The exciting results were presented Monday at an HIV/AIDS conference in Paris, known as the International AIDS Society conference.
The South African child is not the first to go into remission after treatment for the virus.
'For these people, getting their HIV treatment through a monthly injection, rather than daily pills, could be life-changing and could mean they are more likely to stay well and to remain uninfectious'.
He said there would be a spectrum of children who would be in remission for different periods of time.
The child has been in remission since eight and half years giving hope to millions of a possible new HIV cure.
In 2007, after he developed leukemia in addition to his HIV, doctors destroyed Brown's immune system with radiation and chemotherapy and replaced it through a bone-marrow transplant from an elite controller.
The child, whose name and gender were not disclosed, was part of a clinical trial in which researchers were investigating the effect of treating HIV-positive babies in the first few weeks of life, and then stopping and starting the ART medicines whilst checking whether their HIV was being controlled. Especially because there were other children in the trial, who received the same early treatment, but didn't have the same outcome.
"We don't really know what's the reason why this child has achieved remission - we believe it's either genetic or immune system-related".
A nine-year-old child has been virtually cured of HIV, scientists claimed yesterday.
Further phase 3 trials of the treatment are already in progress and more evidence will be needed in wider groups of patients but the results from the LATTE-2 study on long-acting therapy could well be the "next revolution in HIV therapy", researchers said.
"Our 9-year old child is adding a little bit more to the picture as one tries to puzzle the complexity of human beings and HIV". It was found that an injection every month or two months was just as effective at preventing the virus from returning as daily pills.
Almost nine years later without additional treatment, the girl has nearly undetectable levels of HIV and no symptoms. They used very sensitive test, and found that a tiny proportion of the child's immune cells contained the virus, but the virus was dormant.
When infected with the HIV virus, humans can not produce the required antibodies to kill it, which is why the HIV vaccine has been a challenge to develop. In 2013, researchers reported the case of a baby born with HIV in MS who was treated with anti-HIV drugs just 30 hours after birth.
The girl, whose identity has been protected, started on medication when she was two months old, and ended the course 40 weeks later, AP reported.
Asean members Malaysia, Indonesia, the Philippines, Vietnam, Myanmar and Thailand are among 10 countries that together accounted for more than 95 per cent of all new HIV infections in the Asia-Pacific region a year ago, according to a new report.
