ویروس هپاتیت c یک ویروس ssrna با پلاریته مثبت است که به خانواده فلاوی ویریده تعلق دارد و به دلیل هتروژنیسیته بالای ژنوم به شش ژنوتیپ اصلی و چندین ساب تایپ طبقه بندی شده است. این ویروس به عنوان مهم ترین عامل هپاتیت های non-a, non-b شناسایی شده و در اکثر افراد مبتلا به سمت مزمن شدن پیش می رود. درصد زیادی از بیماران مزمن نیز به سمت سیروز کبدی و نهایتاً سرطان سلول های کبدی سیر می کنند. از میان عوامل...
