  • Eurosurveillance: Real-time tentative assessment of the epidemiological characteristics of novel coronavirus infections in Wuhan, China, as at 22 January 2020

    A novel coronavirus (2019-nCoV) causing severe acute respiratory disease emerged recently in Wuhan, China. Information on reported cases strongly indicates human-to-human spread, and the most recent information is increasingly indicative of sustained human-to-human transmission. While the overall severity profile among cases may change as more mild cases are identified, we estimate a risk of fatality among hospitalised cases at 14% (95% confidence interval: 3.9–32%).

    Note from the editors: novel coronavirus (2019-nCoV)

    At the end of 2019, on 31 December, the World Health Organization (WHO) Country Office in China was informed of cases of pneumonia of unknown aetiology that had been detected in Wuhan, a city in the province of Hubei. Just a day earlier, on 30 December, ProMED-mail published a post calling for more information about ‘A cluster of undiagnosed pneumonia - China (Hubei)’. The post indicated that there had been some 20 patients diagnosed with ‘atypical pneumonia’ with seven of them being severely ill [1]. In their accompanying note, the post’s moderator stated ‘the type of social media activity that is now surrounding this event, is very reminiscent of the original “rumors" that accompanied the SARS-CoV outbreak.’ [Ed. severe acute respiratory syndrome (SARS) coronavirus outbreak in 2003].

    The situation has continued to evolve rapidly since then and just a few weeks later, as at 23 January, 614 laboratory-confirmed cases and 17 deaths have been reported [2] including some cases detected outside mainland China [3]. Meanwhile, on 7 January 2020, the novel coronavirus, currently named 2019-nCoV, was officially announced as the causative agent by Chinese authorities [3]. In order to support public health action, viral genome sequences were released by Chinese researchers on 10 January [4] and 2 days later, four further sequences were also made available on the Global Initiative on Sharing All Influenza Data (GISAID) (https://www.gisaid.org/).
