LONDON (Reuters) - An HIV-positive man in Britain has become the second known adult worldwide to be cleared of the AIDS virus after he received a bone marrow transplant from an HIV resistant donor, his doctors said.
Almost three years after receiving bone marrow stem cells from a donor with a rare genetic mutation that resists HIV infection — and more than 18 months after coming off antiretroviral drugs — highly sensitive tests still show no trace of the man's previous HIV infection.
