Can hepatitis B, born healthy and carrying bacteria, be infected? Through what infection, my boyfriend has this disease, but he said it won't be infected.

Hepatitis B virus is not innate, let alone healthy. However, although some people are infected with hepatitis B virus, they have no symptoms or organic lesions. Such individuals are called healthy carriers of hepatitis B virus by the medical community. But such a healthy carrier does not mean that it will not be transmitted to others. The main routes of transmission of hepatitis B are vertical transmission from mother to child, blood transmission (for example, he has a bleeding spot on his body and you have a bleeding spot on his body. If these two places are in contact at the same time, there is a chance of being infected) and sexual transmission. If you have been injected with hepatitis B vaccine and produced antibodies, you will not be infected if you are in close contact with him. Therefore, if you are not sure whether you have antibodies, don't get in close contact. Take the time to go to the hospital to inject hepatitis B vaccine. After you really produce antibodies, you will be safe.
