Abstract

Prevalence, risk factors and hepatitis B immunization: helping fill the gap on hepatitis B epidemiology among homeless people, Goiânia, Central Brazil Prevalência, fatores de risco e imunização contra a hepatite B: ajudando a preencher as lacunas na epidemiologia da hepatite B entre pessoas em situação de rua em Goiânia, Goiás, Brasil Prevalencia, factores de riesgo e inmunización contra la hepatitis B: ayudando a completar las lagunas en la epidemiología de la hepatitis B entre personas sin techo en Goiânia, Goiás, Brasil Goiânia, Central Brazil. From August 2014 to June 2015, 353 individuals were interviewed and tested for markers of HBV infection. Overall HBV prevalence was 21.8% (95%CI: 17,82-26,41), and 19,5% (95%CI: 15,75-24,0) showed a serological profile of previous HBV vaccination. Older Abstract Data are limited in Brazil on hepatitis B infection among homeless individuals, a marginalized population with high risk of sexually transmissible infections (STI), including hepatitis B. The aim of this study was to investigate hepatitis B epidemiology in homeless persons lodged in a public shelter in

HIV infection, high-risk behaviors and substance use in homeless men sheltered in therapeutic communities in Central Brazil

“…2,7 Many have high-risk behaviors, such as inconsistent condom use, multiple sexual partnerships, exchange of sex for money and/or drug use, and injecting and non-injecting drug use. [8][9][10][11] In addition, sociodemographic (for example: income and low education) and social (for example: absence of family contact) characteristics have been reported as determinants of HIV infection in homeless people. 9 Recent systematic literature review and meta-analysis including several countries (Switzerland, USA, India, Ireland, Iran, France, and Brazil) estimated a prevalence of HIV infection in homeless men of 5.0% (95.0% CI: 3.0-6.0%).…”

The prevalence of anti-HBc antibodies ranged from 10.4% to 80.3% (past infection) and that of HBsAg ranged from 0.6% to 4.7% (ongoing infection).…”
