  • Hepatitis B virus infects the liver, and more than 350 million people in the world are lifelong hepatitis B virus carriers.
  • Long-term hepatitis B virus infection causes at least one million premature deaths every year from cirrhosis of the liver or liver cancer. It is second only to tobacco as the leading cause of cancer in humans.
  • Among the Hepatitis B carriers, 25% will develop serious liver diseases, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
