ResumoObjectivesTo evaluate the epidemiological and molecular features of HBV infection among recyclable waste collectors.MethodsThe 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.ResultsAmong 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).ConclusionsDespite 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.
