World Hepatitis Day
300 million people live with hepatitis — most don't know it. Test. Treat. Heal.
About
World Hepatitis Day on July 28 focuses on viral hepatitis — a group of infectious diseases caused by hepatitis A, B, C, D, and E viruses — which collectively affect hundreds of millions of people worldwide. Hepatitis B and C are the most serious: together they cause chronic liver disease leading to cirrhosis and liver cancer, accounting for 1.1 million deaths annually. Critically, most people living with chronic hepatitis are undiagnosed — the disease is often symptomless for decades, earning it the label of a 'silent epidemic.' Safe and effective vaccines exist for hepatitis A and B, and highly effective curative treatments exist for hepatitis C. Yet access remains deeply unequal: hepatitis C treatment that costs tens of thousands of dollars in high-income countries is available for a few hundred dollars in generic form, but many health systems do not prioritise procurement. World Hepatitis Day calls for universal testing, treatment, and the political commitment needed to eliminate viral hepatitis as a public health threat by 2030.
History
July 28 was chosen as World Hepatitis Day to mark the birthday of Nobel Prize-winning scientist Baruch Blumberg, who discovered the hepatitis B virus in 1967 and developed the first hepatitis B vaccine. The World Hepatitis Alliance established the day in 2008, and the WHO adopted it as an official global health day in 2010.
Where It's Observed
Cultural Context
US United States
The US has significant hepatitis C rates, concentrated among people who inject drugs and older adults infected through blood transfusions before modern screening. World Hepatitis Day drives testing campaigns and advocacy for insurance coverage of curative hepatitis C treatments.
KR South Korea
South Korea has relatively high hepatitis B prevalence, a legacy of mother-to-child transmission before universal vaccination was implemented. The national hepatitis B vaccination programme has dramatically reduced rates in younger generations, and World Hepatitis Day celebrates this progress while addressing remaining treatment gaps.
JP Japan
Japan has one of the world's highest rates of hepatitis B and C-related liver cancer, linked to wartime medical procedures and contaminated blood products. The government has run major hepatitis testing and treatment programmes since 2008, and July 28 is used to encourage testing among those who may have been exposed.
