WASHINGTON (AFP) - Researchers say they have, for the first time, cured a baby born with HIV - a development that could help improve treatment of babies infected at birth. There is an important technical nuance: researchers insist on calling it a “functional cure” rather than a complete cure. That is because the virus is not totally eradicated. Still, its presence is reduced to such a low level that a body can control it without the need for standard drug treatment. The only fully cured AIDS patient recognized worldwide is the so-called “Berlin patient,” American Timothy Brown. He is considered cured of HIV and leukemia five years after receiving bone marrow transplants from a rare donor naturally resistant to HIV.
