Most scholars believe that the formation of asymptomatic hepatitis B virus carriers is mainly related to the body's low immune function; it is also closely related to age, gender and genetic factors.
(1) First of all, mother-to-child transmission: mother-to-child vertical transmission is the most important source of infection for carriers after birth. In the absence of preventive measures, hepatitis B surface antigen, hepatitis B e antigen double-positive mothers, causing mother-to-child hepatitis B virus transmission rate is almost 100%. Infants lack the ability to immunoclear large numbers of invasive hepatitis B virus infections and become "immune-tolerant". The deoxyribonucleic acid of the invading hepatitis B virus can combine with the chromosomal genes of the baby's liver cells, use the baby's liver cells to replicate and multiply, and evade the attack of the body's immune system, thus manifesting itself as a long-term hepatitis B virus carrier state without symptoms.
(2) Infantile infection: young infants such as long-term and hepatitis B surface antigen, hepatitis B e antigen-positive mothers, nannies, relatives close living contact, such as breastfeeding, feeding, kissing and so on can lead to infection; can also be infected through vaccination and injection route. Infancy in a susceptible environment than the adult infection and carry the chance of about 8 times higher.
(3) weaker resistance: immunocompromised or incomplete adolescents and adults exposed to hepatitis B virus, can be manifested as no disease, but can not clear the virus, so that the virus and the organism is in the state of *** survival, and become asymptomatic hepatitis B virus carriers.
China has 120 million hepatitis B virus carriers, such a large social group is collectively shrouded in long-term discrimination, is obviously a major and unavoidable social problems. There are always some people standing in the "public interest" point of view to magnify the contagiousness of hepatitis B and the adverse effects of hepatitis B virus carriers to discriminate against and exclude, many virus carriers in the job, school, marriage and many other aspects of the normal rights and interests are not guaranteed, and even caused them great psychological pressure, so that the deterioration of their condition. The prejudice and arrogance of certain government departments towards hepatitis B carriers makes it even easier to form systematic discrimination that is difficult to rectify. in 2003, Zhou Yichao, a senior student at Zhejiang University, was rejected by the staff of the civil service recruitment office because of his hepatitis B virus, which led to a tragic murder case, highlighting the serious consequences of the infringement of the rights of hepatitis B carriers in an extreme example. To deprive hepatitis B carriers of their right to employment and even education is tantamount to forcing them to the brink of extinction. Fortunately, the Ministry of Personnel and the Ministry of Health issued a new regulation on the admission criteria for hepatitis B carriers, which is regarded by public opinion as a major initiative of the government to respond positively to the rights of hepatitis B carriers, and government departments around the world have opened their doors to hepatitis B carriers, which were once closed.
Like any other disease, hepatitis B carriage should not be a punishment for one person; the disease is the enemy of all mankind***. Our equal exchange with hepatitis B carriers is a process of clarifying misunderstandings and accepting common sense, and moreover, it allows us as a society to move towards a rational path of re-understanding ourselves and advocating tolerance and understanding. As a government, the first and foremost task is to ensure that the public can have access to fairness and justice to the greatest extent possible, and that every citizen can live in a normal and peaceful social atmosphere. For certain special social groups, the government should all the more protect his or her legitimate rights to social assistance and freedom from discrimination. The "Hepatitis Prevention and Education Campaign Launch" led by the Ministry of Health and exemplified by Mr. Andy Lau, a Hepatitis B carrier, is a good way of combining social morality and governmental responsibility.
