World Hepatitis Day is July 28th

World Hepatitis Day is recognized annually on July 28th, 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.

Hepatitis viruses can cause inflammation of the liver, chronic viral hepatitis infection can lead to cirrhosis and liver cancer. Viral hepatitis is a major global health threat with around 240 million people living with chronic hepatitis B and around 150 million people living with chronic hepatitis C.[1,2]

In order to raise awareness of this hidden epidemic, the World Health Assembly and the President of the United States Link external to CDC. See the legend on right-hand side. Also the 'Policies' link in page footer and subsequent 'Website Exit Notification/Disclaimer' link.have designated July 28th as World Hepatitis Day.

Organizations around the world, including the World Health Organization (WHO) and CDC, 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.

Viral Hepatitis: A Global Perspective

One million people die each year from chronic viral hepatitis. These deaths are primarily from cirrhosis or liver cancer caused by Hepatitis B and Hepatitis C.

Many of those who are chronically infected are unaware of their infection. People can live with chronic viral hepatitis for decades before having symptoms or feeling sick. So even though a person has no symptoms and may appear healthy, damage to their liver can still be occurring.

Viral hepatitis is among the top 10 infectious disease killers. Both chronic Hepatitis B and chronic Hepatitis C cause approximately 80% of the world's liver cancer.
