Hi all,
Having conducted research on HIV for 8 years in the UK and USA, I really cannot stand idle to listen denialist theories.
There is too much scientific evidence to prove a causative link between HIV infection and the development of AIDS (Acquired Immunodeficiency Syndrome). I suggest people read 'The Band Played On' for an accessible historical perspective on the initial research to identify the causative agent.
Granted, AIDS is a collection of symptoms and manifests rather suddenly without any previous history (hence 'Acquired'). AIDS does not always correlate with HIV infection, as any agent that destroys the immune system can induce a state of AIDS.
The greatest evidence should be from the blood bank cases. People were developing AIDS following transfusions. Once they developed a test to identify the causative HIV
and used it to screen blood donations, they were able to stop transmission. In this illustration, it should be clear that there is a causative link between HIV and AIDS.
Should anyone wish to refute this association of HIV-AIDS, they should ask for a blood transfusion with HIV+ blood.
The human immune system is incredibly complex, and the interplay between viral dynamics and the number and function of immune cells is still so difficult to model. What is certain that an immune system is essential to prevent infection from other organisms that otherwise healthy individuals would not succumb to.
As viruses are dependent on the infected cell to reproduce, the only way to really stop the virus reproducing has been...to stop the human cells reproducing the virus...Most of the early drugs were similar to cancer chemotherapy, being non-specific inhibitors, hence causing a poisoning effect as it kills both the virus, but also some of the body's cells. Without the drugs, individuals may well die sooner.
