Before revision:  SARS-Cov-2 degrades ACE2 and thus worsens lung injury, causes vasoconstriction, possible thrombotic problemsand exacerbates the inflammatory responsedue to the cross-talk between ACE2, the prothrombotic state and the immune system. I develop here a mathematical model based on the influence of ACE2 on the speed of viral propagation and on the negative effects of its degradation.
