The alternative is spread of a highly contagious and highly lethal disease, potentially to millions. They understand that-thats why they went there in the first place.
Dealing with this isn't enormously complex, lets stop relying on the self-reporting and fundamentally flawed "temp scans" and start getting serious about this disease-the consequences are too serious too ignore.
This is one place where EVERYONE should be conservative, but there are lefties who's own ideology will prevent that.
What is becoming abundantly clear here is that health care workers that treat late stage ebola are most susceptible. The one case in Dallas that involved an infected person out and about in the community when he was contagious resulted in NO transmissions of the virus, even to his family members and girl friend. Experts have said all along that this is an extremely hard disease to convey. That appears to be true.
This is really turning into much to do about nothing. The idea of cutting off travel is actually starting to appear to be not a particularly good idea.
Relax. You are still far more likely to die in a mall shooting or car jacking.
