Background: Hepatitis B Virus (HBV) remains a major public health concern among people who inject drugs (PWID) in Nigeria due to high-risk injection practices and limited healthcare access. This study evaluates the impact of a peer-led screening and linkage program aimed at improving HBV diagnosis and treatment among PWID in the Federal Capital Territory (FCT), Nigeria. Description: The intervention employed a cohort-based model in which trained peer educators conducted awareness sessions, distributed sterile needles and syringes, and facilitated access to screening and treatment services. A total of 1,500 PWID participated in six phases, each completing an eight-week peer education program covering harm reduction, HBV/HIV screening, and linkage to care. Baseline assessments revealed widespread needle-sharing and limited knowledge of HBV transmission. Effectiveness: The program screened all participants, identifying a 6.1% HBV positivity rate and achieving a 53% vaccination coverage for participants who are negative. Results showed a 45% reduction in needle-sharing behaviors and a significant increase in HBV awareness and prevention knowledge. PWID who tested positive were successfully referred for continued care. However, service delivery was challenged by supply chain disruptions, stigma, and law enforcement barriers. Conclusion: Findings underscore the effectiveness of peer-led interventions in reaching marginalized PWID populations and enhancing HBV-related health outcomes. Scaling up this model nationwide, alongside policy reforms to strengthen harm reduction services, is crucial for reducing HBV transmission. Future efforts should prioritize sustainable funding, expanded access to hepatitis treatment, and broader community engagement to ensure long-term impact. |
