Outbreak of Acute Respiratory Syndrome Associated with a Novel Coronavirus, Wuhan, China; First Update   [open pdf - 0B]

From the Event Background: "On 31 December 2019, the Wuhan Municipal Health Commission in Wuhan City, Hubei province, China reported a cluster of 27 pneumonia cases of unknown aetiology, including seven severe cases, with a common reported link to Wuhan's Huanan Seafood Wholesale Market (a wholesale fish and live animal market selling different animal species). The cases presented with clinical features common to several infectious respiratory diseases such as fever, dyspnoea, and bilateral lung infiltrates on chest radiographs. Authorities placed all cases under isolation, initiated contact tracing activities and applied hygiene and environmental sanitation activities at the market, which was closed to the public on 1 January 2020. At that time, Chinese authorities reported no significant human-to-human transmission and no cases among healthcare workers. On 9 January 2020, China CDC [Centers for Disease Control and Prevention] reported that a novel coronavirus (2019-nCoV) had been detected as the causative agent for 15 of the 59 pneumonia cases. On 10 January 2020, the first novel coronavirus genome sequence was made publicly available. The sequence was deposited in the GenBank database (accession number MN908947) and was uploaded to the Global Initiative on Sharing all Influenza Data (GISAID). Preliminary analysis showed that the novel coronavirus (2019-nCoV) clusters with the SARS [severe acute respiratory syndrome] -related CoV [coronavirus] clade and differs from the core genome of known bat CoVs."
