Although hepatitis B is highly contagious, its infection also has certain limitations. Under normal circumstances, the transmission of hepatitis B mainly has the following five aspects: First, mother-to-child transmission. Experts from the Liver Disease Center of Shanxi Datong 322 Hospital pointed out that mother-to-child transmission is the most important route of transmission. About 30% ~ 50% of hepatitis B patients in China are caused by mother-to-child transmission, and more than 90% of adult liver cirrhosis and liver cancer are infected with hepatitis B virus in infancy. As a "three-positive" mother, the probability of children being infected after birth is 90%-95%, and the probability of children born to mothers with negative E antigen is half lower than that of mothers with positive E antigen, about 45%-40%. Second, iatrogenic infection. In the process of hospital examination and treatment, the repeated use of medical devices contaminated by HBV without strict disinfection led to infection. This is called iatrogenic transmission, including surgery, dental instruments, blood collection needles, acupuncture needles and endoscopes. Third, blood transfusion spread. Transfusion of blood and blood products infected by HBV can cause hepatitis B. Fourth, close contact with life. Including cohabitation, as long as the skin and mucosa are damaged, they may be infected. After the skin and mucosa are damaged, if the body fluids of hepatitis B patients fall on your damaged skin and mucosa, they may be infected. Using razors and toothbrushes in daily life can also cause HBV transmission, which is called close life infection. Daily close contact can make blood, saliva, milk and vaginal secretions containing hepatitis B virus enter the susceptible population through tiny scratches and cracks in mucosa or skin, causing hepatitis B virus infection. Fifth, sexual transmission. Sexual transmission is also a kind of body fluid transmission. In addition, kissing can also spread, and it is also possible if the oral mucosa is damaged. In the family, if one spouse is a hepatitis B patient or a hepatitis B virus carrier, the other spouse must be vaccinated with hepatitis B vaccine to obtain antibodies; We should also take various preventive measures in our daily life. In addition to the above five points, ordinary life contact, such as eating together and shaking hands, will not be infected with hepatitis B, and mosquito bites will not be infected. Many people think that mosquitoes will be infected if they suck the blood of hepatitis B patients and then suck their own blood, which is totally unnecessary. If you don't want to be infected with hepatitis B, in fact, the best way is to inject hepatitis B vaccine. If patients are infected with hepatitis B due to delayed injection, they should participate in effective treatment in time. Recommendation of hepatitis B treatment technology-Anti-HBV blood purification therapy "Anti-HBV blood purification therapy" adopts German imported medical ozone high-precision medical therapeutic instrument, adopts the world's most advanced non-glass discharge technology to generate ozone, draws 50- 100ml blood from patients, and adds ozone to patients' blood according to the ratio of 1: 1. Autologous blood reacts quickly after combining with ozone. Induce various cellular components in blood to produce cytokines and active metabolites, and then transfuse oxidized autologous blood to patients themselves, thus triggering a series of immune response reactions, activating neutrophils, enhancing the phagocytosis of granulocytes, penetrating the protein membrane of hepatitis virus, cracking the DNA molecular chain of hepatitis virus, destroying the template of DNA virus replication, activating the immune system of the body, producing various immune cells that kill hepatitis virus, and inducing the body to produce various antiviral cytokines (such as various endogenous interferons and interleukins). Five significant advantages: it is no longer difficult to completely treat hepatitis B, 1, safe, painless and without toxic and side effects: "anti-HBV blood purification therapy" has become the first choice for hepatitis B after years of development and improvement. 2. Avoid drug resistance and protect the liver: The function of "anti-HBV blood purification therapy" is mainly reflected in promoting the oxygen carrying capacity of hemoglobin and improving the oxygen supply of the liver; At the same time, it activates the free radical scavenging system of the liver and improves the antioxidant capacity of the liver. 3. Avoid the disadvantages of traditional drug withdrawal: "anti-HBV blood purification therapy" and its active metabolites induce human body to produce cytotoxic T lymphocytes (CTL) and natural killer cells (NK), and use human body's own immune function to attack and destroy hepatitis virus. It avoids the shortcomings that traditional antiviral drugs, such as lamivudine, are easy to induce virus variation and explosive rebound after drug withdrawal. 4. Solve the pain caused by the side effects of long-term medication: At present, conventional western medicine and traditional Chinese medicine can eliminate or alleviate the inflammation and necrosis of the liver by continuously inhibiting the replication of hepatitis B virus, and delay the progress of the disease, but it is difficult to fundamentally eliminate the virus, so it is easy to relapse after stopping medication. Anti-HBV blood purification therapy uses the body's own immune function to attack and destroy hepatitis virus. 5, the treatment time is short, and the curative effect is good: anti-HBV blood purification therapy improves the oxygen supply to the liver and solves the problem of traditional hepatitis B treatment. Compared with traditional antiviral therapy, the cost is equivalent to many drugs, but the course of treatment is obviously shortened and there are no obvious side effects. Choosing a regular hospital for hepatitis B treatment is more important than treatment. Why is it important to choose a hospital for hepatitis B treatment? Because hepatitis B treatment is a long-term process, it is not recommended to change hospitals and doctors halfway (of course, hospitals and doctors with insufficient qualifications cannot continue to receive treatment). Only the same doctor can fully grasp the progress and prognosis of the disease, and consistency is very important.
