4月27日世界權威科學雜誌 Nature 刊出文章，稱對於有效遏止COVID-19疫症，香港教了全球一課，文章附圖顯示香港在避免死亡方面，遠勝發達大國，情況簡宜是平行時空。
我們香港二月初就已經把傳染率（R）壓低到臨界值 " 1 " 的水平，科學家注意到香港用了三招：
- 迅速的監測
- 適當的檢疫
- 全民保持社交距離（口罩、停課等）
香港人高度自律，在保持社交距離一項做到近乎完美，為我們自己喝采。
“Hong Kong seems to have given the world a lesson in how to effectively curb COVID-19. With a population of 7.5 million, it has reported just 4 deaths. Researchers studying Hong Kong’s approach have already found that swift surveillance, quarantine and social-distancing measures, such as the use of face masks and school closures, helped to cut coronavirus transmission — measured by the average number of people each infected person infects, or R — to close to the critical level of 1 by early February.”
