What are the chances of hepatitis B infection in adults without antibodies refers to the fact that the chances of developing chronic hepatitis in adults after exposure to the hepatitis B virus is about 5%. Hepatitis B surface antibodies protect against hepatitis B virus infection, which generally has a higher chance of developing chronic hepatitis B after infection with the hepatitis B virus in early childhood, and a lower chance of developing chronic hepatitis B after infection with the hepatitis B virus in adults without antibodies, which is usually around 5%. The most common type of hepatitis B infection in adults is occult hepatitis B, which means that they are unaware that they are infected with hepatitis B and their bodies have healed without them realizing it. Exposure to the hepatitis B virus has different regressions, which are very much related to the amount of virus infected and the body’s resistance. The stronger the resistance and the less infected the person is, the more likely he or she is to be cured. Only a small percentage develop chronic hepatitis B and most are carriers. If you find hepatitis B surface antibody negative, it is recommended that you get the hepatitis B vaccine to prevent hepatitis B.
