Editing Duesberg hypothesis (section)

==Duesberg claims that retroviruses like HIV must be harmless to survive==
Duesberg argues that [[retroviruses]] like HIV must be harmless to survive: they do not kill cells and they do not cause cancer, he maintains. Duesberg writes, "retroviruses do not kill cells because they depend on viable cells for the replication of their RNA from viral DNA integrated into cellular DNA."<ref name="DuesbergJBiosci"/> Duesberg elsewhere states that "the typical virus reproduces by entering a living cell and commandeering the cell's resources in order to make new virus particles, a process that ends with the disintegration of the dead cell."<ref>[Duesberg P "Inventing the AIDS Virus" Regnery, 1997. {{ISBN|0-89526-399-8}}] Page 90.</ref>

Duesberg also rejects the involvement of retroviruses and other viruses in [[cancer]]. To him, virus-associated cancers are "freak accidents of nature" that do not warrant research programs such as the [[war on cancer]]. Duesberg rejects a role in cancer for numerous viruses, including [[leukemia]] viruses, [[Epstein–Barr virus]], [[human papilloma virus]], [[hepatitis B]], [[feline leukemia virus]], and [[human T-lymphotropic virus]].<ref name="inventing">Duesberg P "Inventing the AIDS Virus" Regnery, 1997. {{ISBN|0-89526-399-8}}</ref>

Duesberg claims that the supposedly innocuous nature of all retroviruses is supported by what he considers to be their normal mode of proliferation: infection from mother to child ''in utero''. Duesberg does not suggest that HIV is an [[endogenous retrovirus]], a virus integrated into the [[germline]] and genetically heritable:
