Fifth person cured of HIV pictured.

Paul Edmonds, a 67-year-old man from California, has become the fifth person ever to be cured of HIV. He was diagnosed with AIDS in 1988 and was cured using a rare but risky blood stem cell transplant from a person with a blood mutation that makes them resistant to HIV. The transplant can often result in deadly infection. Because of this, it is reserved for people like Mr Edmonds who are suffering from late-stage cancer. The first man to successfully receive this treatment was Timothy Ray Brown - dubbed the 'Berlin patient' - whose bone marrow transplant in 2007 rid his body of the virus.
