An HIV positive man from the UK will be the other person in the story who has been cured for the virus.
Twelve years after the first HIV-positive person was cured, researchers have cured a new HIV patient. For 18 months, the man has been HIV-free without virus-inhibited drugs, writes the New York Times .
The man, who is from London, was diagnosed with HIV in 2003 and began taking medicines in 2012 to control the virus. Four years later, he received a bone marrow transplant to treat cancer. The bone marrow came from a donor who had a gene mutation that was naturally resistant to HIV. The bone marrow changed the man’s immune system, and it was because of the new bone marrow from the correct donor that the man became healthy, the researchers believe.
According to the researchers, about 1 percent of the population originating from northern Europeans and who have inherited a mutation from both parents are immune to most HIV viruses. The donor had this double mutation.
The HIV positive man voluntarily stopped taking HIV medicine to see if the virus returned. Usually, HIV-positive people have to take medicine every day to keep the virus at bay. When stopping the medication, the virus will usually return within two to three weeks. 18 months after stopping the medication, the virus has still not returned.
The research is seen as a milestone in the fight against AIDS. The result was published in Nature magazine Monday and will be presented at an HIV conference in Seattle.
