Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin caused by the virus SARS-CoV-1, the first identified strain of the SARS-related coronavirus. [3] The first known cases occurred in November 2002, and the syndrome caused the 2002–2004 SARS outbreak .
SARS‑CoV‑2 is a strain of the species Betacoronavirus pandemicum (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. [ 2 ] [ 17 ] There are animal-borne coronavirus strains more closely related to SARS-CoV-2, the most closely known relative being the BANAL-52 bat coronavirus.
In the experiments, macaques infected with the virus developed the same symptoms as human SARS patients. [11] A virus very similar to SARS was discovered in late 2019. This virus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the causative pathogen of COVID-19, the propagation of which started the COVID-19 pandemic. [12]

By 1936, the disease and the virus were recognised as unique from other viral disease. They became known as infectious bronchitis virus (IBV), but later officially renamed as Avian coronavirus . A new brain disease of mice (murine encephalomyelitis ) was discovered in 1947 at Harvard Medical School in Boston.
The researchers found that the virus did not enter human cells as readily as the virus that causes COVID-19 -- which is called SARS-CoV-2 -- writing that the "risk of emergence in human ...
In 2003, following the outbreak of severe acute respiratory syndrome (SARS) which had begun the prior year in Asia, and secondary cases elsewhere in the world, the World Health Organization (WHO) issued a press release stating that a novel coronavirus identified by several laboratories was the causative agent for SARS. The virus was officially ...
Severe Acute Respiratory Syndrome (SARS-CoV-1) The world’s first known coronavirus pandemic occurred in 2002, when SARS-CoV-1 was reported in China. It spread to more than two dozen countries in ...
