Thankfully? Err..no, quite the opposite. Most countries in the world won't even grant you a long term visa if you have any of a number of communicable diseases, and they don't even have to be incurable. It's a sound policy, which is why it was implemented in the first place. It's unfortunate enough when citizens acquire communicable, incurable diseases which put a strain on the healthcare system and place others at risk, but once they do, there is not much to be done about it aside from trying to contain the risk.
But inviting over
foreigners with HIV, Hep C, etc? Why on god's green earth...
It's all problems and no reward, and doing something that hurts you while providing you with no benefit is one definition of insanity. Coming to America is like trying to get that Derm residency...way more people want it than can get it, which is why Derm doesn't take people who failed their Step the first time, and why America should not take people with huge black marks like serious diseases. Not that picking people who won't spread AIDS among our population is that high a bar to have to clear when selecting immigrants...
