Carrier is a word that appeared when most people in China didn't know much about it before. For hepatitis B, it is an unscientific word, because hepatitis B is caused by viruses, not bacteria.
Carrying bacteria and viruses is infected with hepatitis B virus, but like healthy people, they have no symptoms and normal liver function, which does not affect their lives. Such people need to pay attention to their diet and daily life and check their liver function regularly. They don't need any treatment, and they are not patients.
Hepatitis B patients refer to people who are infected with hepatitis B virus and have related symptoms and abnormal liver function, which is what we often call patients.
