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 symptoms.
