於2014 年，全世界避免了一場恐怖的伊波拉疫情大爆發，這要感謝成千上萬無私的衛生人員—但坦白說，還要加上運氣好。事後諸葛，我們知道我們真的應該做得更好。所以，比爾蓋茲提議現在就是時候要把好想法付諸實踐，從沙盤推演、疫苗研究到衛生人員訓練。正如他所說：「我們不需要恐慌，但是一定要開始行動。」

下一場疫情爆發怎麼辦？我們還沒預備好！

The most serious danger to humanity is no longer nuclear war, but a fast-moving infectious disease. A future epidemic could kill over ten million people if the world remains unprepared. The Ebola outbreak showed how missing systems, slow responses, and sheer luck kept catastrophe at bay. Building rapid-response teams, improving health infrastructure, and running 'germ games' can help safeguard everyone before disaster strikes.
