A person who has positive surface antibodies (HBsAb or anti-HBs) has recovered and is no longer contagious to others. Once a person has recovered, which can take up to six months, they cannot pass the virus on to others.
Although a person who has recovered is protected against future hepatitis B infections, they are still at risk for other types of hepatitis viruses (i.e. hepatitis A and C). Therefore, they should get the hepatitis A vaccine and avoid risk factors for hepatitis C.
