I don’t think the concern is about the people who have been identified as having Ebola as much as it is about the possibility that many more may have not yet developed symptoms.
The “concern” is just idiotic panic. Every couple of hours there’s a “possible ebola” case that turns out to be nothing. 2 people, that’s all we’ve got so far, there might be a couple more. But really it’s not worth the ink people are wasting on it, any thoughts of “many” are simple fact deprived foolishness.
