Editing Duesberg hypothesis (section)

==Current AIDS definitions==
Duesberg argued in 1989 that a significant number of AIDS victims had died without proof of HIV infection.<ref>{{cite journal |author=Duesberg P |title=Human immunodeficiency virus and acquired immunodeficiency syndrome: correlation but not causation |journal=Proc Natl Acad Sci USA |volume=86 |issue=3 |pages=755–64 |year=1989 |pmid=2644642 |doi=10.1073/pnas.86.3.755 |pmc=286556|bibcode = 1989PNAS...86..755D |doi-access=free }}</ref> However, with the use of modern culture techniques and [[polymerase chain reaction]] testing, HIV can be demonstrated in virtually all patients with AIDS.<ref name="niaid"/> Since AIDS is now defined partially by the presence of HIV, Duesberg claims it is impossible by definition to offer evidence that AIDS does not require HIV. However, the first definitions of AIDS mentioned no cause and the first AIDS diagnoses were made before HIV was discovered. The addition of HIV positivity to surveillance criteria as an absolutely necessary condition for case reporting occurred only in 1993, after a scientific consensus was established that HIV caused AIDS.<ref>[Centers for Disease Control and Prevention, ''Morbidity and Mortality Weekly Report,'' 31(37), 24 Sep 1982] ''Update on Acquired Immunodeficiency Syndrome (AIDS), United States.''</ref><ref>[Centers for Disease Control and Prevention, ''Morbidity and Mortality Weekly Report,'' 34(25), 28 June 1985] ''Revision of the CDC Surveillance Case Definition of Acquired Immunodeficiency Syndrome for National Reporting, United States.''</ref><ref>[Centers for Disease Control and Prevention, ''Morbidity and Mortality Weekly Report,'' 36(S1), 14 August 1987] ''Revision of the CDC Surveillance Case Definition for Acquired Immunodeficiency Syndrome.''</ref><ref>[Centers for Disease Control and Prevention, ''Morbidity and Mortality Weekly Report,'' 41(RR-17), 18 December 1992] ''1993 Revised Classification System for HIV Infection and Expanded Surveillance Definition for AIDS Among Adolescents and Adults.''</ref>
