You will understand what I mean as Obola lets 150 random ebola land people into the country each day. Those are the people who should be kept out or quarantened, not a handful of HCWs. When those Liberians or whatever get out and die on the street as a bleeding mess then a bunch of people will die from that (e.g. first responders).
I wonder how much our sanitized environment, clean water, immunizations, etc, will impact the spread of a disease like that here one way or the other. In other words, are our immune systems more likely or less likely to resist this thing.
