一、非甲非乙型肝炎的存在及其研究过程 1975年前后即有人推测有非甲非乙型肝炎(NANB型肝炎)存在。HBsAg检测方法确定后,人们用此法筛选献血员,以期不输用乙型肝炎病毒(HBV)携带者的血液使不再发生输血后肝炎,但实际上输血后肝炎从20％降至10％后却不再下降。因此有人推测尚有经输血传播的非乙型肝炎病毒存在,并命名为丙型肝炎,但当时认为此型病毒不只是一种,因此命名为非甲非乙(NANB)型。其后又证实此种肝炎不只存在于输血后肝炎中,而且于散发性肝炎中也很多。最近日本无乙型
First, the non-A non-B hepatitis and its research process Around 1975, it was speculated that non-A non-B hepatitis (NANB hepatitis) exists. Blood HBsAg detection method is determined, this method is used to screen blood donors in order not to lose the use of hepatitis B virus (HBV) carriers of blood to prevent post-transfusion hepatitis, but in fact the blood transfusion decreased from 20% to 10% After no longer decline. Therefore, it is speculated that there is still blood transfusions of non-hepatitis B virus, and named hepatitis C, but at the time that the virus is not only one, so named non-non-non-B (NANB) type. Later confirmed that the hepatitis is not only present in post-transfusion hepatitis, but also in sporadic hepatitis are also many. No Japanese B type recently
