我国是乙肝的高发区,全国乙肝平均发病率为50/10万[1],人群中乙肝表面抗原(HBsAg)阳性率约10%~15%,乙肝病毒(HBV)感染率60%~70%;慢性HBsAg携带者中,绝大多数同时e抗原(HBeAg)阳性[2],而e抗原阳性具有很强的传染性,因此,控制我国乙肝高流行状态需要2~3代人的共同努力[1]。乙型肝
China is a high incidence of hepatitis B, the average incidence of hepatitis B in the country is 50/10 million [1], the positive rate of hepatitis B surface antigen (HBsAg) is about 10% -15% and the infection rate of hepatitis B virus (HBV) is 60% -70% ; The majority of chronic HBsAg carriers are simultaneously positive for e antigen (HBeAg) [2], while the positive for e antigen is highly contagious. Therefore, controlling the state of hepatitis B in our country requires the joint efforts of two to three generations [ 1]. Hepatitis B
