A groundbreaking new study has shown that HIV infected partners are much less likely to pass on the virus to uninfected partners if they are put on antiviral treatment sooner, rather than later-on in their infection. The study is being hailed as perhaps the most significant breakthrough in HIV prevention to date.
The study results were not entirely unexpected. Previous “test and treat” studies have already shown that when an HIV infected individual is diagnosed and put on treatment they are less infectious. What's significant is the new study is the first major clinical trial to show how best to make that work.
