From an epidemiological standpoint, wouldn’t it be the height of foolishness to order your expatriates to come home from an infection zone? That is the surest way to get the infection introduced to your population. I should think they would be told to stay in Mexico (or the US) until the storm passes.
Not sure the storm WILL pass.
The best solution would be to bring people home, wearing masks on the planes, and then to isolate them until they have passed the incubation period or until they get the flu and recover.
That would be a real nuisance for those involved, but better than to risk bringing the plague into your country.
I posed this question earlier. Yes.
