The new UNAIDS report highlights both the enormous gains already made and what can be achieved in the coming years through a fast-track approach. In just the last two years the number of people living with HIV on antiretroviral therapy has increased by about a third, reaching 17.0 million people—2 million more than the 15 million by 2015 target set by the United Nations General Assembly in 2011. This accounts to 46% of all people who need ART, with additional 2 million people starting treatment during last year. However, huge challenges lie ahead. In 2015 there were 2.1 million [1.8 million–2.4 million] new HIV infections worldwide, adding up to a total of 36.7 million [34.0 million–39.8 million] people living with HIV.
