You can’t be serious. Mexico is where this started....
Apparently you don’t know anything about illnesses. You quarantine the source...
It's in NYC. Quarantine?
You could recall every American servicemen from over seas and activate the entire reserve and guard and put them on the border and nothing will change.
This thing has a several day incubation period. Any American who has been to Mexico in the past 7-10 days is potentially infected and has probably already infected numerous people who are infecting numerous people and so forth.
The whole notion of quarantining a pandemic these days is nothing but a feel good idea the Government put’s out to give the impression that they are in control and can control it.
In the day and age of mass global travel and commerce, you just can’t isolate these things.
