Hepatitis B Cases by Country
Explore comprehensive Hepatitis B statistics by country using 2022 WHO estimates and national reporting data from 169 countries worldwide. The dataset highlights the global distribution of chronic HBV infections and helps researchers, healthcare professionals, and policymakers compare disease burden across regions.
This dataset tracks estimated chronic Hepatitis B (HBV) infections across 169 countries in 2022 using WHO-based reporting and national prevalence estimates. The figures highlight the unequal global distribution of HBV, with the largest burdens concentrated in parts of Asia and sub-Saharan Africa.
Global Hepatitis B Statistics 2022
Chronic Hepatitis B remains one of the world's largest infectious disease burdens, affecting hundreds of millions of people worldwide. While vaccination programs have reduced transmission in many regions, HBV continues to place major pressure on healthcare systems in highly endemic countries.
Key Takeaways
- China reported the highest estimated Hepatitis B burden in 2022 with 79.7 million chronic infections.
- India followed with 29.8 million cases, while Indonesia recorded more than 17.5 million cases.
- Nigeria ranked among the most affected countries in Africa with roughly 14.4 million chronic HBV infections.
- Dataset covers 169 countries using 2022 WHO-based Hepatitis B estimates and national reporting data.
Understanding Hepatitis B
Hepatitis B is a viral infection that affects the liver and can cause both acute and chronic disease. The virus spreads primarily through infected blood, birth-related transmission, or other bodily fluid exposure. Chronic HBV infections can persist for decades and remain a major cause of cirrhosis and liver cancer worldwide.
Largest Hepatitis B Burdens Are Concentrated in Asia and Africa
China accounted for the largest estimated chronic HBV burden in the dataset with 79.7 million cases, followed by India at 29.8 million and Indonesia at 17.5 million. Nigeria ranked as the largest African burden with 14.4 million estimated cases, while Ethiopia, Vietnam, and the Philippines also reported several million chronic infections each.
The overall distribution shows a strong concentration across Asia and sub-Saharan Africa, where long-term endemic transmission remains more common. Large population size plays a major role in total case counts, although prevalence rates can differ substantially between countries.

Vaccination and Prevention Programs
The Hepatitis B vaccine has been widely used since the 1980s and remains one of the most effective prevention tools against chronic HBV infection. Many higher-income countries significantly reduced transmission through universal childhood vaccination, blood screening programs, and improved infection control practices.
However, vaccination coverage and access to screening still vary widely across regions. In several lower-income countries, limited healthcare access and underdiagnosis continue to contribute to persistent long-term HBV burdens.
About the Data
The figures shown here represent estimated people living with chronic Hepatitis B infection in 2022 based primarily on WHO reporting, modeled prevalence estimates, and national health data. The dataset reflects chronic HBV burden rather than annual new infections or mortality figures.
Frequently Asked Questions
Q: Which countries have the highest Hepatitis B infection rates?
A: Based on 2022 data, Nigeria leads with over 14.3 million cases, followed by Indonesia, 17,544,081 (17.5 million), Pakistan (3.7 million), and Vietnam (6.5 million). The Western Pacific and African regions account for approximately 68% of all chronic Hepatitis B infections globally. These high numbers are primarily due to large populations, historical endemic transmission, and varying levels of vaccination coverage.
Q: How effective is the Hepatitis B vaccine in preventing infection?
A: The Hepatitis B vaccine is highly effective, providing 95% protection against infection when the complete vaccine series is administered. The vaccine has been available since 1982 and is considered one of the safest and most effective vaccines available. Countries with universal infant vaccination programs have seen dramatic reductions in Hepatitis B prevalence, with some achieving near-elimination status. The WHO recommends vaccination for all infants within 24 hours of birth, followed by 2-3 additional doses to ensure complete protection.
