A 42 year old man being treated for leukemia appears to have been cured of aids. After undergoing a bone marrow transplant from a donor that has a genetic mutation that renders the patient immune, the recipient now also appears to be aids free. It has been over 600 days since the transplant and over 285 days since being removed off all drugs and the virus is still not being detected.
