"The world has lost momentum in the fight against the AIDS epidemic, with millions of new people infected last year, the ONE foundation said in a report," titled "The Beginning of the End? Tracking Global Commitments on AIDS" and released on Tuesday, Reuters reports. In its annual report last week, UNAIDS said despite advances in access to medicines that both treat and prevent HIV infection, 2.5 million new cases of HIV occurred in 2011, according to the news service. "That is more than double the target of having only 1.1 million people newly infected each year, said ONE," according to Reuters.
