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?

In her role at Decision Resources Group, Alison is currently an Epidemiology team lead as well as project managing custom epidemiology work in multiple therapy areas. Alison’s area of specialization at DRG is cancer, particularly breast cancer.

Sandeep is a dental graduate with a Master’s in Public Health with a specialization in Epidemiology and has been associated with DRG since June 2018. He works with a global team of epidemiologists in performing fully documented systematic reviews of published and grey literature on epidemiology of diseases and their risk factors. He also conducts analysis on descriptive epidemiology of major indications in mature and developing markets. Additionally, he supports the operational and strategic management of the team and wider business unit through collation of data from various sources.

Prior to joining DRG he had over 5 years of experience working with state and central government of India to plan, design and conduct large scale research and implementation projects on non-communicable diseases, tobacco cessation and childhood nutrition.
