Covid-19 is the disease caused by the SARS-CoV-2 virus. From [0]: > Through DivErsity pArtitioning by hieRarchical Clustering-based analyses,5 the newly emerged coronavirus was deemed not sufficiently novel but is a sister virus to SARS-CoV, the primary viral isolate defining the species. The SARS-CoV species includes viruses such as SARS-CoV, SARS-CoV_PC4-227, and SARSr-CoV-btKY72. SARS-CoV-2 is the newest member of this viral species. The use of SARS in naming SARS-CoV-2 does not derive from the name of the SARS disease but is a natural extension of the taxonomic practice for viruses in the SARS species. The use of SARS for viruses in this species mainly refers to their taxonomic relationship to the founding virus of this species, SARS-CoV. In other words, viruses in this species can be named SARS regardless of whether or not they cause SARS-like diseases.
