Epidemics and pandemics are like earthquakes. Tragic, inevitable and unpredictable. It starts as a random event. A virus jumps species from a bird, bat, or other animal to “Patient Zero” – who passes it on to other human beings. More likely than not, over the course of this century we will face an influenza pandemic similar to the one in 1918 that killed 50m people.

President Barack Obama’s first chief of staff, Rahm Emanuel, said in the wake of the global economic meltdown that “you never let a serious crisis go to waste”. Crises are opportunities to learn. They point to measures that will prevent the collapse of institutions when they are under extreme pressure.

While the focus is understandably on responding to the Ebola crisis, it is equally important that it serves as a wake-up call with respect to inadequacies that threaten not just tragedy on an unprecedented scale but the basic security of the US and other wealthy nations. As with climate change, no part of the world can insulate itself from the consequences of epidemic and pandemic.
