Identifying barriers to hepatitis B and delta screening, prevention, and linkage to care among people who use drugs in Philadelphia, Pennsylvania, USA

This study identified major gaps in HBV and HDV service delivery for PWUD, including poor basic knowledge, the need to address this through culturally appropriate, non-stigmatizing and tailored educational programming, and challenges with access to vaccination and testing. Continued initiatives are needed to close disparities, and to continue to provide financial and political support for harm reduction organizations, a frequently cited facilitator of healthcare access for PWUD. Significant efforts are essential to address lack of vaccination, testing, and linkage to care, and to improve health outcomes among PWUD.
