Review article: current gaps and opportunities in HBV prevention, testing and linkage to care in the United States-a call for action.

A 'scale-up' effort is needed to optimise the care continuum to achieve the WHO 2030 targets.

More active and system level interventions are also needed to improve linkage to care for patients with HBV infection.
