But did you think of this angle, if we did stop slowing it down via quarantine,(if it is terrorism) all the terrorists would need to do is release more.
New thoughts I had during dinner, if this were terrorism, whoever is responsible would have to have a "cure". Anything else is far too risky. From what we know of modern science could a terrorist sponsoring state have a cure or vaccine for a complex RNA designer virus (speclation on my part)...That's a big if..
The next argument would be "but they don't care if they die in the process of killing everyone". That is where I say the big guys behind the scenes do. Al Queda, Bin Laden and whoever else is just the hired muscle, IMO.
