In a new paper about the novel coronavirus published in The New England Journal of Medicine on Wednesday, a team of researchers including those from the Chinese Center for Disease Control and Prevention drew on data from the 425 confirmed cases as of Jan 23, and stated that "there is evidence that human-to-human transmission has occurred among close contacts since the middle of December 2019."
1月29日，包括来自中国疾控中心等机构研究人员在内的一支科研团队在《新英格兰医学期刊》发表的一篇关于新型冠状病毒的新论文称，根据截至2020年1月23日上报的425例确诊病例数据，“相关证据表明，自2019年12月中旬以来，在密切接触者中存在人传人现象。”
The conclusion has led some people to believe that such evidence was already discovered by Chinese researchers in December. They accused researchers and officials with the center of intentionally covering up the risk of transmission among people out of self-interest to gain academic clout.
"The conclusion is a deduction based on a retrospective study that looks back on epidemiology research of infected cases," the center said in a statement, reaffirming that the risk of the virus spreading among people was not discovered at the onset of the outbreak in December.
而论文分析的425例确诊病例在论文撰写前已向社会公布。
The center said that information about the 425 cases analyzed in the paper, including infections of 15 medical workers, was already released to the public before researchers set off the study.
2020年1月29日，中国疾病预防控制中心、湖北省疾病预防控制中心等单位有关专业人员共同在新英格兰杂志发表了题为《新型冠状病毒感染的肺炎在中国武汉的初期传播动力学》的论文，有网友提出质疑。
