How much should you be worried about Ebola?

Yep. Ebola isn’t the one. Flu does a much better job of replicating its DNA.

Horridly, it would be fascinating to see a simulated response to, say, five uncontrolled cases in a major city - i.e. five cases where the victims get medical help quite far down the line, having been in contact with 50 people each.

Would the media imagery have set up a hysterical response that could overload the medical system?

Edit: Ah. and presto: New York hospital treating patient who may have Ebola
