非甲非乙型肝炎又称丙型肝炎,它是由非甲肝病毒、乙肝病毒以及非CMV(巨细胞病毒),EB病毒引起的一种病毒性肝炎。该病原尚未分离成功。有人认为其是GB病毒因子((G.B是一位患肝炎病的外科医师之名)感染,病毒颗粒为20～30毫微米。另有人认为,此病由多种病毒引起,最少有几个亚株,相互无血清学交叉反应。感染途径以血源为主,尤其是输商品血多见。一般散发,发病年龄较高,平均35岁左右。潜伏期介于甲,乙型肝炎潜伏期之间,短者4～6周,长者10～15周,可能与病毒感染量、株型以及机体免疫状态有关。潜伏期短者常出现黄疸,但总的说来非甲非乙型肝炎大多数为无黄疸
Non-A, non-B, also known as Hepatitis C, is a viral hepatitis caused by non-Hepatitis A virus, Hepatitis B virus and non-CMV (Cytomegalovirus), Epstein-Barr virus. The pathogen has not been successfully separated. Some people think that it is GB virus (GB is a surgeon suffering from hepatitis disease) infection, the virus particles 20 to 30 nanometers. Others think that the disease caused by a variety of viruses, at least a few Asian Strains, serological cross-reactivity with each other .Infectious route to blood-based, especially the more common commodity blood loss.General distribution, the incidence of higher age, an average of about 35. The incubation period between A, the incubation period between hepatitis B, Shorter 4 to 6 weeks, the elderly 10 to 15 weeks, may be related to the amount of virus infection, plant type and the immune status of the body .Lip latency is often jaundice, but in general non-A non-Hepatitis B most of the non- jaundice
