Yes, I think it is curable. I have seen people go from HIV+ and sick to HIV- and healthy. The real question though is were they really sick from HIV or was their AIDS due to other causes such as other immune suppressing microbes or their AZT or AZT analogues?
So to prove one way or the other you would have to first prove that the HIV is actually present, which is next to impossible to do. HIV antibody tests are notoriously inaccurate, and PCR (viral load) is nowhere near as accurate as they claim. In fact PCR can neither prove the presence of a particular virus, nor can it show viral activity. It is a sales tool ONLY!!!
This is why I mentioned the AZT. Again AIDS is NOT a disease, it is a syndrome. If you understand the definition of a syndrome then you would also know that this means it can have more than one cause. This includes the primary cause of AIDS in the US, which is AZT, not a virus.
In fact, as a definition of AIDS as a syndrome we can include a host of other microbes as causes of AIDS. These include the PCP bacteria, the KS microbes, the MAC bacterium.....
