The global HIV epidemic claimed fewer lives in 2015 than at any point in almost two decades, and fewer people became newly infected with HIV than in any year since 1991. The list of countries on the brink of eliminating new HIV infections among children keeps growing. A massive expansion of antiretroviral therapy (ART) has reduced the global number of people dying from HIV-related causes to about 1.1 million in 2015 – 45% fewer than in 2005. UNAIDS/WHO estimates show that more than 18 million people were receiving ART in mid-2016.
