World Hepatitis Day 2025

World Hepatitis Day is annually held on July 28 to promote awareness of hepatitis, a disease that affects the liver.

What Do People Do

Organizations such as the United Nations and the World Hepatitis Alliance work with individuals and community groups to promote awareness raising campaigns worldwide about hepatitis. Information about World Hepatitis Day is usually distributed via social media, newspapers, posters, and through the World Health Organization (WHO) website.

Background

Hepatitis simply means inflammation of the liver and can be caused by different things. One of the most common causes of chronic (long-term) hepatitis is viral infection. According to the World Hepatitis Alliance, about 500 million people are currently infected with chronic hepatitis B or C and 1 in 3 people have been exposed to one or both viruses.

The World Hepatitis Alliance first launched World Hepatitis Day in 2008. Following on, the UN declared official recognition of this event in 2010.

Symbols

There is a different theme for World Hepatitis Day each year. Past themes included “Get tested” and “This is hepatitis”.
