Hepatitis B can be divided into acute hepatitis B, chronic hepatitis B and subclinical infection. Most adults are cured by subclinical infection after being infected with hepatitis B virus (these people are actually healthy at the time of examination, and the typical two-and-a-half results are 2, 4, 5 or 2, 5 positive), and a few develop acute hepatitis B. Acute hepatitis B generally goes through a benign process, and most patients can fully recover and gain immunity. A very small number of acute hepatitis B patients are infected with hepatitis B virus through mother-to-child transmission or childhood, and a small number of adult infected people eventually become chronic hepatitis B patients. Patients with chronic hepatitis B are defined as people who have been HBsAg positive for more than six months. Among patients with chronic hepatitis B, those with normal liver function are called "virus carriers" or "healthy carriers" in society, and those with abnormal liver function are called "hepatitis B patients" in society. But it must be clear that there is no obvious difference between "virus carriers" and "hepatitis B patients", and they can be transformed into each other in a very short time. At the same time, the so-called "healthy carrier" is just an irregular name in society. These patients are not healthy people, but patients with hepatitis B. Even if all the liver function test indexes of these patients are normal, the liver may already have severe inflammation, so it is impossible to think that normal liver function is a healthy person at all. We should check them regularly and find the problems in time.
