Background: Hepatitis B Virus (HBV) remains a major global health challenge, with significant morbidity and mortality associated with chronic infections. Methods: This study examines the epidemiology, screening, and risk factors associated with HBV in Romania, focusing on a comprehensive national screening program, LIVE(RO)2, involving 320,000 individuals (majority of them considered vulnerable population). A questionnaire was used to collect information on the potential risk factors for HBV transmission. Results: The overall prevalence rate of HBV chronic infection among all the participants tested was 1.67% (confidence interval: 1.63–1.72%), with significant differences (p = 0.0001) between participants from the main geographical regions of residence (North-East 1.89%, South 1.38%, South-East 2.06%, and South-West 1.54%). Male persons aged 30–49 or 60–69 years old, from the rural and Eastern parts of Romania and non-Romanian ethnia, with a low level of education, unvaccinated, not married, unemployed, with family members with hepatitis, with personal histories of blood or blood product transfusion, surgical interventions, tattooing, hospitalizations, imprisonment, haemodialysis, unsafe sexual contacts, or with sexual transmitted infectious diseases were risk factors associated with HBsAg seropositivity. Conclusions: Our findings highlight significant demographic and epidemiological patterns of reduced HBV prevalence even in vulnerable persons, as well as modified risk factors and the impact of socio-economic factors.
