Example Input: Paris (CNN) A 9-year-old South African child diagnosed with HIV when he was 1 month old has been in HIV remission for 8½ years -- without regular treatment. This is the first reported case of a child controlling their HIV infection without drugs in Africa and the third known case globally. Soon after diagnosis, the child was placed on antiretroviral treatment, or ART, for 40 weeks, at which point treatment was stopped and the child's health was monitored. Blood tests in late 2015 revealed the child is in HIV remission, meaning levels of the virus in the blood are undetectable using standard tests. Subsequent testing of samples dating back to the child's infancy confirm remission was achieved soon after treatment was stopped.The 9-year-old has been in HIV remission for most of his lifeUnderstanding his biology may one day help other children come off HIV treatment
