疫病、战争、饥荒被称为人类悲剧的“三剑客”。

The plague, war, and famine are called the tragic Three Swordwarsin the history of mankind.

我很关心这样的事实，即当我们认识到看待这些感染的一种潜在的新方法时却又免不了这些真实的人类悲剧。

I am quite concerned that we be sensitive to these true human tragedies while recognizing the potential of a new way to view these infections .
