Peter Daszak has spent the past three decades attempting to predict global pandemics. He leads a group of international investigators who try to anticipate when and where outbreaks will happen and how far they will travel. “Pandemic prediction is a bit like earthquake prediction,” Daszak recently told me from his office in Manhattan. “There are lots of tremors, and occasionally you get a big one. Ebola was the big one.”
