A carrier of hepatitis B is a person who

  • A.harbours the virus without necessarily being ill
  • B.has recovered fully and cleared the virus
  • C.is immune following vaccination
  • D.is incubating the infection before symptoms

Answer: A

Chronic carriage means the virus persists, and many carriers feel entirely well while remaining infectious to others and at risk of liver disease themselves. Identifying them matters both for their own monitoring and for preventing transmission.
