I. Marriage problem Hepatitis B virus carrier is a person who has positive hepatitis B serum index (i.e. “major tri-positive” or “minor tri-positive”), but no hepatitis symptoms and signs, normal liver function and liver ultrasound examination, and continues to observe no change for six months. If the liver function test is abnormal, then the patient is a hepatitis B patient. Since hepatitis B virus is mainly transmitted through blood, it does not infect others through the respiratory tract or normal digestive tract, and general daily contact does not cause transmission. According to the relevant national regulations, except for not being able to donate blood, hepatitis B virus carriers can engage in normal work, study and social activities. It does not affect further education, employment, going abroad, marriage, childbirth, etc. Some people mistakenly believe that if one of them is found to be “positive” in a marriage test, they need to be treated to make the major and minor triplets turn negative before they can get married. Because there is no special treatment in the world to completely remove the hepatitis B virus, the idea of waiting to get married after turning negative is extremely unrealistic. Due to the lack of health knowledge, social misunderstandings and exaggerated advertising, many carriers and their families are under great mental stress, and even breakups of lovers, withdrawal, divorce and lightness of life. In fact, there is no restriction on marriage for hepatitis B virus carriers. Because the hepatitis B virus can be transmitted through blood and sexual contact, you can get married if your spouse is already positive for surface antibodies. 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 produces protective antibodies (i.e. positive surface antibodies), 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 the marriage will increase the burden on the liver and aggravate the liver disease. When a hepatitis B patient can get married depends 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. Second, fertility problems female hepatitis B virus carriers can completely pregnancy, childbirth. But in the acute and chronic hepatitis active and cirrhotic liver function is not normal women should not be pregnant. Because the fetus needs a large supply of nutrients, pregnancy will increase the burden on the liver of pregnant women, often aggravating the existing liver disease, but also increase the obstetric complications during childbirth, endangering the safety of mother and child. Therefore, patients with active hepatitis should be treated, and after the liver function is normal, under the guidance of the 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, it does not affect the fertility. Third, the prevention of newborns Since mother-to-child transmission is an important transmission route of hepatitis B virus, therefore, according to China’s hepatitis B prevention and treatment guidelines, newborns of HBsAg-positive mothers should be injected with hepatitis B immunoglobulin (HBIG) at a dose of ≥100 IU within 12 hours after birth, while 10 μg of hepatitis B vaccine should be administered at different sites, and hepatitis B vaccine should be administered according to the 0, 1, 6 program (i.e. The hepatitis B vaccine should be administered once at birth, once at 1 month and once at 6 months. Newborns can also receive one dose of HBIG within 12 hours of birth, followed by a second dose of HBIG one month later, along with the first dose of hepatitis B vaccine 10 μg, and the second and third doses of hepatitis B vaccine 10 μg at intervals of 1 and 6 months, respectively. newborns can receive breastfeeding from HBsAg-positive mothers after receiving HBIG and hepatitis B vaccine within 12 hours of birth. More than 95% of newborns can be protected from hepatitis B virus infection by hepatitis B vaccine and hepatitis B immune globulin. from becoming a new generation of hepatitis B virus carriers and hepatitis B patients.
