Cluster of Pneumonia Cases Caused by a Novel Coronavirus, Wuhan, China   [open pdf - 0B]

From the Summary: "As of 17 January 2020, a total of 44 laboratory-confirmed cases infected with 2019-nCoV [2019 novel coronavirus] have been reported, 41 from Wuhan, China and three travel-associated to Thailand (2) and Japan (1). The onset of symptoms ranged from 8 December 2019 to 5 January 2020 and included fever, coughing, and dyspnoea. Chest radiology showed the typical features of a viral pneumonia with diffuse bilateral infiltrates. The majority of cases were males aged 40-69 years. Seven cases developed a severe disease and two with chronic and severe underlying conditions died. Most cases are epidemiologically linked to the specific food market in Wuhan, which was cleaned and closed to the public on 1 January 2020. Some cases reported having visited a different food market while others did not report any link to such environments but had been in contact with people showing respiratory symptoms. So far, none of the reported cases had a disease onset more than 14 days after the closure of the implicated market. Among the cases reported, two small family clusters were identified. In one cluster, all three members of the family had attended the specific Wuhan market before disease onset. In the other cluster, one member was the spouse of a salesman in the market. She developed symptoms after the husband and did not report having visited the market environment before onset of symptoms. There have been no cases reported in healthcare workers, and so there is no evidence of nosocomial transmission so far."
