澳抗即澳大利亚抗原,现在称乙型肝炎病毒表面抗原(HBsAg)。澳抗阳性,即HBsAg(+)。它是已受乙型肝炎病毒(HBV)感染的一种血清学标志。人体感染HBV后,不管发病与否,多数人均可通过自身的抵抗力清除这种病毒。但也有部分病人,由于抵抗力较弱,不能清除这种病毒,成为慢性HBsAg携带者,即澳抗阳性。由于澳抗阳性是乙型肝炎病毒(HBV)的外壳蛋白,不会有病毒的核酸成分,所以,就其单纯澳抗阳性者本身而言,不具有传染性,故又称之为无症状HBsAg携带者(ASC)。因此,不能将单纯澳 Australian anti-Australian antigen, now called hepatitis B virus surface antigen (HBsAg). O anti-positive, that HBsAg (+). It is a serological marker that has been infected with Hepatitis B virus (HBV). After human infection with HBV, regardless of the incidence or not, most people can clear the virus through their own resistance. However, some patients, due to their weak immunity, can not clear the virus and become carriers of chronic HBsAg, that is, anti-O positive. As anti-O-positive is hepatitis B virus (HBV) coat protein, there will be no viral nucleic acid composition, so that its pure anti-O positive itself, is not contagious, it is also known as asymptomatic HBsAg carriers (ASC). Therefore, we can not just consider Macao
