How long will it be before Al Queda (or whomever) brings ebola into this country and purposefully spreads it everywhere he can? I mean, everywhere, like in diluted vomit spread onto public handrails, etc.
A thousand cases might be enough to shut this country down.
I think a lot less actual Ebola cases. The problem is that the health care system will be overloaded with flu and stomach ailments. They will all have to be isolated and tested. If they get a false positive, then they will chew up an isolation room for a week. If an Ebola case gets a false negative, then he or she will infect others until the Ebola disease becomes unmistakable.
This will happen as soon are there are a few cases that are not "someone who just came from Africa". Imagine you are sent into an isolation section of a hospital with a fever while they wait for the test results. The patients are all separated of course, but do you really think that the health care workers will be able to completely decontaminate in between checking on different patients?
Or they give you an instruction card and send you home. You might be conscientious and do what the card says until the test results come back. But will the actual Ebola cases be that conscientious?
The terrorism threat is frightening. They won't even need to be infected, just obtain infected materials. The scientists know how to preserve ebola viruses and no doubt terrorists will figure it out as well.
