When AIDS first emerged in the early 1980s, HIV infection was a death sentence. But a global effort has ensured this is no longer the case for a growing number of people.
The good news today is that the annual number of new global infections continues to fall – from the high point of some 3.4 million in 2001 to 2.3 million in 2012. And, as fewer people contract HIV, and more of those who do are given life-saving treatments, fewer progress to AIDS.
