Infection caused by the hepatitis B virus (HBV) continues to have a major impact on global public health, even while being vaccine-preventable. People living on the streets, homeless, are at high risk for sexually transmitted infections (STIs), including hepatitis B. To investigate the epidemiology of HBV infection among homeless people in Goiania, Goias, from August 2014 to June 2015, 353 individuals served by a public shelter at the capital were interviewed using a structured questionnaire containing questions about socio-demographic characteristics, clinical and risk factors for HBV infection. Next, all were tested for serologic markers of HBV. It was observed the predominance of males (81.3%), mixed race selfdeclared (61%), single (59.8%), low income (70%) and low level of education (53,3%). The global prevalence of HBV was estimated at 21.81% (95% CI 17.82 to 26.41): two individuals were HBsAg / anti-HBc positive, 61 were anti-HBc / anti-HBs, and 16 showed reactivity to only the anti-HBc marker. Additionally, 19.55% (CI: 95%: from 15.75 to 24.00) tested positive for isolated anti-HBs, suggesting immunity to HBV. Analyzing potential risk factors to HBV showed that: age over 50 years, being gay or bisexual, and being mixed race/blackselfdeclared were independently associated of exposure to HBV. The results confirm the vulnerability of this populational subgroup and a high prevalence of exposure to HBV. Still. the low frequency of serological evidence of immunization against HBV, specially among older subjects, makes evident the need of drawing up strategies of vaccination at the support places to homeless.
