SARSr-CoV

Definition : Severe acute respiratory syndrome-related coronavirus (SARSr-CoV) is a species of coronavirus that infects humans, bats and certain other mammals.[2][3] It is an enveloped positive-sense single-stranded RNA virus that enters its host cell by binding to the ACE2 receptor. It is a member of the genus Betacoronavirus and subgenus Sarbecoronavirus.

Two strains of the virus have caused outbreaks of severe respiratory diseases in humans: SARS-CoV (or SARS-CoV-1), which caused an outbreak of severe acute respiratory syndrome (SARS) between 2002 and 2003, and SARS-CoV-2, which caused the 2019–20 pandemic of coronavirus disease 2019 (COVID-19).[7][8] There are hundreds of other strains of SARSr-CoV, all of which are only known to infect non-human species: bats are a major reservoir of many strains of SARS-related coronaviruses, and several strains have been identified in palm civets, which were likely ancestors of SARS-CoV.[7][9]
