Timothy R. Brown attends a press conference to announce the formation of the Timothy Ray Brown Foundation on July 24, 2012, in Washington, D.C.
Brown, who was known as the "Berlin patient," says doctors have told him he's "cured of AIDS and will remain cured." His case is rare.
Brown had a blood stem cell transplant in 2007 to treat leukemia and his blood donor possessed a rare genetic mutation that provides natural resistance to HIV. Doctors declared him "cured" soon after. He spoke publicly about his experience for the first time in 2012.
Brown died of cancer in September 2020.
