Currently, the medical community is concerned about whether it is possible to marry a person with hepatitis B virus? The answer is yes, you can get married. If a positive hepatitis B antigen antibody system is found in the physical examination, it means that the person has been infected with the hepatitis B virus, and it is better to check the hepatitis B virus DNA. In this case, the patient should go to the hospital to receive regular treatment, and it is best to have a child when the hepatitis B virus DNA is negative. If there are indeed special reasons such as older age, or disease, or an unplanned pregnancy and there is a strong desire to continue the pregnancy. Experts at home and abroad have found more effective ways to interrupt mother-to-child transmission after a lot of clinical summaries. Please be sure to consult with a specialist clinic to give the best guidance. According to our statistics, the rate of hepatitis B virus carriage among pregnant women is 5%-10%, and the rate of mother-to-child transmission of hepatitis B virus is 20%-70%; if the mother is positive for hepatitis B e antigen, the transmission rate can be 75%-95%. Some statistics show that about 70% of infants born to hepatitis B virus surface antigen-positive pregnant women have the virus in their blood 1-3 months after birth. Since the immune system of infants is not yet mature, they are unable to clear the invasive hepatitis B virus, and once infected, they are likely to develop into asymptomatic hepatitis B virus carriers or turn into chronic hepatitis, and such infants are more likely to develop cirrhosis or even liver cancer when they grow up. In the mother-to-child transmission chain, the main transmission of hepatitis B virus from pregnant women to the next generation is mainly through the birth canal. The best way to avoid transmission of the hepatitis B virus to the infant is combined immune blockade, in which the hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) are administered to the infant at different sites on the buttocks within 12 hours of birth. Hepatitis B vaccine should be given within 24 hours after birth, at 1 month of age, and at 6 months of age, each at a dose of 10 μg (micrograms) of yeast genetically engineered vaccine or 30 μg of blood-derived vaccine, with a protective effect of up to 95% for newborns. For pregnant women with high viral quantification, they can take Class B nucleoside drugs, such as telbivudine or lamivudine, after 7 months of pregnancy, which can improve the success rate of blockade. However, special attention should be paid to the pre-requisite that the pregnant couple must be fully informed about the use of the drug. Over a long period of time, we have observed that, as long as the medication is administered under the close guidance of a specialist, the vertical transmission of hepatitis B virus from mother to child or father to child can be almost blocked by the rational combination of HBIG and hepatitis B vaccine, and the protection rate of infants is very high. Therefore, patients with hepatitis B need not worry too much, as long as they receive regular treatment, they can still have a healthy and lovely child.
