Now, if we had an "undo" button, and we could go back and isolate it and grab it when it first started -- if we could find it early, and we had early detection and early response, and we could put each one of those viruses in jail -- that's the only way to deal with something like a pandemic.
假如我们可以返回，并且在这个病毒一出现的时候就抓到它 假如我们可以很轻松的发现这个病毒 并且早发现早反应 我们就能将这些病毒放到“监狱”了 这是我们应对大流感的唯一办法
