This is amazing, given that it has been only 30 years since AIDS first started to have global repercussions, and given how very little we knew about viruses in the early 80′s:
We are at a moment of extraordinary optimism in the response to the human immunodeficiency virus (HIV). A series of scientific breakthroughs, including several trials showing the partial efficacy of oral and topical chemoprophylaxis1,2 and the first evidence of efficacy for an HIV vaccine candidate,3 have the potential to markedly expand the available preventive tools. There is evidence of the first cure of an HIV-infected person. And most important, the finding that early initiation of antiretroviral therapy can both improve individual patient outcomes and reduce the risk of HIV transmission to sexual partners by 96%4 has led many to assert what had so long seemed impossible: that control of the HIV pandemic may be achievable.
