HIV/AIDS denialism is the belief, despite conclusive evidence to the contrary, that the human immunodeficiency virus (HIV) does not cause acquired immune deficiency syndrome (AIDS).[1][2][3] Some of its proponents reject the existence of HIV, while others accept that HIV exists but argue that it is a harmless passenger virus and not the cause of AIDS. Insofar as they acknowledge AIDS as a real disease, they attribute it to some combination of sexual behavior, recreational drugs, malnutrition, poor sanitation, haemophilia, or the effects of the medications used to treat HIV infection (antiretrovirals).[4][5]
The scientific consensus is that the evidence showing HIV to be the cause of AIDS is conclusive[1][2] and that HIV/AIDS denialist claims are pseudoscience based on conspiracy theories,[6] faulty reasoning, cherry picking, and misrepresentation of mainly outdated scientific data.[1][2][7] As evidence mounted against denialism, combined with those with HIV/AIDS living much longer, these claims stopped being believed.[8] With the rejection of these arguments by the scientific community, HIV/AIDS denialist material is now targeted at less scientifically sophisticated audiences and spread mainly through the Internet,[9][10] increased substantially since the COVID-19 pandemic.[8]
Despite its lack of scientific acceptance, HIV/AIDS denialism has had a significant political impact, especially in South Africa under the presidency of Thabo Mbeki. Scientists and physicians have raised alarm at the human cost of HIV/AIDS denialism, which discourages HIV-positive people from using proven treatments.[2][9][11][12][13][14] Public health researchers have attributed 330,000 to 340,000 AIDS-related deaths, along with 171,000 other HIV infections and 35,000 infant HIV infections, to the South African government's former embrace of HIV/AIDS denialism.[15][16] The interrupted use of antiretroviral treatments is also a major global concern as it potentially increases the likelihood of the emergence of antiretroviral-resistant strains of the virus.[17]
