The Group for the Scientific Reappraisal of the HIV-AIDS Hypothesis came into existence as a group of signatories of an open letter to the scientific community. The letter (dated June 6, 1991) has been submitted to the editors of Nature, Science, The Lancet and The New England Journal of Medicine. All have refused to publish it. In 1995 The Group was able to get another letter published in Science.

Over the years more and more people have added their signature to the first letter. By signing the letter; the statement below, one becomes a member of The Group too.

It is widely believed by the general public that a retrovirus called HIV causes the group diseases called AIDS. Many biochemical scientists now question this hypothesis. We propose that a thorough reappraisal of the existing evidence for and against this hypothesis be conducted by a suitable independent group. We further propose that critical epidemiological studies be devised and undertaken.
