A person with surface antigen persisting beyond six months is regarded as having

  • A.immunity from a resolved infection
  • B.immunity conferred by vaccination
  • C.chronic hepatitis B infection
  • D.acute hepatitis B infection

Answer: C

Correct answer: chronic hepatitis B infection

Six months is the conventional dividing line. Surface antigen still present after that means the infection has not been cleared and is now chronic, with a lifetime risk of cirrhosis and hepatocellular carcinoma that requires monitoring. Its disappearance within six months marks resolution.
