「双语」例行记者会/RegularPressConference（2021-3-31）(39)

追问：我想说明下，关于第三个问题，世卫组织报告中提到要开展第二阶段研究，其中提出了几个步骤，包括进一步研究2019年12月之前可能出现的感染病例。世卫组织总干事昨天在成员国通报会上表示，需得到全面数据，包括始于2019年9月的生物样本。第二阶段研究将何时启动？如果已启动，目前有何进展？
Follow-up: Just to clarify my third question, I was talking about the phase two studies that are recommended in the report from the joint WHO China mission. This is the report that has been endorsed also by the Chinese side. It calls for several further steps, including closer analysis of potential earlier cases from before December 2019. Dr. Tedros again in his meeting with member states yesterday, said that it was necessary to get full access to data, including biological samples from at least September 2019. My question is, when do those phase two studies begin or if they have already begun? What work is already being done?
华春莹：我刚才已经说过，这个事情应该由科学家去做，我没有权利来决定什么时候开始，要不要做。我也想提醒你，世卫组织国际专家组组长安巴雷克在视频新闻发布会上也提到，病毒早期可能在中国以外的地方传播。其他国家发表的研究文献显示可能存在更早期的传播，对这些文献应该加大研究力度。所以联合专家组指出，溯源工作应该基于全球视野，不会局限于某一区域，需要多国多地开展。至于什么时候开始，我们应该把这个任务交给国际专家组，交给世卫组织去开展。不要太过着急，不要想着介入施加影响。这才是应有的正确态度。
