Hepatitis B virus carriers are an important source of infection of viral hepatitis B. Hepatitis B virus can be transmitted to others through direct or indirect contact, and now research shows that: Hepatitis B surface antigen is found in the patient’s saliva, semen as well as women’s vaginal secretions and menstrual blood, and it may be infectious through contact and sexual life. Therefore, when you find the blood HBsAg positive, you should be timely laboratory tests of liver function and five indicators of hepatitis B virus, HBVDNA quantitative test, if the liver function is normal, HBVDNA quantitative test negative (now the virus is not replicating), this situation can be married. If the liver function is not normal, of course, you can not get married, and should be treated in time. If liver function is normal, HBsAg, HBeAg anti-HBc are positive, indicating that the hepatitis B virus is actively replicating and highly contagious, in this case, you need to check the other person’s blood, such as the other person’s blood surface antibody (anti-HBs) is positive, indicating that the other person already has immunity to the hepatitis B virus, it is not easy to be re-infected, so you can get married. If the other person’s blood is negative for Hepatitis B surface antigen (HbsAg), surface antibody (anti-HBs) and core antibody (anti-HBc), it means that the other person is neither infected nor immune to Hepatitis B virus, so he or she will be easily infected after marriage, and it is not suitable to get married for the time being. Hepatitis B vaccine can be injected according to the program of 0, 1, 6, and the marriage can be conducted after 6 months when the body produces enough protective antibodies, which is a safer and more appropriate way to deal with the situation. During this period, the party carrying hepatitis B virus should actively use some hepatoprotective, immune adjustment and antiviral drugs for treatment, after reasonable treatment, HBeAg turn negative, the other party has produced protective antibodies before marriage is the most safe and appropriate. However, after marriage, one should abstain from sex and pay attention not to be overworked.
