evidence: Two new cases presented Wednesday at the International AIDS Conference in Montreal have advanced the field of HIV cure science, demonstrating yet again that ridding the body of all copies of viable virus is indeed possible, and that prompting lasting viral remission also might be attainable. [...] Over four decades, just five people have been cured or possibly cured of HIV. [...] The first person cured of HIV was the American Timothy Ray Brown, who, like the City of Hope patient, was diagnosed with AML. His case was announced in 2008 and then published in 2009. Two subsequent cases were announced at a conference in 2019, known as the Düsseldorf and London patients, who had AML and Hodgkin lymphoma, respectively. The London patient, Adam Castillejo, went public in 2020.
