April 30, 2013 Teenagers and adults as old as 65 should get screened for HIV, new guidelines say. People at higher risk of infection, including men who have sex with men and people who use IV drugs, should get retested at least once a year.
March 25, 2013 Condoms have evolved little since latex ones were first manufactured in the 1920s. Bill Gates is hoping to change that. His foundation is giving $100,000 to anyone who can come up with a condom that men or women actually want to wear.
March 15, 2013 French researchers confirm that the immune systems of 14 adults are apparently controlling HIV without medication. It's further evidence that early treatment may prevent the virus from establishing "reservoirs" of HIV-infected cells in the body.
February 28, 2013 Every year about 300,000 babies in sub-Saharan Africa are born with HIV. A new strategy aims to reduce these infections by putting every pregnant woman with HIV on drug treatment for the rest of her life. The approach has worked well, so far, in the small country of Malawi.
February 22, 2013 Treating people for HIV isn't just beneficial for those infected but also helps the entire community. Two studies show that where HIV drugs are widely available, the risk for new HIV infections drops dramatically and overall life expectancy increases by more than a decade.
December 18, 2012 In South Africa, drug users are crushing HIV medications and mixing them with marijuana, heroin and other illicit drugs. Public health workers worry that people who smoke so-called whoonga are helping to fuel the rise of drug-resistant HIV.
November 29, 2012 HIV has been declining in many parts of the world over the past decade. Today the U.S. unveiled an ambitious plan to stop most new HIV infections around the world. But some health leaders question whether their goals are realistic, especially with impending budget cuts.
November 27, 2012 The number of new HIV infections in the U.S. is relatively stable at about 50,000 people a year. But HIV is on the rise in people under 25, federal data show. The upswing is driven largely by infections among young black men.
November 21, 2012 Although new HIV infections have dropped by as much as 50 percent in many African countries, the fight against AIDS seems to be losing its footing in Eastern Europe and parts of Asia. New infections nearly quadrupled in China between 2007 and 2011.
October 22, 2012 Researchers in South Africa tracked how the evolution of the virus in two infected woman shaped the antibodies they produced to fight it. Several months after infection, the researchers saw that the patients had developed more "broadly neutralizing antibodies," which target different versions of the virus.
September 24, 2012 With local hospitals in Durban, South Africa, strained by the AIDS epidemic, city leaders are trying to restore and reopen a historic children's hospital shut down in the 1980s during apartheid. The hospital originally opened in 1931 with a mandate to serve kids of all races.
September 6, 2012 Testing everyone for HIV and then giving them early treatment could theoretically eliminate the epidemic in South Africa. A mathematical model of this "test and treat" strategy suggest that it might be more expensive and take significantly longer than previously predicted.
September 5, 2012 A vaginal ring that releases a drug against HIV shows promise in an animal study as a way to prevent infections. The results bolster hopes that an ongoing clinical trial of a similar ring in people will prove to be successful.
August 21, 2012 Over the past two decades, circumcision rates in the U.S. have fallen to 55 percent from a peak of about 79 percent. A new analysis from Johns Hopkins researchers suggests the decline will add to health care costs.
