A hepatitis B carrier is a patient whose liver function is normal and whose hepatitis B DNA is positive. Such a patient does not need treatment and regular review is sufficient. Because in this state, generally known as the immune tolerance period, antiviral therapy at this time is not effective and is not advocated. For chronic hepatitis B, there is no cure for either the active stage of hepatitis B or hepatitis B carriers. Hepatitis B can only be controlled at this time, and is not yet in a condition to be completely cured. If hepatitis B is in the active stage, the main treatment is antiviral therapy. Antiviral treatment is a long-term process, usually taking at least 4 years, and some people need to take medication for life. After antiviral treatment, the patient’s hepatitis B DNA is negative, liver function is normal, and hepatitis B major triplet can be converted to minor triplet, for such patients will also achieve the purpose of treatment.
