Scanning electromicrograph of an HIV-infected T cell/NIAID
Almost 37 million people around the world are now infected with human immunodeficiency virus (HIV), the virus that causes AIDS [1]. But many don’t know they are infected or lack access to medical care. Even though major strides have been made in treating the infection, less than half receive antiretroviral therapy (ART) that could prevent full-blown AIDS and reduce the likelihood of the virus being transmitted to other people. Now, a new report restores hope that an end to this very serious public health challenge could be within reach—but that will require a major boost in commitment and resources.
The study conducted by an NIH-funded research team evaluated the costs and expected life-saving returns associated with ambitious goals for HIV testing and treatment, the so-called 90-90-90 program, issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS) in 2014 [2]. The new analysis, based on HIV disease progression and treatment data in South Africa, finds that those goals, though expensive to implement, can be achieved cost-effectively, potentially containing the AIDS epidemic and saving many millions of lives around the globe.
