【世卫组织：#北京此次应对疫情是很好的例子#】世卫组织卫生紧急项目负责人迈克尔·瑞安称，出现聚集性病例并不意味着第二波疫情。北京此次应对疫情是很好的例子，采取了大规模措施，以防疫情失控，如迅速发现、调查和遏制聚集性传播。Dr Michael Ryan, WHO's top emergencies expert said on Friday that Beijing has done well to control the spread of COVID-19 in light of the recent clusters of COVID-19 cases in China.. Citing the good examples of Germany, Japan and South Korea, Ryan said, "I think our colleagues in Beijing as well are mounting a very large-scale response ... in an attempt to prevent that from getting out of hand," and stressed the importance of rapid detection, investigation and suppression of clusters of cases. Meanwhile, he said there is no specific definition of a second wave and that "having a cluster of cases does not mean a second wave."
