About AIDS.

Hi Hv,

I'm beginning a study on AIDS (my work partner JUST told me he was diagnosed with it) and read some of your posts here. I have newbie questions though:

What really causes AIDS?
What virus does a PCR count if HIV is a complete hoax?
What cures it?
Could you direct me to some good Pubmed articles or others that would be worth reading to get a good overall knowledge about it?

Thanks,
C.
