    Epidemiologic characteristics of early cases with 2019 novel coronavirus (2019-nCoV) disease in Republic of Korea

    Abstract

    Since the first case of 2019 novel coronavirus (2019-nCoV) in South Korea was confirmed on January 20, 2020, there have been 24 confirmed cases of 2019-nCoV. The majority of these cases (58.3%; n=14) were male, with a median age of 42 years (range, 21-62 years). Of the confirmed cases, 15 were index cases (63%), six were first-generation patients (24%), and three were second-generation patients (12.5%). All the first- and second-generation patients were family members or close acquaintances of index cases. All the index cases entered the South Korea from January 19 to 24, 2020. The average incubation period was 3.6 days (median, 4 days) and the reproduction number (R0) was calculated as 0.5. Two of the confirmed cases were asymptomatic. As of February 8, 22 patients with 2019-nCoV are hospitalized in South Korea, and 2 have been discharged from the hospital. The epidemiological indicators will be revised as new information becomes available in the future. Sharing epidemiological information among researchers around the world is essential for efficient preparations and responses to new infectious diseases.

Abstract Background: A recent cluster of pneumonia cases in Wuhan (China) is known to be caused by a novel beta-coronavirus named the 2019 novel coronavirus (2019-nCoV) and can be spread through human-to-human transmission. In this study, we reported the epidemiologic and clinical features of suspected and confirmed cases of imported 2019-nCoV in North Shanghai, China. Methods: Data of 21 patients with laboratory-confirmed 2019-nCoV and 84 patients with suspected 2019-nCoV were analyzed by RT-PCR. The epidemiologic and clinical features as well as clinical outcomes were compared between the confirmed and suspected cases.

    • Estimating the Number of 2019 Novel Coronavirus Cases in Chinese Mainland 15 Pages Posted: 4 Feb 2020 Huwen Wang Shanghai Jiao Tong University (SJTU) - School of Public Health Zezhou Wang Fudan University - Department of Oncology More... Abstract Background: An outbreak of clusters of viral pneumonia due to 2019 novel Coronavirus (2019-nCoV) happened in Wuhan, Hubei province in China in December 2019. Since the outbreak, 2 studies estimated the possible epidemic trend of the infection, but proved to be inconsistent with the actual confirmed number of cases. We intend to re-estimate the trend and peak arrival time for the 2019-nCoV infection transmission in Chinese mainland using the SEIR model, so as to provide theoretical basis for future prevention and control of the current epidemic in China. Methods: An infectious disease dynamics SEIR model was applied to forecast the epidemic’s development trend in China from 26 January 2020 based on data collected from the database reported by the National Health Commission. R0 were assumed to be 0.5, 0.25 and 0.125. Findings: The estimated numbers of cumulative cases would reach the peak on 3rd, 4th and 5th of February, 2020, which were 11,116, 11,373, 11,966, respectively, in Chinese Mainland. Similar peaks were also identified in Hubei Province, Wuhan City and other locations of China outside Hubei Province. The epidemic of 2019 novel Coronavirus was estimated to subside between early May (R0 = 0.125) and early August (R0 = 0.5). The estimated average number of deaths ranged from 344 to 1146. *注，本文为预印本论文手稿，是未经同行评审的初步报告，其观点仅供科研同行交流，并不是结论性内容，请使用者谨慎使用.
