Hepatitis B is a contagious and sometimes persistent infection that can lead to lifelong liver disease (chronic). The primary mode of transmission for the hepatitis B virus (HBV) is through blood, semen, or other body fluids. Risk factors include sexual contact, sharing needles or syringes, and sharing personal items such as razors or glucose monitors with an infected person. The virus is not spread casually (holding or shaking hands, hugging, sneezing, or talking to an infected individual). Hepatitis B can also be transmitted from an infected mother to her baby at birth. HBV can survive outside the body for at least 7 days.
A vaccination is available to prevent hepatitis B.
