cd4 count

A friend of mine was recently diagnosed with HIV - I wanted to know more about the HIV virus so I did some research, I have a question which may seem a little silly.

I have read that an AIDS diagnosis is made when the CD4 count drops below 200. I have also read that the viral load can drop down while the CD4 count can shoot up, Does this mean you could be diagnosed with AIDS, and shortly after be diagnosed with HIV again?

No. Once diagnosed with AIDS you always have the AIDS classification. It doesn't matter if your CD4 rise to normal and VL is undetectable. But people like myself don't really care to much with the numbers it's how we feel that matters. You were partially correct about CD4 <200. He is the actual definition of AIDS.
