No, he did not get rid of AIDS. There is no cure for AIDS or for HIV, the virus that causes AIDS.
Magic Johnson has been in several magazine ads for a medicine called Combivir. I think it has mislead people into thinking that he no longer has the virus, HIV.
When someone contracts HIV, their body goes through a stage, without medications, in which their T-cells (which are simply a type of white blood cell that helps the body to fight off infection, we all have T-cells) will decrease and their HIV viral load (the amount of HIV virus that is in the blood) will increase. Then that person will be placed on HAART (highly active anti-retroviral therapy) and the T-cells will increase as the viral load decreases (Combivir, the medication that Magic is on is one of the commonly used medications). When the viral load decreases, it usually goes down to a level that is undetectable.
With all that said, the person still has HIV, but doesn't have any detectable virus in their blood. It's still possible to spread the virus, and it's still possible that the virus will again become detectable in the body, hence the reason it's called a retrovirus. It changes and manipulates itself to use the medication in order to make itself stronger and to grow more rapidly.
If this hasn't happened to Magic Johnson, it will one day. No one knows when, not even his doctors. Remember, there is no cure for HIV.
I believe that the magazine ads are misleading the public about Magic. His viral load is undetectable, but he still has the virus in his body, and always will.
