The SARS-CoV-2 virus is responsible for the COVID-19 disease pandemic and its main receptor for ECA2 is an octopeptide with vasoconstrictor activity present in host cells, this receptor is key for the entry of SARS-CoV- 2 and it is suggested that it also acts as a limiting factor for viral entry in the initial stage of infection. To carry out this study, a literature search was carried out in Pubmed / Medline, Scopus, Scient Direct and BVS, where review articles and originals were evaluated, in English and Spanish, referring to the study topic through the title. As a result, 153 documents were obtained in PUBMED and 450 in BVS, of which we were left with 70 relevant articles. The conclusion reached was: COVID-19 has 3 clinical stages with a varied immune response, therefore, the treatment of this disease depends on the clinical stage in which the patient is, infectivity in COVID- 19 is related to viral load, the mutations that this virus undergoes help to further strengthen its infective capacity, SARS-CoV-2 binds to ECA2, cell fusion occurs through the union of protein S with the receptor on the surface of the host cell initiating the entire infectious and clinical course of COVID-19, ECA2 is found in the membrane of the epithelial cells of the airways, mostly in type II pneumocytes, they constitute the entry point of the SARS-CoV-2, the expression of ACE and ACE2 in bronchial epithelial cells increased significantly in subjects infected with COVID-19 who suffer from COPD, there are 4 pathophysiological mechanisms associated with ACE2 which, when magnified, produce a greater severity of this disease.
