SARS coronavirus
The SARS coronavirus, sometimes shortened to SARS-CoV, is the virus that causes severe acute respiratory syndrome (SARS). On April 16, 2003, following the outbreak of SARS in Asia and secondary cases elsewhere in the world, the World Health Organization (WHO) issued a press release stating that the coronavirus identified by a number of laboratories was the official cause of SARS. Samples of the virus are being held in laboratories in New York, San Francisco, Manila, Hong Kong, and Toronto.
On April 12, 2003, scientists working at the Michael Smith Genome Sciences Centre in Vancouver, British Columbia finished mapping the genetic sequence of a coronavirus believed to be linked to SARS. The team was led by Dr. Marco Marra and worked in collaboration with the British Columbia Centre for Disease Control and the National Microbiology Laboratory in Winnipeg, Manitoba, using samples from infected patients in Toronto. The map, hailed by the WHO as an important step forward in fighting SARS, is shared with scientists worldwide via the GSC website (see below). Dr. Donald Low of Mount Sinai Hospital in Toronto described the discovery as having been made with "unprecedented speed."〔(【引用サイトリンク】date=April 2003 )〕 The sequence of the SARS coronavirus has since been confirmed by other independent groups.
==SARS==
(詳細はSevere Acute Respiratory Syndrome, is the disease caused by SARS coronavirus. It causes an often severe illness marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms,〔 mainly cough, dyspnea, and pneumonia. Another common finding in SARS patients is a decrease in the number of lymphocytes circulating in the blood.
In the SARS outbreak of 2003, about 9% of patients with confirmed SARS infection died. The mortality rate was much higher for those over 50 years old, with mortality rates approaching 50% for this subset of patients.〔
