SARS-CoV-2 invades the human body mainly through the angiotensin-converting enzyme 2 (ACE2) and cofactor transmembrane serine protease 2 (TMPRSS2) receptors in the epithelial cells of the nasopharyngeal tract, and then gradually moves to initiate infection in the lungs, which gradually results in gastrointestinal involvement as well as affects other organs including the heart, kidneys, pancreas, eyes, and skin (Gavriatopoulou et al., 2020; Hoque et al., 2021a; Rahman et al., 2021; Rahman et al., 2021). Here, ACE2 is linked to infection.
