Fig. 2From: Lessons learned from the mechanisms of posttraumatic inflammation extrapolated to the inflammatory response in COVID-19: a reviewProposed model of consecutive insult conditions and systemic inflammatory disease progression in COVID-19, based on established trauma modelling. Established concepts in the field of severe trauma and related inflammatory complications have been applied to COVID-19 disease progression. Systemic inflammation may contribute to the restoration of homeostasis and should be considered a physiological process. However, altered inflammatory response may lead to hyperinflammation or a pathological hypo-inflammatory immune response. See text for details and explanations.
