There is no currently known cure for HIV infection or AIDS, according to AVERT. Antiretroviral drugs can suppress HIV symptoms; however, they do not clear the infection completely.
One patient purportedly has been cured of HIV, according to Live Science; however, doctors are not certain what treatment brought about the cure. They believe that the treatment the patient underwent for leukemia in 2007, which included radiation therapy and a bone marrow transplant, affected the cells that are destroyed by HIV. They further theorize that the bone marrow donor possessed a genetic mutation which prevented the virus from reproducing. Two subsequent patients who underwent similar transplants using a different bone marrow donor appeared to be free of the disease initially, but subsequently relapsed.
