Has he done it yet?
Deusberg's offer - or mine if I had ever made such - can't really be taken up because of issues of medical ethics. But nevertheless, I am quite sure Duesberg would be as unconcerned about an HIV infection today as he ever was.
But you must note that Duesberg remains open minded about the ultimate cause of AIDS. He is only very sure that it is not HIV. His fairly high degree of certainty on that point is based on his vast knowledge of retroviruses which at one time was unchallenged and widely heralded, before he refused to "go along" with the HIV-AIDS hypothesis.
