This amazing man told us that "As awful as this epidemic has been, the next one could be much worse. The world is simply not prepared to deal with a disease — an especially virulent flu, for example — that infects large numbers of people very quickly. Of all the things that could kill 10 million people or more, by far the most likely is an epidemic. But I believe we can prevent such a catastrophe by building a global warning and response system for epidemics. It would apply the kind of planning that goes into national defence — systems for recruiting, training, and equipping health workers; investments in new tools; etc — to the effort to prevent and contain outbreaks."
