现在,我们已有高度敏感的方法来诊断甲型和乙型肝炎病毒感染。使用这些方法的结果,又发现一种变型的急性肝炎,既无甲、乙型病毒可见,又无其免疫指标可测,称之为非甲非乙型肝炎。其病因尚未确定,诊断主要靠排除甲、乙型肝炎的方法。不过,我们已经知道许多关于其流行病学、临床经过和远期预后。 We now have a highly sensitive way to diagnose Hepatitis A and Hepatitis B virus infections. The results of these methods, but also found that a variant of acute hepatitis, both A and B virus visible, but no measurable immune indicators, known as non-A non-B hepatitis.
