50 years ago, people with TB (tuberculosis) were quarantined. I know because my cousins husband was confined to a hospital clinic in Nebraska for one year until they determined him free of TB.
Today, people may look at HIV differently but in some cases it becomes full blown AIDS. I watched a pretty young 30 something girl in my community die from AIDS that she contracted from a dirty needle. A needles loss!
The powers that be have more knowledge about these things. Or at least they should have! But this is just my opinion........enough problems have happened in the U.S. by allowing the free entrance of foreigners with problems.
I vote to NOT let anyone tested HIV positive or any other contagious disease into the country.
On the other hand.....if it were someone dear to me, I'd probably feel quite differently. No matter which way I think, there is always a reasonable alternative to how others may think and feel.
I think I'm getting mellow as I age!
