The ways of hepatitis B transmission can be categorized into the following three ways. 1. Transmission through blood: it refers to the infection of hepatitis B through transfusion of blood of hepatitis B patients. 2. Through mother-to-child transmission: mother-to-child transmission is the main way of hepatitis B infection, most of the hepatitis B patients are transmitted from mother to child, born with hepatitis B virus, the state allows mothers with hepatitis B to have their babies free of charge to receive hepatitis B vaccine, hepatitis B immunoglobulin injection. 3. Transmission through sexual contact: Sexual contact transmission is that one of the husband and wife has hepatitis B virus and infects the other through sexual contact. It is recommended to go to regular hospitals for regular checkups for early detection and treatment, and hepatitis B antibody can also be produced through injection of hepatitis B antibody.
