SARS coronavirus (SARS-CoV or SARS-CoV-1); Severe acute respiratory syndrome coronavirus


Definition : Severe acute respiratory syndrome coronavirus (SARS-CoV) is the strain of virus that causes severe acute respiratory syndrome (SARS).

It is an enveloped, positive-sense, single-stranded RNA virus which infects the epithelial cells within the lungs. The virus enters the host cell by binding to the ACE2 receptor.

It infects humans, bats, and palm civets.

A pandemic due to novel coronavirus disease in 2019 showed many similarities to the SARS outbreak, and the viral agent was identified as yet another strain of the SARS-related coronavirus, SARS-CoV-2.
