Objectives: To evaluate the epidemiological and molecular features of HBV infection among recyclable waste collectors., Methods: The participants were recruited from the dumping ground and recycling cooperatives in Campo Grande, Brazil, and were screened for hepatitis B and C, and HIV serological markers by ELISA, confirmed by PCR., Results: Among 278 participants, 63.7% (95% CI: 58.0-69.3) were considered susceptible to HBV infection. The prevalence rate of HBV exposure was 10.1% (95% CI: 6.5-13.6) and 0.4% (95% CI: 0.1-0.6) were chronic carriers. Age ≥45 years (AOR=7.15), history of homosexual contact (AOR=5.29), tattoo (AOR=4.92) and history of surgery (AOR=2.89) were factors associated with ever infection. Age 18-25 years (AOR=4.63), educational level ≥9 years (AOR=1.98) and knowledge about HBV transmission (AOR=3.08) were associated with serological HBV vaccination like profile (26.2%; 95% CI: 21.1-31.4)., Conclusions: Despite the availability and efficacy of HBV vaccine, this study found high HBV exposure and proportion of susceptible adults in a low endemic area. Vaccination and screening campaigns using accessible language to the economically disadvantaged populations can reduce the number of people susceptible to HBV infection., (Copyright © 2019 The Author(s).
