What percent of Americans who attract HIV will get the AIDS virus?

Answer 1

The difference between HIV and AIDS is a number.

If you have the HIV virus, and your T-Cell count is below 200, then you are considered (from that point forward, regardless of your T-Cell count) an AIDS patient.

That doesn't mean that everyone with HIV will end up with AIDS... but HIV and AIDS are the same thing; the difference is how much damage the HIV virus has done to your T-Cells.
