1, the usual contact will be infected: and hepatitis B patients daily contact, such as eating, shaking hands, etc. will not be infected with the hepatitis B virus, and will not be transmitted through breathing. The main route of transmission of hepatitis B is blood transmission. As long as the hepatitis B patient in daily life, toothbrush, razor and other supplies and others separate, women with hepatitis B pay attention to menstrual hygiene, will not be transmitted to others hepatitis B. 2, virus carriers can not get married: Hepatitis B virus carriers can get married, but before marriage each other to test the blood of the hepatitis B antigen antibody system, that is, the “two and a half”. If they are negative, they need to be vaccinated to prevent infection. After marriage, it is important to abstain from sex and avoid drinking alcohol and overexertion. Newborns must be vaccinated against hepatitis B within 24 hours after birth. 3.Adults do not need to be vaccinated: The answer is no. All susceptible hepatitis B patients at high risk of HBV infection should receive hepatitis B vaccine. Mainly include: newborns, infants and preschoolers, medical personnel, close contacts of hepatitis B patients and HBsAg carriers, sexual partners and spouses, newly recruited military personnel, childcare workers, athletes, etc. 4, more liver medicine is better: chronic hepatitis B patients often eat a lot of so-called “liver medicine”, liver health products beyond the scope of the doctor’s recommendations, in fact, is not necessarily beneficial to the liver. Because the amount of medicine is too large, too much variety or too long a course of treatment, only to aggravate the metabolism of the liver, will induce danger. 5, hepatitis B mother can not breastfeed: hepatitis B patients with positive HBsAg in the breast milk, may infect the hepatitis B virus. Now the study concluded that after the implementation of vaccine prophylaxis within 24-48 hours after the birth of the baby, the child can basically avoid contracting the hepatitis B virus through breastfeeding, and breast milk can be fed. But it should be noted: nipples with bleeding and ulcers are not suitable for breastfeeding. 6, “big three yang” than “small three yang” serious condition: big three yang “and” small three yang “are commonly known, the so-called The “big three yang” refers to the patient’s serum hepatitis B marker examination in HBsAg positive, HBeAg positive, anti-HBc positive; “small three yang” refers to the patient’s serum hepatitis B marker examination in HBsAg positive, anti-HBe positive, anti-HBc positive. HBc positive. Clinically, we can understand the presence and replication of hepatitis B virus in the body by testing the hepatitis B markers in the patient’s serum. In the case of “major triple-positive”, the virus is more actively replicating and more infectious than in the case of “minor triple-positive”. However, the severity of the disease (i.e. the degree of liver damage) of hepatitis B patients cannot be determined based on “major and minor triplets”, but mainly depends on the amount of HBV-DNA, the degree of elevated liver function, pathological changes and other indicators. The hepatitis B virus causes damage to human liver cells mainly through complex immune-mediated mechanisms, rather than direct damage to liver cells by the hepatitis B virus. The severity of hepatitis B disease is not directly related to HBeAg positivity or the amount of hepatitis B virus in the blood. A “major triple-positive” person may not have any liver function damage or any clinical manifestations, but only behave as a hepatitis B virus carrier; while a “minor triple-positive” person may be a chronic hepatitis, cirrhosis, or even a heavy hepatitis or liver cancer patient.
