Signs of HIV have returned in two American men who appeared to have briefly eradicated the virus after bone marrow transplants for cancer, US doctors said Friday. Experts said the discovery is a disappointment to efforts to find a cure for the human immunodeficiency virus behind AIDS, but offers important new clues in the hunt for the disease's elusive hiding places. Only one person is believed to have been cured of HIV. American Timothy Brown, who suffered from leukemia, received a bone marrow transplant from a rare donor who was resistant to HIV, and has shown no sign of the virus for six years.
