上海交大赵大海做客央视演播室：各国应充分重视新冠奥米克戎新变种
上海交通大学国际与公共事务学院教授、博士生导师，上海交通大学-耶鲁大学卫生政策联合研究中心执行主任赵大海，自新冠肺炎疫情暴发以来，对于新冠疫情暴发、防控以及卫生政策第65次接受央视专访，也是第111次接受央视、上视专访。2021年11月27日，赵大海做客中央电视台英语频道演播室（上海），在《中国24小时》节目，就新冠病毒奥米克戎新变种的相关话题进行了解释和评论。现将访谈内容翻译并摘录如下。
主持人：世界卫生组织已将新冠的新变种命名为奥米克戎(Omicron)，并标注为“一个值得关注的新变异毒株”。该变异病毒已传播到了中国香港。请问我们到底应该如何看待奥米克戎新毒株？
赵大海：尽管奥米克戎新毒株是一个全新的新冠病毒变异体，我们对于该新毒株还了解甚少，然而目前的证据已充分表明：奥米克戎的传播速度比新冠病毒之前的变异体快得多。此外，相关报道已表明，这种新变种比以前的新冠病毒危险得多，因为奥米克戎比以前的新冠病毒有更多的突变。因此，世界各国政府和公众都必须充分重视新冠的奥米克戎新变种。
主持人：正如你所说，我们还没有了解到这种新变异的详细信息，但鉴于早期迹象表明这种变异可能更危险，这将如何影响中国的疫情防控政策？特别是像上海这样刚刚防控住本波疫情的大城市，对坚持“动态清零”的新冠疫情防控政策有怎样的影响？
赵大海：实际上，奥米克戎新变种的出现不会影响中国的新冠疫情防控策略。由于中国防控新冠疫情的策略是保持确诊病例的清零战略，奥米克戎新变种的出现充分证实了中国的病例清零策略是科学的，而且是最好的疫情防控策略。与此同时，新冠新变种的出现也证实了“与病毒共存”策略是不科学的。因此，中国将继续保持新冠病例清零的疫情防控策略。然而，奥米克戎新毒株的出现势必将影响中国防控新冠疫情的总体形势，尤其是对上海这样的大城市而言。中国的大城市比普通城市或其他地区必然要承担更大的疫情防控压力。根据以往新冠疫情抗击的经验，奥米克戎新变种极有可能通过人员或货物的入境而传播到中国大陆，而大城市又是人员和货物入境的最主要通道。因此，各级政府和全国公众，特别是大城市的政府和公众，不能放松警惕，必须高度重视和科学防控潜在的奥米克戎新变种病毒。

Dahai ZHAO Joined CGTN Shanghai Studio: More countries on alert as COVID-19 variant Omicron spreads
Dahai Zhao, a doctoral supervisor at the School of International and Public Affairs of Shanghai Jiao Tong University and Executive Director of Shanghai Jiao Tong University-Yale University Joint Research Center for Health Policy, has been interviewed by CGYN for the 65st time (the 111st time by CGTN / ShanghaiTV) since the COVID-19 pandemic. On November 27, Zhao commented on Academician Zhong Nanshan's opinions on the coronavirus pandemic in the world and China’s zero-Covid strategy on CGTN “Asia Today”.
Anchor: The WHO has labeled this new variant omicron, a variant of concern, apparently it has made its way to China's Hong Kong. Exactly how concerned should we all be?
ZHAO: Although the omicron variant is a brand new variant, we have not known the details of this variant, the current evidence has shown that the omicron variant has much faster spread speed than the previous virus variant. In addition, related reports have demonstrated that, this new variant is much more dangerous than the previous virus, because this new variant has much more mutations than previous virus, therefore the government and the public in all countries in the world must pay attention to the omicron variant.
Anchor: As you say there is still a lot more, we have yet to learn about this new variant, but given early signs that this mutated string, this new string could be more dangerous, um, how will that impact the overall pandemic control in China, which has insisted on a zero case policy?
ZHAO: The appearance of this new variant will not affect China’s combating Covid-19 strategy, because China keeps the zero clearing strategic on combating the Covid-19, their appearance of this new variant has fully confirmed that China's strategy on Covid-19, the zero clearing strategy is scientific and is the best way to control the pandemic. At the same time, this new variant’s appearance has confirmed that the strategy of co-exist with the virus is not scientific. Therefore, China will continue to keep the strategy of zero clearing strategy to control the pandemic. However, the appearance of this new variant will affect China's combating Covid-19 situation, particularly for the big cities such as Shanghai. Because big cities in China have much more burdens than the common cities or other areas. According to the previous experiences of combating with Covid-19, the new variant may be imported to Chinese Mainland through the people or goods from outside of China. Therefore, the government and the public, particularly in big cities, cannot relax the guard and must pay attention to the potential new confirmed cases of the new variant.
