Strangely enough, I have absolutely no problem with numbers, or for that matter words.
Seen the table. Your point is therefore...
As for ". There will be another plague of Well Nasty going round sometime, very likely in our lifetime", you are possibly correct.
All that this modelling will show is the predicted spread, if nothing is done.
The US would drop the shutters quicker than a cheap prostitute at the sight of a $100 bill.
Affected areas would be quarantined, by force if required.
Not that that would make a great deal of difference if the strain of avian flu involved (as an example) is being carried by migratory birds.
The real question should be why this research is being done by the DHS.
It just smacks of "oh look, *terrorists* could spread biological *weapons* by sneezing on you people. stay afraid"
Or am i just being paranoid?
