非甲非乙型肝炎至少包括有3种病毒对肝脏的感染。这3种病毒或许就是先前所称的“血传播”、“凝血因子传播”和“流行性水传播”的病毒。迄今为止,对3种非甲非乙型肝炎病毒的任何一种,均未建立一个普遍公认的特异性血清学试验。目前非甲非乙型肝炎的诊断仍沿用对已知肝炎病因的血清学排除方法,即排除甲型肝炎病毒(HAV)、乙型肝炎病毒(HBV)、δ肝炎病毒、巨细胞病毒以及 EB 病毒等来确定。所有3种非甲非乙型肝炎病毒引起的有症状感染,在临床表现如黄疸、恶心和深色尿液等方面均相类似,因此病毒间的区别需依靠明显不相同的其他临床和流行病学特征。
Non-A, non-B hepatitis includes at least three types of virus infection of the liver. These three viruses may be what we have previously called “blood transmission,” “clotting factor transmission,” and “epidemic waterborne” viruses. To date, no universally accepted specific serological test has been established for any of the three non-A, non-B hepatitis viruses. At present, the diagnosis of non-A, non-B hepatitis still follows the serological elimination of the known causes of hepatitis, namely, hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus, cytomegalovirus and Epstein-Barr virus To determine. Symptoms of all three non-A non-B hepatitis viruses are similar in clinical manifestations such as jaundice, nausea and dark urine, so the distinction between viruses depends on other clinically and epidemiologically distinct Learn characteristics.
