Hepatitis B Overview
Most commonly transmitted by sex, contact with blood, or via childbirth, hepatitis B virus (HBV) infection can lead to serious, chronic disease in about 5 to 10 percent of people it infects. HBV slowly damages the liver and can lead to liver failure and liver cancer. People with chronic HBV usually can’t be cured, but they can be treated. Vaccination against HBV is available and is recommended for a number of people.
