Human-to-Human Transmission
After the disclosure of "pneumonia caused by unknown reasons" by Wuhan Municipal Health Commission on December 31, 2019, there had been no clear answer to whether the virus could be transmitted from human to human until January 20, 2020. On that day Academician Zhong Nanshan, who heads China's COVID-19 Expert Team and the High-level Expert Group of the NHC, made it clear in an interview that there was a phenomenon of human-to-human transmission for the novel coronavirus. This scientific judgment has given the public a deeper and clearer understanding of the disease. Since then, strict prevention and control measures have been enforced throughout the country.
On January 21, the WHO stated that the latest reported infection information suggested persistent human-to-human transmission. In an interview on February 18, Zhong Nanshan pointed out that to effectively stop human-to-human transmission of the virus, there must be separation of healthy people from the infected, and separation of COVID-19 patients from flu patients.
人传人
自2019年12月31日“不明原因肺炎”由武汉卫生健康委公开披露以来，病毒是否人传人一直没有明确答案。2020年1月20日，新冠肺炎疫情科研攻关专家组组长、国家卫生健康委高级别专家组组长钟南山院士在接受采访时明确表示，此次新冠肺炎存在人传人的现象。这一科学判断让大众对于新冠肺炎疫情有了更深刻、更清晰的认知。自此，全国各地开始采取严格的防控措施。1月21日，世界卫生组织称，最新报告的感染信息表明，可能存在持续人传人。2月18日，钟南山院士在接受采访时提出，为有效阻止病毒人传人，迫切需要解决两个问题：一是正常人和病人分开，二是新冠肺炎病人和流感病人分开。
