COVID-19 occurs when SARS-CoV-2 binds to angiotensin-converting enzyme 2 (ACE2) receptors in airway epithelial cells, resulting in a pro-inflammatory response and acute respiratory distress syndrome.[31] SARS-CoV-2 can exhibit a range of severity, from individuals who show no symptoms to those who suffer from critical conditions such as acute respiratory distress syndrome and failure of multiple organs.[13]. Here, ACE2 is linked to acute respiratory distress syndrome.
