人类ABO血型是由遗传因素决定的,同时ABO血型能影响人体对某些疾病的易感性。目前乙型肝炎发病率高,传染性强,流行面广,已经构成社会公共卫生的严重问题,全国正在组织科研人员进行重点攻关。国内外在研究乙型肝炎中均发现乙型肝炎表面抗原(HBsAg)阳性者呈家庭聚集现象。其原因还不甚清楚,也可能与基因遗传有关。如果HBsAg与ABO血型有易感关系,又 Human ABO blood group is determined by genetic factors, while ABO blood group can affect the body’s susceptibility to certain diseases. At present, the high incidence of hepatitis B, highly contagious and widespread epidemics have posed a serious problem of social public health. The whole country is organizing research personnel to conduct key research. At home and abroad in the study of hepatitis B were found in hepatitis B surface antigen (HBsAg) positive family aggregation phenomenon. The reason is not clear, it may be related to genetic genetics. If HBsAg and ABO blood type are susceptible, again
