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 .
Effectively, SARS manages, administers, and implements the tax regime as designed by the Minister and National Treasury. SARS was established in 1997 by a merger of the customs and inland revenue departments, at the recommendation of the Katz Commission, which had been instituted to review the South African tax system for the post-apartheid era.
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
Distinct from the PANGOLIN tool, Pango lineages are regularly, manually curated based on the current globally circulating diversity. A large phylogenetic tree is constructed from an alignment containing publicly available SARS-CoV-2 genomes, and sub-clusters of sequences in this tree are manually examined and cross-referenced against epidemiological information to designate new lineages; these ...
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.
Taxation may involve payments to a minimum of two different levels of government: central government through SARS or to local government. [2] Prior to 2001 the South African tax system was "source-based", where in income is taxed in the country where it originates.
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]
Further analysis of HCoV-NL63 pathogenicity seems warranted, in particular because of recent evidence that this virus uses the same cellular receptor as both SARS-CoV (the causal agent of SARS) and SARS-CoV-2 (the causal agent of COVID-19), [19] the latter of which can provoke a similar immune response.
