Hepatitis B has a controllable effect on the body, and it is perfectly possible to have boyfriends and girlfriends just like healthy young people. Carriers have almost no effect on the body, and only need regular follow-up to prevent flare-ups. Even in chronic hepatitis, sustained remission or stable control can be achieved through antiviral treatment. Hepatitis B is not spread through daily contact, hugging, sharing meals or kissing. For men and women, it is best to get vaccinated against hepatitis B before close contact. Pre-marital sexual relations are discouraged to avoid harm to each other due to parental disapproval of Hepatitis B. Most healthy young people are immune to hepatitis B and can quickly clear the hepatitis B virus after infection. Only some immunodeficient people will develop chronic hepatitis, so whether and when to inform each other of the disease varies from person to person. Under normal circumstances, hepatitis B will not affect the health of the spouse, and will not affect the growth and development of offspring, hepatitis B patients can get married. However, as the spouse of hepatitis B patient, you have the right to know each other’s health condition before marriage, which is also one of the purposes of premarital examination. Before having sex, if the other person is negative for surface antibody, the couple needs to be vaccinated against hepatitis B. Condoms should be used for sex before completing the 3 vaccinations. As the spouse of the patient, he/she should have the correct concept that daily contact is not contagious, no need to share meals, and avoid discrimination within the family. Hepatitis B virus infection is not teratogenic to the fetus and does not cause congenital diseases. Mild hepatitis has no effect on pregnancy except for a higher rate of preterm labor. Early cirrhosis with good compensatory function has no significant effect on pregnancy. Pregnant women with incompletely compensated cirrhosis may develop acute liver failure, and the fetus has the potential for preterm labor, spontaneous abortion, and stillbirth. Pregnancy has little effect on liver function and pregnancy does not aggravate liver lesions. For those with high transaminases, enzyme-lowering drugs can be used to bring down the transaminases, and then the drugs can be stopped after the liver function is stabilized before pregnancy. Any medication may have an effect on the embryo, so it is better not to use medication in the early stage of pregnancy. Mildly elevated aminotransferases in the early stage of pregnancy can be left untreated, while those with markedly elevated aminotransferases need to be treated according to the needs of their condition. After 6 months of pregnancy, depending on the liver function, it can be appropriate to give enzyme-lowering treatment, which is often safer. The chance of intrauterine transmission is very low, mainly caused by slight placental abruption and leakage of mother’s blood into the fetal circulation. Avoiding strenuous exercise such as jumping and falling can reduce the risk of placental abruption, and intrauterine transmission is difficult to prevent, and there is no evidence that prophylactic injection of immune globulin can reduce the risk, so it is not recommended to use it routinely. The most important means of preventing mother-to-child transmission is for pregnant women with high viral loads. Nucleoside analogs such as tibivudine, which has been approved for use in pregnant women, can be applied in the sixth month of pregnancy and taken orally until one month after delivery, and newborns can be promptly vaccinated with hepatitis B vaccine and hepatitis B immune globulin after delivery, and the rate of mother-to-child transmission interruption is close to 100 percent. So far there is no evidence that the hepatitis B virus can be transmitted through breast milk, and hepatitis B is a blood-borne disease that is not transmitted through the digestive tract. Newborn babies are often vaccinated against hepatitis B and have protective antibodies, so even if they come into contact with the hepatitis B virus, they will not be infected. Therefore, mothers with hepatitis B can breastfeed their children, which is not only good for the child’s nutrition, but also helps to establish a close relationship between the mother and her child. Semen can contain the hepatitis B virus, but only the spermatozoa in the semen enter the uterus and combine with the egg, and it is usually not passed on to the child through the sperm. Therefore, young men and women infected with the hepatitis B virus are not affected by marriage or childbirth.
