It is grim because we don't want to "offend" anyone with the proper response (quarantine the zone) . Political Correctness run amok is going to kill people.
How many dead or sick people before we stop worrying about feelings and sensibilities?
Don't be daft.
It is impossible to quarantine an area encompassing Nigeria, Liberia, Sierra Leone, Senegal, Congo, etc. Furthermore, a quarantine condition would likely lead to a humanitarian disaster, which I'm guessing the US government foresees and wants to establish a presence on the ground to "assist."
As the days go by I can't help but think of the way in which the military was deployed in 28 Weeks Later (sequel to 28 Days). Let's hope treatment production can ramp up and get to the sufferers before a tactical military response is even contemplated.
Also, I suspect one reason why the US is out in front of this is that they've run epidemiological simulations on EBV and have found that the whole world, including the US, in a shitload of trouble in short time.
