Long considered a contrarian by his scientific colleagues, Duesberg began to gain public notoriety with a March 1987 article in Cancer Research entitled "Retroviruses as Carcinogens and Pathogens: Expectations and Reality". In this and subsequent writings, Duesberg proposed his hypothesis that AIDS is caused by long-term consumption of recreational drugs and/or antiretroviral drugs, and that HIV is a harmless passenger virus. The scientific consensus is that HIV is the causal pathogen that leads to AIDS;
Duesberg's HIV/AIDS claims have been rejected as incorrect and disproven by the scientific community. Reviews of his opinions in Nature and Science asserted that they were unpersuasive and based on selective reading of the literature, and that although Duesberg had a right to a dissenting opinion, his failure to fairly review evidence that HIV causes AIDS meant that his opinion lacked credibility.
Duesberg's views on HIV/AIDS are cited as major influences on South African policy under the administration of Thabo Mbeki. Duesberg served on an advisory panel to Mbeki, convened in 2000. The failure of South Africa to provide antiretroviral drugs in a timely manner, due in part to the influence of AIDS denialism, is thought to be responsible for hundreds of thousands of preventable AIDS deaths and HIV infections. Duesberg disputed these findings in an article in the journal Medical Hypotheses, but the journal's publisher, Elsevier, later retracted the article over accuracy and ethics concerns as well as its rejection during peer review.

The Durban Declaration was drafted and signed by over 5,000 scientists and physicians, describing the evidence that HIV causes AIDS as "clear-cut, exhaustive and unambiguous."
Two independent studies have concluded that the public health policies of Thabo Mbeki's government, shaped in part by Duesberg's writings and advice, were responsible for over 330,000 excess AIDS deaths and many preventable infections, including those of infants.
A 2008 Discover Magazine feature on Duesberg addresses Duesberg's role in anti-HIV drug-preventable deaths in South Africa. Jeanne Linzer interviews prominent HIV/AIDS expert Max Essex, who suggests that, “ ...history will judge Duesberg as either "a nut who is just a tease to the scientific community" or an "enabler to mass murder" for the deaths of many AIDS patients in Africa.
