There is a set of people that should definitely have the test.
But at this point, you can’t exclude someone because they weren’t in contact with someone who had just been to China.
For example, you are in a casino in Vegas where a lot of Asian people come and go....you could easily contract it. Well, maybe not easily if you are a causian but if you are an Asian male you better be getting the test.
All I have heard is that the test is available to people with some of the symptoms. In the situation you mentioned, a casino, yes, lots of ways that germs can be spread. If I came down with a fever and cough after this, I would submit to testing, and maybe there will be some case that can be made for these tests to become mandatory rather than simply available.
No one wants the lack of freedom that a major health hazard could impose, but it may happen. I do not know when I would buy in, but I am certain that if the number of cases expands and is out of control with current methods, they perhaps more would be welcomed.
