The findings, conducted in the US, Germany, Canada, Spain and France, were presented at the annual meeting of the International Aids Society in Paris.
More than half of people infected with HIV worldwide are now getting drugs, and AIDS-related deaths have nearly halved since 2005, putting the world on track to hit the target of 30 million people on treatment by 2020, the United Nations said last week.
He said there would be a spectrum of children who would be in remission for different periods of time.
Though early anti-retroviral therapy was not standard practice at the time, it was given to the child from nine weeks old as part of a clinical trial. More than 370 infants infected with HIV were randomly assigned to immediately receive ART for either 40 weeks or 96 weeks.
In a child enrolled in a randomized trial of ART interruption this has the first reported case of sustained control of HIV following treatment early in infancy. "We don't really know what is the reason ..."
Fauci said it strengthened the argument that babies born positive must be put on treatment as soon as possible as it stopped the virus entering too many cells.
Research by the US National Institute of Allergy and Infectious Diseases, which sponsored the study, has previously found that early treatment boosts children's survival rates.
Newly-reported cases of Filipinos carrying human immunodeficiency virus (HIV) reached more than a thousand in May, according to the HIV and AIDS Registry of the Philippines (HARP) report. Swaziland's United Nations agency noted that as a result, less than 1,000 children became infected with HIV in the country past year.
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. Tests when she was 9 1/2 years old found signs of virus in a small number of immune system cells, but none capable of reproducing. The child's immune system, however, is healthy and there is no sign of HIV infection and no symptoms.
In fighting off full blown infections after lengthier periods of treatments early in life as two two other children born with HIV one in France and one in MS had shown similar promise.
Beyond that, the team hopes that further research might be able to highlight what it is about the child's physiology that led to such a successful treatment - especially since they don't think early ART by itself can explain the result here. Women with undetectable viral loads have a 0.1 percent chance of passing on the virus to their children.
The U.S. National Institutes of Health is now conducting a trial to test whether giving ART to HIV-infected babies within 48 hours of birth leads to long-term control of the virus after treatment is stopped.
