Thrombin levels rise; thrombin converts plasminogen into the active form, plasmin which initiates the fibrinolytic cascade. Fibrinolysis produces high levels of fibrin degradation products (FDPs) which are themselves anticoagulants, promoting further coagulation. As thrombi form in the vasculature, tissues become hypoxic leading to multisystemic organ failure in severe cases.

As [[Thrombocytes|platelets]] are used up in the thrombi, a [[Platelet Abnormalities#Thrombocytopaenia|thrombocytopaenia]] occurs which leads to paradoxical haemorrhaging and the patient starts to shown symptoms of bleeding.  This is the mechanism by which most viral haemorrahgic diseases induce clinical signs.
