Life-threatening clots within the arteries of the lung, generally known as pulmonary emboli, might happen even after signs of the an infection have resolved. Damaged blood vessels might change into leaky and vulnerable to bleeding. In youngsters, irritation of veins and arteries triggered by extreme immune activation might trigger an sickness just like Kawasaki illness, an inflammatory dysfunction.

Brain — dysfunction within the lining of blood vessels and related bleeding and clotting issues might trigger strokes and bleeding within the mind. Patients may additionally expertise headache, dizziness, confusion, impaired consciousness, poor motor management, delirium and hallucinations.
