Patient's question:
I had a girlfriend before, and after living with her for over a year, I found out she had hepatitis B surface antigen (HBsAg) positive. During that time, we lived together. I heard that HBsAg positive can be contagious, and now I'm very upset. I haven't gone to the hospital for a thorough check-up, and I don't have any symptoms of discomfort. I want to know if having sex with a woman who is HBsAg positive can transmit it to me? What should I do?Doctor's answer:
Generally, hepatitis B tends to be hereditary. The vast majority of cases are transmitted during infancy due to the weakened immune system of the body, which gradually leads to chronic hepatitis B. After adulthood, as the human immune function gradually increases, if exposed to the hepatitis B virus, the vast majority of people can produce antibodies on their own. Therefore, there is absolutely no need to worry about your situation. Even if you and your girlfriend have had sexual intercourse, and she has hepatitis B with small positive, it is highly likely that your body has already produced antibodies.
