Every year on 28 July, countries around the world observe World Hepatitis Day, a global campaign dedicated to raising awareness about viral hepatitis and encouraging action to prevent, diagnose and treat the disease. The date commemorates the birthday of Nobel Prize-winning scientist Dr Baruch Blumberg, who discovered the hepatitis B virus and later helped develop the first vaccine against it.
Despite remarkable advances in prevention and treatment, hepatitis B remains one of the world's deadliest infectious diseases. It silently affects hundreds of millions of people, many of whom do not know they are infected until irreversible liver damage has already occurred.
Unlike many illnesses that quickly announce themselves through obvious symptoms, hepatitis B often progresses unnoticed for years. This silent nature has earned it the reputation of being a "silent killer." Yet it is also one of the most preventable viral infections, thanks to a safe, highly effective vaccine that has been available for decades.
