The Perth Group
The Perth Group is a group of HIV/AIDS denialists based in Perth, Western Australia who claim, in opposition to the scientific consensus, that the existence of HIV (Human Immunodeficiency Virus) is not proven, and that AIDS and all the "HIV" phenomena are caused by changes in cellular redox due to the oxidative nature of substances and exposures common to all the AIDS risk groups, and are caused by the cell conditions used in the "culture" and "isolation" of "HIV".
