Nearly 257 million individuals have contracted hepatitis B infection around the world. However, only 10% of them know about their illness. Mother to child transmission, nosocomial spread, and sexual transmission are the major etiological factors. Finding the missing millions is a global issue. Hepatitis B care is more difficult compared to hepatitis C as not all patients require treatment and the selection of patients is not straightforward. To eliminate hepatitis B infection, the program should screen pregnant women and start antiviral therapy from the 28th week of pregnancy if hepatitis B virus (HBV) DNA≥ 200,000 IU/mL or hepatitis B e-antigen (HBeAg) reactive. Prevention of perinatal infection, birth dose and neonatal vaccination, post-vaccination monitoring of high-risk groups, catch-up vaccination, and registration of the carriers should be an integral part of the program. Continuum of care is important when planning the elimination program from addressing the risk factors, testing, and referral for treatment. The program should integrate test and treat hepatitis services with existing local health care services. There is a need to create the right environment, raise awareness, remove stigma, and increase screening of those at risk and manage those who require treatment. A national policy should be prepared for capacity building, fund allocation, and implementation strategies. Micro-elimination strategies should boost national elimination effects. Guidelines to diagnose and treat patients with hepatitis B should be simplified. Surveillance should be done to monitor progress, and determine the impact of the elimination program on incidence and mortality, and services.
