Usually, you'd expect the worst to be the "ground zero" country — in this case, China, then the next wave, which was all in Asia, and then in Europe, and then finally, the U.S. We had all this community spread. With a travel ban, where you actually force people to come back from China, you have to have a way to be able to either just assume they're infected and quarantine them, or test them. And then if they test positive, to have that enforced quarantine. We actually seeded a lot of infection by saying, 'Okay, everybody, residents and citizens come back (and not testing or quarantining).'

This leads to the paradox, that because the disease is only in the poor countries, there is not much investment. For example, there is more money put into baldness drugs, than are put into malaria. Now, baldness, it is a terrible thing [audience laughter] and rich men are afflicted, so that is why that priority is set.

If you show people the problems and you show people the solutions they will be moved to act.
