以止血受损为主要特征的病毒感染常有血小板减少性紫癜及弥漫性血管内凝血(DIC)。出血机理涉及免疫病理与严重的疾病,暴发性肝炎中肝细胞损害所致的凝血因子形成减少及调节止血的肝功能受损也与出血有关。出血热病毒常致出血,但其致病与出血机理尚待研究。在出血性病毒感染中首需使用抗病毒药物,但目前尚缺有效制剂。
In order to stop bleeding is the main characteristic of viral infection often have thrombocytopenic purpura and disseminated intravascular coagulation (DIC). Bleeding mechanism involves immunopathology and severe diseases, fulminant hepatitis, liver cell damage caused by reduced formation of clotting factor and regulation of hemostatic liver function damage is also associated with bleeding. Hemorrhagic fever virus often causes bleeding, but its pathogenesis and bleeding mechanism remains to be studied. In the first hemorrhagic virus infection antiviral drugs, but there is no effective preparation.
