoms" (ORa=3.63) and "does not know how to prevent sexually transmissible diseases" (ORa=5.02). Conclusion: The estimated prevalence was equal to or lower than that found in the general population of the country and the results proved that there are factors statistically associated with the prevalence of HBsAg positivity in the studied population. ResumoObjetivo: Estimar a prevalência do marcador HBsAg em internos de sistema prisional brasileiro, correlacionando-a a fatores associados. Métodos: Pesquisa epidemiológica, transversal, realizada nas unidades prisionais com regime fechado ou semiaberto (n=12), totalizando 2.131 internos participantes. A coleta de dados ocorreu por meio da realização de entrevista, seguida de testagem rápida para Hepatite B (HBsAg). Foram realizadas análises descritivas simples, bivariadas e multivariadas, utilizando-se a Regressão Logística com o valor de p fixado em 0,05. Resultados: A prevalência de HBsAg positivo foi de 0,5%, com associação estatisticamente significativa com as variáveis "não gostar de utilizar preservativo" (ORa=3,63) e "não saber como prevenir infecções sexualmente transmissíveis" (ORa=5,02). Conclusão: A prevalência estimada esteve igual ou menor que a encontrada na população geral do país e comprovou-se que existem fatores estatisticamente associados à prevalência de positividade do HBsAg na população estudada.

“…Seropositivity for HBV markers in our study (18.9%) was three fold higher than that found in a female population aged 13 to 69 years in the Midwest Region of Brazil (6.6%) 20 . Further, the present prevalence was higher than that found in female prisoners in São Paulo (n=225; 8.4%; 95% CI: 5.3-13.0) 15 but was similar to those reported by Stief et al 21 in Mato Grosso do Sul (n=242; 14%; 95% CI: 10-19.2) and in other countries such as England (n=400; 12.2%; 95% CI: 9.3-16) 22 , and the United States of America (n=555; 26%; 95% CI: [24][25][26][27] 23 .…”

“…Nonetheless, only a low frequency of individuals vaccinated against hepatitis B has been observed. In Rio Claro (southern region) and Campo Grande (midwestern region), serologic evidence of previous vaccination was found in only 13.8% and 32.3% of the prisoners investigated, respectively 15,21 . Our investigation indicated a similar rate, as only 24% of the women were anti-HBs positive alone, suggesting previous vaccination against HBV.…”

Introduction:Little information regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian female prisoners exists. This study investigated the prevalence and risk factors associated with HBV and HCV infections and identified viral genotypes among female prisoners in Goiás, Central Brazil. Methods: Women incarcerated in the largest prison in the State of Goiás were invited to participate in the study. All female prisoners were interviewed and tested for the detection of hepatitis B surface antigen (HBsAg), antibodies against HBsAg (anti-HBs), against hepatitis B core antigen (anti-HBc), and antibody against HCV (anti-HCV) by ELISA. HBsAg and anti-HCV positive samples were tested for HBV DNA and HCV RNA and genotyped, respectively. Results: Participants (n=148; 98.6%) completed the study with an overall HBV prevalence of 18.9%. Age >30 years, a low education level, sex with a sexually transmitted diseases carrier, and a male sexual partner serving in the same penitentiary were associated with HBV infections. Only 24% of the women were anti-HBs positive suggesting previous HBV vaccination. Nine female prisoners (6.1%) were anti-HCV positive. Age >40 years, injecting drug use and length of incarceration were statistically associated with anti-HCV antibodies. Five samples were HCV RNA positive and classified as genotypes 1 (subtypes 1a; n=3 and 1b; n=1) and 3 (subtype 3a; n=1). The HBsAg-reactive sample was HBV DNA positive and genotype A. Conclusions: These findings highlight the necessity of public policies to control hepatitis B and C infections and emphasize the importance of hepatitis B vaccination in prison environments.

Introduction: By the nature of their activities, firefighters are exposed to a high risk of contracting hepatitis B virus (HBV) as most of the Fire Brigade occurrences in Campo Grande, State of Mato Grosso do Sul (MS), Brazil, are related to the rescue of victims of traffic accidents and the transportation of clinical and psychiatric emergencies. The aim of this study was to investigate the seroepidemiological profile of HBV infection in firefighters from the City of Campo Grande, central Brazil. Methods: The research involved 308 firefighters. After giving written consent, they were interviewed and blood was collected for the detection of HBsAg, anti-HBs and total anti-HBc of enzyme-linked immunosorbent assays (ELISA). Results:The participants had an average of 36.4 years of age (SD ± 6.5), being 89.9% male. Blood tests revealed 6.5% of seropositivity for hepatitis B (HB) infection (n=20), and 1% for HbsAg. Isolated anti-HBs markers, indicative of vaccine immunity, were found in 66.9% of the participants and 28.2% were susceptible to infection. With regard to risk factors for HB infection, multivariate regression analysis showed a statistically significant association with length of service; and prevalence was higher in individuals with over 20 years of service. Conclusions: The prevalence of HB found among the firefighters was low and length of time in the profession was found to be a risk factor. Non-occupational risk factors did not influence the occurrence of HB infection in the population studied. Keywords: Hepatitis B. Firefighters. Occupational hazards. RESUMO Introdução:Os bombeiros pela natureza de suas atividades possuem elevado risco para aquisição da infecção pelo vírus da hepatite B (VHB), pois a maioria das ocorrências atendidas em Campo Grande, Estado do Mato Grosso do Sul (MS), Brasil, estão relacionadas ao resgate de vítimas de acidentes de trânsito e transporte de emergências clínicas e psiquiátricas. O objetivo deste estudo foi investigar o perfil soroepidemiológico da infecção pelo HBV em bombeiros do município de Campo Grande, Brasil Central. Métodos: Participaram da pesquisa 308 bombeiros. Após consentimento, foram submetidos à entrevista, coleta de sangue e testes sorológicos para detecção dos marcadores HBsAg, anti-HBs e anti-HBc total por enzyme-linked immunosorbent assays (ELISA). Resultados: A média de idade dos participantes da pesquisa foi de 36,4 anos (±6,5 DP), sendo 89,9% do sexo masculino. Foi encontrado percentual de soropositividade de infecção para hepatite B (HB) de 6,5% (n=20), sendo 1% para o HBsAg. A presença do marcador anti-HBs isolado, indicativo de imunidade vacinal foi encontrada em 66,9% e 28,2% dos indivíduos estavam susceptíveis à infecção. Com relação aos fatores de risco para infecção pelo VHB, a análise de regressão multivariada demonstrou associação estatística significativa com o tempo de serviço, sendo a prevalência maior em indivíduos com mais de 20 anos de serviço. Conclusões: A prevalência de HB encontrada nos bombeiros foi baixa, sendo encontrado...
