Infection with SARS-CoV-2 affects multiple organs, as ACE2 is present in large numbers in human lung and small intestine epithelial cells, making the respiratory (Mandal et al., 2021; Stavem et al., 2021) and digestive (Aiyegbusi et al., 2021) systems susceptible to viral attack and disease, and it has also been documented that ACE2 is also expressed in the bile ducts, thus predisposing to liver injury (Hamming et al., 2004; Yang et al., 2020). This evidence concerns the gene ACE2 and infection.
