1. Marriage: Since hepatitis B virus is mainly transmitted through blood, it will not infect others through the respiratory tract or normal digestive tract, and general contact will not cause transmission. According to the relevant national regulations, hepatitis B virus carriers are not affected by further education, employment, going abroad, marriage, childbirth, etc.. If the spouse is already positive for surface antibody and has normal liver function, you can get married. If the spouse is completely negative for hepatitis B indicators, you can get married after three months of hepatitis B vaccination. As long as the body has produced protective antibodies (i.e. positive surface antigen), you will not be infected. Hepatitis B patients should not get married during the active hepatitis period. The strain and sexual activity before and after marriage will increase the burden on the liver and aggravate the liver disease. When a hepatitis B patient can get married depends mainly on the liver function test. Acute hepatitis disease is short, can be cured in half a year after marriage. Chronic hepatitis patients, should be in stable condition after treatment, liver function normal one year after marriage is good. Due to the lack of health knowledge, social misunderstanding and exaggerated advertising, many carriers and their families are under great mental stress, and even cases of lovers breaking up, withdrawing from marriage, getting divorced and lightly living. In fact, for hepatitis B virus carriers, there are no restrictions on marriage. 2, reproductive problems: female hepatitis B virus carriers can completely pregnancy, childbirth. But women in acute and chronic hepatitis active and cirrhosis are not suitable for pregnancy. Because the fetus needs a large supply of nutrients, pregnancy will increase the burden on the liver of pregnant women, often aggravating the original liver disease, but also increase the obstetric complications during delivery, endangering the safety of mother and child. Therefore, patients with active hepatitis should be treated, and after one year of normal liver function, under the guidance of a doctor, choose the right time to conceive. After pregnancy, attention should be paid to rest and nutrition, and liver function should be checked regularly. For male hepatitis B patients, if the liver function is normal and stable, it does not affect fertility. 3. Prevention of newborns: Since mother-to-child transmission is an important transmission route for hepatitis B virus, newborns born to hepatitis B virus carriers and hepatitis B patients should be injected with hepatitis B vaccine and hepatitis B immune globulin (HBIG) within 24 hours of birth, and the hepatitis B vaccine should be administered according to the 0, 1, 6 program (i.e., once at birth, once at 1 month, and once at 6 months) to complete the whole process for a total of three times in order to To achieve the purpose of interrupting mother-to-child transmission. More than 95% of newborns can be protected from hepatitis B virus infection through hepatitis B vaccine and hepatitis B immunoglobulin.
