Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
The 2002–2004 outbreak of SARS, caused by severe acute respiratory syndrome coronavirus (SARS-CoV or SARS-CoV-1), infected over 8,000 people from 30 countries and territories, and resulted in at least 774 deaths worldwide. [1] The outbreak was first identified in Foshan, Guangdong, China, in November 2002. [2]
SARS was a relatively rare disease; at the end of the epidemic in June 2003, the incidence was 8,422 cases with a case fatality rate (CFR) of 11%. [5] No cases of SARS-CoV-1 have been reported worldwide since 2004. [6] In December 2019, a second strain of SARS-CoV was identified: SARS-CoV-2. [7]
Bats serve as the main host reservoir species for the SARS-related coronaviruses like SARS-CoV-1 and SARS-CoV-2. The virus has coevolved in the bat host reservoir over a long period of time. [ 17 ] Only recently have strains of SARS-related coronavirus been observed to have evolved into having been able to make the cross-species jump from bats ...
Although no details are yet available, but it is generally believed that MERS-CoV originated from bat coronavirus and specifically suggested to have evolved from the common ancestor of BtCoV-HKU4 and BtCoV-HKU5, under the genus Betacoronavirus. [170] [171] Genetic estimate indicates that SARS-CoV-2 evolved from bat coronavirus in around 1948. [116]
The most closely related bat coronavirus and SARS-CoV diverged in 1986. [81] The ancestors of SARS-CoV first infected leaf-nose bats of the genus Hipposideridae; subsequently, they spread to horseshoe bats in the species Rhinolophidae, then to Asian palm civets, and finally to humans. [82] [83]
As of December 2021, there are five dominant variants of SARS-CoV-2 spreading among global populations: the Alpha variant (B.1.1.7, formerly called the UK variant), first found in London and Kent, the Beta variant (B.1.351, formerly called the South Africa variant), the Gamma variant (P.1, formerly called the Brazil variant), the Delta variant ...
Severe acute respiratory syndrome (SARS) Severe acute respiratory syndrome coronavirus (SARS‑CoV or SARS‑CoV‑1), a strain of severe acute respiratory syndrome–related coronavirus (SARSr‑CoV) 2002 Discovered in Foshan, China. [29] Caused the 2002–2004 SARS outbreak. Possibly originated from horseshoe bats. [30] Humans Common cold
