HIV has reappeared in the blood of two Boston patients who scientists had hoped had been cured of their infections. The Boston patients have stirred considerable hope among HIV researchers since mid-2012, when scientists cautiously raised the possibility that bone marrow transplants had eliminated the virus from their systems. The only person known to be cured of HIV so far is 47-year-old American Timothy Brown, widely known as the Berlin patient because he received a bone marrow transplant in Germany six years ago. The Boston researchers decided to disclose the news at an AIDS meeting in Florida, because scientists in other institutions had already begun planning experiments to replicate the hoped-for cures in other bone marrow transplant patients infected with HIV.
