Patient's question:
Recently I haven't been feeling well, so I went to the hospital for a thorough check-up. The doctor said I am an HBsAg carrier. So I'd like to ask a few questions: What is an HBsAg carrier?Doctor's answer:
A carrier of hepatitis B surface antigen refers to a state where, after being infected with the hepatitis B virus, the body's immune function and the virus's blood-borne pathogenicity reach a balance, and the virus does not replicate in large quantities again. However, the body is also unable to produce effective antibodies to completely clear the virus from the body. This constitutes a viral carrier state, making such patients an important source of hepatitis B virus transmission. These patients can spread the hepatitis B virus through blood products, sexual contact, and mother-to-child transmission, leading to the spread of hepatitis B.If the body's immune function is enhanced, it may produce antibodies to the hepatitis B virus, potentially leading to full recovery. Interferon-based antiviral treatment has a defined endpoint and can significantly increase the risk of future liver cirrhosis and liver cancer. Additionally, it can better facilitate the serological switch of hepatitis B E antigen.
