Drugs that are inexpensive to manufacture and simple to administer greatly expand the potential to help tens of millions of people who need treatment for chronic hepatitis B virus (HBV) infection. Key program implementation challenges include identifying who would benefit from antiviral medication and ensuring long-term and consistent treatment to people who feel well. The best opportunities are where health systems are advanced enough to effectively address these challenges and in settings where HIV service platforms can be leveraged. Research, innovation, and collaboration are critical to implement services most efficiently and to realize economies of scale to drive down costs of health care services, drugs, and diagnostics.
