As the HIV epidemic continues to mature alongside the increasing scope and coverage of treatment and prevention programmes, inferring trends in incidence from available prevalence data and subsequently identifying drivers behind epidemic trends will become increasingly complex.25 The availability of prospectively collected programmatic and epidemic surveillance data at a greater sub-national spatial resolution will greatly improve the robustness of future impact evaluations.

In this report, UNAIDS is announcing that 18.2 million people now have access to HIV treatment. The Fast-Track response is working. Increasing treatment coverage is reducing AIDS-related deaths among adults and children. But the life-cycle approach has to include more than just treatment. Tuberculosis (TB) remains among the commonest causes of illness and death among people living with HIV of all ages, causing about one third of AIDS-related deaths in 2015. These deaths could and should have been prevented. Download slide deck

Huge progress has been made since 2000 and millions of lives have been saved. But there are still important milestones to reach, barriers to break and frontiers to cross. The world has agreed to meet a set of global targets by 2020 as part of UNAIDS Fast-Track strategy to end the AIDS epidemic as a public health threat.

Efforts to reach fewer than 500 000 new HIV infections by 2020 are off track. This simple conclusion sits atop a complex and diverse global tapestry. Data from 146 countries show that some have achieved declines in new HIV infections among adults of 50% or more over the last 10 years, while many others have not made measurable progress, and yet others have experienced worrying increases in new HIV infections.
