Hepatitis B cannot be cured. The current clinical medical conditions, only through long-term oral anti-hepatitis B virus drugs, the hepatitis B virus can be maintained in a particularly low range, undetectable from the blood circulation, but the hepatitis B virus still exists in the liver cells, and even trace amounts of hepatitis B virus exist in the blood circulation. The actual hepatitis B virus DNA is not detectable by clinical tests, so there is no significant change in the hepatitis B test after taking oral antiviral medication compared to before. If there is a significant change, the surface antigen of hepatitis B turns negative and the surface antibody of hepatitis B turns positive, then it can be declared that hepatitis B is cured and the anti-hepatitis B virus medication can be stopped. Otherwise, hepatitis B should still continue to take oral antiviral drugs. Once you stop using them in the middle, it is likely that the hepatitis B virus will multiply again and can be detected in the blood again.
