Hepatitis B virus carriers, mostly referred to asymptomatic hepatitis B virus carriers (ASC), that is, the blood test alone positive hepatitis B surface antigen, but also said to refer to the hepatitis B antigen, antibody test positive various patterns of people (except for the surface antibody single positive), but no signs and symptoms of hepatitis, the various liver function tests are normal, and after six months of observation of the unchanged people. It is generally believed that hepatitis B virus carriers can work and study as usual. According to statistics, about one-tenth of the people in China may carry hepatitis B virus. The main reasons for its formation are mother-to-child transmission and exposure to hepatitis B virus in adolescents and adults with weakened immune function. Asymptomatic HBsAg carriers are categorized into 3 groups: 1. Those who have suffered from hepatitis and do not know it at all. Because of its clinical symptoms and liver damage is slight and quickly cured, only manifested as the HBsAg carrier state after the disease. 2. Healthy carriers, after repeated tests of liver function are normal, without any symptoms and signs, and even for liver biopsy also did not see pathological damage, liver tissue structure is intact. 3. Diagnosed by liver biopsy pathology for chronic prolonged hepatitis, chronic active hepatitis. The first group of asymptomatic HBsAg carriers should be followed up medically, and liver function should be rechecked once every 3 months in order to know whether there is any liver damage in time, and if there is any liver damage, it should be treated in time. The second group of asymptomatic HBsAg carriers can work, study and labor as usual, and most of them have a good prognosis, after a period of time, with the improvement of the body’s autoimmune status can be naturally negative. The third category of asymptomatic HBsAg carriers confirmed pathological damage to the liver, should be treated as a symptomatic patient, timely treatment. Asymptomatic HBsAg carriers are not really “healthy people”, these people have the virus in their bodies, and there is the possibility of replication or infection of others, so they should not be engaged in the food service industry and nursery work. HBsAg carriers should pay attention to personal hygiene and public hygiene, develop good hygiene habits, and the implementation of the meal system; do not mix with others in the use of food; do not mix with others in the use of food; do not mix with others in the use of food. Do not mix toiletries with others. Women should also pay attention to menstrual hygiene to prevent menstrual blood from contaminating daily necessities. At present, there are three main principles of medical treatment for asymptomatic HBsAg carriers: 1. Protect the liver: absolutely quit drinking, avoid overwork, keep a good mood, reasonable nutrition, regular recheck of hepatitis B viral markers and liver function, if necessary, can take ascorbic acid, Bao Gan Wei Nutritional Powder to enhance the body’s resistance and strengthen the nutrition of the liver, avoid blind use of medication. 2. anti-hepatitis B virus treatment: under the guidance of specialists to use drugs, such as interferon, Lamisil, and so on, and the use of interferon, Lamisil, and the use of interferon, Lamisil, and so on. Anti hepatitis B virus treatment: use medication under the guidance of a specialist, such as interferon, lamivudine, anti-hepatitis B immune ribonucleic acid, and proprietary Chinese medicines, etc. 3. Family personal hygiene treatment: other members of the family can be injected with hepatitis B vaccine to prevent infection. Asymptomatic HBsAg carriers can use 0.2% of 84 disinfectant to soak and wash (20 minutes), and the tableware can also be sterilized by steaming for 30 minutes or separated for use. In conclusion, hepatitis B virus carriers generally have good regression, a small portion of them can naturally turn negative; most of them are in a continuous and stable lifelong hepatitis B virus carrier status (about half of them have slight pathological changes in the liver, which is a relatively stable low response state of continuous hepatitis B virus infection and requires treatment.) ; however, about 3% can develop hepatitis and are also much more likely to develop liver cancer than non-carriers. Anyone who is positive for surface antigen (HBSAg), regardless of “major triple positive” “minor triple positive” liver function is normal, abdominal ultrasound without abnormality is hepatitis B virus carriers. China’s hepatitis B virus chronically infected about 120 million people, carriers accounted for 1/4, that is, 30 million, this group of people in the community has been subjected to a lot of unfair treatment, bear a huge spiritual burden, deserves our attention. As we all know, hepatitis B virus is the main culprit causing hepatitis, cirrhosis and liver cancer. Why do many people infected with hepatitis B virus do not develop disease and cannot get rid of it? Because there is immune tolerance in human body. In China, mother-to-child vertical infection is the most important way of transmission of hepatitis B virus. The vast majority of carriers are infected from infancy, the development of the infant’s immune system is not perfect, so it does not have the ability to recognize and remove it, so the virus lurks, in the human body’s liver cells to survive, this kind of immunological defects specifically for a pathogen is called immune tolerance. This is when the body’s immune system does not attack the cells where the virus resides, and the two coexist peacefully with each other. Although quantitative HBV-DNA testing suggests active viral replication, liver function is normal and the body has no symptoms. After entering the youth, the immune function of the body of HBV carriers has matured, and it is possible to launch an attack on the cells containing HBV, and the original balance has been broken, at which time the human body is likely to have an attack. Among the HBV carriers, some of them have enhanced immune function and can remove the virus completely, so they heal themselves, and some of them don’t develop disease in their life, while 70%-80% of the carriers may turn into chronic hepatitis after the onset of the disease, and the disease enters into the chronic active phase, which, at this time, brings opportunities for antiviral treatment. HBV carriers with normal liver function do not need treatment. Often there are no symptoms, liver function normal HBV carriers strongly request antiviral treatment, eager to find a complete cure, some indiscriminate medical treatment, deceived in a few. As a doctor must explain to HBV carriers, this condition is not good for treatment. Antiviral treatment is most effective during the active phase of hepatitis, and it is important to master the timing, otherwise it will lead to early onset of the disease. HBV carriers should pay attention to the following matters: regular checkups: although HBV carriers do not have any symptoms, liver function is normal, but still need to pay attention to a regular life, do not overwork. 3-6 months to the regular hospital to check the liver function, the seven indexes and abdominal ultrasound, if there is fatigue, nausea, and other symptoms, you should come to the hospital in time to see a doctor; can not donate blood; cups dedicated to do a separate meal diet, prohibit a large number of alcohol; toothbrushes, utensils, towels alone; delivery and delivery of a child, and the use of towels. Toothbrush, washcloth and towel should be used exclusively; Pay attention to the protection of childbirth and abortion: HBV carriers can get married and give birth to children no matter they are male or female. Mother-to-child transmission is one of the important ways of hepatitis B virus transmission. After delivery, the contents of newborn’s mouth and pharynx should be cleared in time, and the baby should be injected with hepatitis B immunoglobulin and hepatitis B vaccine (according to the requirement of medication) within 24 hours.
