Hepatitis B should be prevented between husband and wife through measures such as condoms, vaccination and separate use of supplies. 1. Condom: Since hepatitis B can be spread through sexual contact, condom can be used to protect and block the spread of the disease. 2. Vaccination: the healthy spouse should be timely injected with hepatitis B vaccine, which can prevent hepatitis B after producing antibodies. 3. Separate use of supplies: patients’ personal toiletries, tableware, etc. should be used separately, and timely disinfection can also play a role in reducing infectiousness. Patients should quit smoking and drinking, eat a light diet, and go to the hospital regularly to check the liver function, and decide whether to use medicine under the guidance of the doctor.
