Hepatitis B 25 positive is not contagious to others.
Hepatitis B 25 positive refers to hepatitis B surface antibody and core antibody positive. It means that you have been infected with hepatitis B virus, but your body has cleared the virus, and you are now cured of hepatitis B and have produced protective antibodies. Generally speaking, hepatitis B 25 positive is not contagious to others, so don’t worry too much.
Whether hepatitis B is contagious to others depends mainly on the replication status of the hepatitis B virus in the body. If the surface antigen of hepatitis B is positive, the DNA level of the hepatitis B virus in the body is high and in a highly replicating state, which is highly contagious and easy to infect others. The hepatitis B virus in the body is in a low replication state and is generally less infectious.
