That reinforces the comment made by Sen. Collins re: sensors in use in 6 other countries to detect ill people. As far as that goes, the Senator is correct. We should take advantage of technology to protect ourselves.
The problem is, as Mr. Barnett stated, for every person coming into the US by air or rail, there are a thousand crossing the border between US Ports of Entry. Those thousand individuals are not screened for anything; there is no way to know whether or not the flu comes across the border in the dead of night...
Exactly - the lady I was sitting next to in the plane was only screened in Mexico City - she had to go considerably out of her way to get to Detroit, but she did it all with any “interference” from the US govt.
