So we will have to act to pre-empt it this time, in Iraq and elsewhere, or it will be too late to resist it at all. For Sept. 11 showed that...

But with most self-limiting viruses, like this one, the virus clears itself out of the bloodstream when the patient recovers. So it's possible the donor was incubating the virus but wasn't manifesting symptoms, and the organ recipients ended up with symptoms because their immune systems were compromised.
