Air China Flight 112 was a scheduled international passenger flight on 15 March 2003 that carried a 72-year-old man infected with severe acute respiratory syndrome (SARS). ). This man would later become the index passenger for the infection of another 20 passengers and two aircraft crew, resulting in the dissemination of SARS north to inner Mongolia and south to Thai
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]
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.
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.
SARS-related coronavirus is a member of the genus Betacoronavirus (group 2) and monotypic of the subgenus Sarbecovirus (subgroup B). [13] Sarbecoviruses, unlike embecoviruses or alphacoronaviruses, have only one papain-like proteinase (PLpro) instead of two in the open reading frame ORF1ab. [14]
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]
The outbreak has revived memories of the SARS virus when the local Chinese officials initially withheld information about the SARS epidemic from the public and later vastly under-reported the number of people that had been infected, downplayed the risks, and failed to provide timely information that experts say could have saved lives.
Travel restrictions reduced the spread of the virus, but because they were first implemented after community spread had established in several countries in distant parts of the world—they produced only a modest reduction in the total number of people infected. Travel restrictions may be most important at the start and end of the pandemic. [3 ...
