A hepatitis B virus carrier is called a big three positive?

Patient's question:

Hepatitis B virus carrier for 10 years

Doctor's answer:

Hello, a hepatitis B carrier refers to a person who is positive for hepatitis B surface antigen but has normal liver function.
Advice: The "big three positive" () refers to the presence of three markers: hepatitis B surface antigen, hepatitis B E antigen, and hepatitis B core antibody. The "big three positive" often indicates active replication of the hepatitis B virus in the body. If liver function and hepatitis B DNA are both normal, it is possible to get married.
Hepatitis B is transmitted through the following routes: blood transmission; sexual transmission; mother-to-child transmission; close contact transmission. Hepatitis B is not a digestive tract transmission disease, so eating will not transmit hepatitis B.
If you get married, it is essential to ensure that the female partner has hepatitis B surface antibodies before considering pregnancy. After the child is born, they must receive the hepatitis B vaccine at 0, 1, 6 months to protect them.
Lifestyle care: People with hepatitis B should pay attention to the following in their daily lives: a light, high-calorie, high-protein, easily digestible diet; avoiding smoking and alcohol; getting adequate rest and avoiding overexertion; and regularly checking hepatitis B markers, liver function, and hepatitis B DNA every three months to monitor the condition.
