Sounds like we need the national guard on the border yesterday!! Stopping all!!!
What you need to worry about are the special statistics.
If you look at Drudgereport.com today you will notice the headline "1000 cases" and another headline "60 dead".
That's 6 out of 100, or 6%.
Although this is just preliminary, that makes this particular flu more deadly than the Spanish Flu in WWI.
Might as well stop the wind from blowing.
Gonna stop all trucks? Cars? Planes? etc etc.
The way you do a quarantine is you tell them to not cross a line ~ then you get back a ways and if anybody crosses the line you holler at them. If they keep coming toward you they become part of the statistical base. But, this is not black death or cholera so you have to be more restrictive.
