“Today, more than 500 million persons worldwide are living with viral hepatitis and do not have adequate access to care—increasing their risk for premature death from liver cirrhosis and liver cancer. Each year, more than 1 million people die from viral hepatitis and millions of new infections add to this global burden of disease and death.

This first World Hepatitis Day honors the man who achieved one of the greatest and earliest successes in viral hepatitis prevention—Dr. Baruch Blumberg, discoverer of the hepatitis B virus in 1967. He later developed an effective vaccine and won the Nobel Prize for his efforts. His discoveries were the first in a series of tools developed to combat viral hepatitis: diagnostic tests, new therapies and vaccines.

Vaccines are clearly making a difference today. The hepatitis B vaccine is now offered to children in 178 countries worldwide, providing a level of protection that prevents more than 700,000 deaths from cirrhosis and liver cancer in each new generation. And because hepatitis D requires the presence of hepatitis B virus to cause infection, hepatitis B vaccination eliminates the risk of contracting hepatitis D. A vaccine that prevents hepatitis A has been effectively used since the 1990s. In development are promising new vaccines against Hepatitis E, a common cause of water- borne hepatitis in Asia and Africa that disproportionately kills pregnant women. Unfortunately, vaccines against hepatitis C infection remain elusive.

Besides effective vaccines, tests for viral hepatitis have made the blood supply safer by dramatically lowering the risk for transfusion-associated hepatitis B and C infections. And for persons living with hepatitis B and C, improved access to screening and referral for treatment can reduce disease and death. Today, new therapies for hepatitis C can eliminate the virus in 3 out of 4 persons treated, essentially curing their infection.”
