World Hepatitis Day (July 28)

Viral hepatitis is a major global health threat with an estimated 296 million people living with chronic hepatitis B and 58 million people living with chronic hepatitis C worldwide in 2019. World Hepatitis Day is observed annually on July 28, the birthday of Dr. Baruch Blumberg (1925-2011). Dr. Blumberg discovered the hepatitis B virus in 1967 and two years later developed the first hepatitis B vaccine and for these achievements won the Nobel Prize.

World Hepatitis Day is one of eight official disease-specific world health days designated by the World Health Organization. The annual observance focuses attention on the huge impact of viral hepatitis infection globally – with more than 350 million people worldwide living with either chronic hepatitis B or C.

Organizations around the world and across the United States use World Hepatitis Day to raise awareness of the problem and what needs to be done to strengthen efforts in prevention, screening and control of viral hepatitis.
