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 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 individuals (> 50 years), blacks, and homosexuals or bisexuals showed increased exposure to HBV. The low frequency of individuals immunized against HBV, high social vulnerability, and risk behaviors emphasize the need for health services administrators to provide more opportunities for HBV vaccination in this target population.
巴西针对无家可归者（这一处于边缘地位且性传播感染风险高，包括乙型肝炎感染风险高的人群）的乙型肝炎感染情况的数据有限。本研究旨在调查巴西中部戈亚尼亚一个公共收容所中无家可归者的乙型肝炎流行病学情况。2014年8月至2015年6月，对353人进行了访谈并检测了乙肝病毒感染标志物。总体乙肝病毒感染率为21.8%（95%置信区间：17.82 - 26.41），19.5%（95%置信区间：15.75 - 24.0）呈现出过乙肝病毒疫苗接种的血清学特征。年龄较大者（>50岁）、黑人以及同性恋者或双性恋者乙肝病毒暴露风险增加。乙肝病毒免疫接种个体的低频率、高社会脆弱性以及风险行为强调了卫生服务管理者有必要为这一目标人群提供更多乙肝病毒疫苗接种机会。
