Hepatitis B immune tolerance refers to the hepatitis B virus enters the human body, reproduces and infects the human body, but the body’s immune system does not have a particularly obvious effect on the clearance of the hepatitis B virus, and the body’s immune system doesn’t destroy the hepatitis B virus infected hepatocytes or deal with them, so it’s called immune tolerance. In immune tolerance, the immune system does not clear the infected liver cells and liver function is mostly normal, but at this time, the amount of hepatitis B virus is relatively high and it is very likely to be a triple-positive state, and the quantitative result of hepatitis B virus in the blood is very likely to be more than five times ten, which is called hepatitis B immune tolerance. After the hepatitis B virus infects a person, the younger the person is, the younger the person may be immune-tolerant, resulting in hepatitis B virus carrier status, without any liver damage; infected in adolescence or adulthood, or after a child is infected with hepatitis B, in adolescence or adulthood, it is possible that immune-tolerance enters into immune-clearance, where the body’s immune system begins to clear the infected liver cells, and there will be obvious liver function abnormalities.
