Hepatitis B Virus – Epidemiology – Americas Data
DRG Epidemiology’s coverage of hepatitis B virus (HBV) infection comprises epidemiological estimates of key patient populations across 45 countries. We report the total prevalence of HBV infection for each country, as well as annualized case counts projected to the national population.
The patient populations are forecast over a period of ten years for all the countries covered in this report.
All forecast data are available on the DRG Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is also provided for full transparency into research and methods.
DRG Epidemiology's HBV infection forecast will answer the following questions:
- How will changes in HBV vaccine coverage impact the prevalence of HBV infections?
- Of all the people diagnosed with HBV infection, what percentage in each country across the major markets are drug-treated?
- How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of HBV infection over the forecast period?

Alison Isherwood, M.Sc., M.Res., Ph.D., is a senior director on the Epidemiology team at Clarivate. She specializes in female cancers, biomarker, and infectious disease epidemiology, particularly involving the impact of vaccination. She holds a B.Sc. in medical microbiology, a master’s degree in research in the life sciences (specializing in virology and parasitology), and an M.Sc. in epidemiology, all from the University of Edinburgh. She also holds a Ph.D. in molecular virology from the University of Reading in England.
Mike Hughes, M.Sc., Ph.D., is the director of the Epidemiology department at DRG, part of Clarivate. He joined DRG in 2006 and has many years’ experience in the mathematical modeling of healthcare service delivery, cardiovascular and cancer epidemiology, biostatistics, meta-analysis, and systematic reviewing. He has been principal author on many published articles in leading international journals in the areas of risk modeling in intensive care and cardiovascular medicine. He also helped develop national guidelines on behalf of NICE and the American College of Chest Physicians for the treatment of atrial fibrillation, stroke, and hypertension. He is particularly interested in modeling patient flows in cancer and methods for forecasting disease burden in noncommunicable epidemiology. Dr. Hughes received his Ph.D. in risk modeling in intensive care in 2003 from City University, London, and his Ph.D. in statistical causation and foundations of probability theory from the University of Nottingham.
