The virus&#44; in relation to the lungs&#44; activates innate immunity&#44; resulting in an inflammatory cytokine release cascade&#44; including interleukin 6 &#40;IL-6&#41;&#44; IL-1&#44; tumour necrosis factor alpha&#44;

Another mechanism that may be involved is the hypercoagulability state associated with SARS-CoV-2 infection &#40;thromboinflammatory state&#41;&#44; responsible for the disproportionately high &#40;20-30&#37;&#41;
