患乙型肝炎的人,他的兄弟姐妹或父母也容易患乙型肝炎,或者成为无症状乙型肝炎表面抗原携带者,这称为家庭集聚现象。人们会问,这是传染还是遗传呢? 患乙型肝炎的孕妇,在分娩过程中,可能把乙型肝炎病毒传染给婴儿,这叫母婴传播,不是遗传。有人认为,常染色体隐性遗传可以造成带毒者的集聚。由于现代遗传免疫学的发展,人们逐渐认识到,人体是否易被肝炎传染上,与人体的免疫功能有着极密切的关系。因此,我们应当了解免疫和遗传的关系。由于种族遗传和个人免疫力的不同,所以,对肝炎的易感性不同,所患肝炎的类型也不同。据调查,移居北美多年的亚洲人所患的乙型肝炎的类型与当地人患的乙型肝炎的类型不一样,而与其祖籍的类型一致。这说明免疫力受着遗传因素的影响。人体感染肝炎病毒后,如果身体里能够产生充足的相应的抗体,就可以将病毒消除;如果相应的抗体不足,病
Hepatitis B, his siblings or parents are also susceptible to hepatitis B, or carriers of asymptomatic hepatitis B surface antigen, which is called familial aggregation. People will ask whether this is contagious or hereditary? Pregnant women suffering from hepatitis B, during labor may be transmitted to the baby hepatitis B virus, called mother-to-child transmission, not genetic. Some people think that autosomal recessive inheritance can cause the accumulation of infected persons. Due to the development of modern genetic immunology, people gradually come to realize that the human body is easily infected by hepatitis and has a very close relationship with the body’s immune function. Therefore, we should understand the relationship between immunity and genetics. Due to the difference between racial inheritance and individual immunity, the type of hepatitis affected is different depending on the susceptibility to hepatitis. According to the survey, Asians migrating to North America for many years suffer from different types of Hepatitis B than the type of Hepatitis B patients in the locality, but are consistent with the type of their ancestral home. This shows that immunity is affected by genetic factors. After the human body is infected with the hepatitis virus, the virus can be eliminated if sufficient antibodies are produced in the body; if the corresponding antibodies are not sufficient, the disease
