Definition : Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin that surfaced in the early 2000s caused by the first-identified strain of the SARS coronavirus (SARS-CoV or SARS-CoV-1).
In late 2017, Chinese scientists traced the virus through the intermediary of civets to cave-dwelling horseshoe bats in Yunnan province. No cases of the first SARS-CoV have been reported worldwide since 2004.
In 2019, a related virus strain, SARS-CoV-2, was discovered. This new strain causes COVID-19, a disease which brought about the ongoing 2019–20 coronavirus disease and coronavirus pneumonia pandemic.
