Two Alphacoronavirus strains: HCoV-229E and HCoV-NL63 and five Betacoronaviruses: HCoV-HKU1, HCoV-OC43, SARS-CoV, MERS-CoV, and SARS-CoV-2 have so far been recognized as Human Coronaviruses (HCoVs). Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 is currently the greatest concern for humanity. Despite the overflow of research on SARS-CoV-2 and other HCoVs published every week, existing knowledge in this area is insufficient for the complete understanding of the viruses and the diseases caused by them. This review is based on the analysis of 210 published works, and it attempts to cover the basic biology of coronaviruses, including the genetic characteristics, life cycle, and host-pathogen interaction, pathogenesis, the antiviral drugs, and vaccines against HCoVs, especially focusing on SARS-CoV-2. Furthermore, we will briefly discuss the potential link between extracellular vesicles (EVs) and SARS-CoV-2\/COVID-19 pathophysiology.<\/jats:p>","DOI":"10.3390\/pathogens10091218","type":"journal-article","created":{"date-parts":[[2021,9,21]],"date-time":"2021-09-21T22:34:01Z","timestamp":1632263641000},"page":"1218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Biology and Pathogenesis of SARS-CoV-2: Understandings for Therapeutic Developments against COVID-19"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6692-1898","authenticated-orcid":false,"given":"Homa Nath","family":"Sharma","sequence":"first","affiliation":[{"name":"Microbiology Program, Department of Biological Sciences, Alabama State University, Montgomery, AL 36104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charity O.
