Whether or not you will be infected after you have recovered from hepatitis B depends on the specific situation. If there is antibody against hepatitis B virus in the body, the chance of infection is lower, if there is no antibody against hepatitis B virus in the body, even after self-cure, there is still a possibility of infection. 1. Antibodies in the body: after recovering from hepatitis B virus infection, the body produces hepatitis B surface antibodies, and when exposed to the virus again, the body’s immune system will eliminate the virus, so the possibility of being infected with hepatitis B virus again is lower. 2. No antibody in the body: although the infection of hepatitis B virus is positive to negative, but the body does not produce antibody, when exposed to the virus again, it is still possible to be infected. Whether there is antibody in the body after hepatitis B self-cure, you need to go to the infectious disease department of the hospital, do a liver function test and hepatitis B five tests to determine the specific situation, and choose whether you need to inject the hepatitis B vaccine under the guidance of the doctor to ensure that you will not be infected by the hepatitis B virus again.
