Background statement: The global "90-90-90" targets introduced by UNAIDS in 2014-90% of people living with HIV will know their HIV status; 90% of those will be on antiretroviral treatment; and 90% of those will achieve viral suppression by 2020-have become more than a useful heuristic device, and now are the predominant framework for monitoring progress in the HIV response. Although this allows for important reflection on where HIV treatment gaps and opportunities exist in any particular context and globally, it deflects attention away from other very important aspects of HIV epidemics and their often-disproportionate impact on specific populations. Most significantly, it begs the question, what about the other 10-10-10?
Approach: This article takes a critical look at the 90-90-90 targets and what is known about the 10-10-10 left behind to highlight some core issues and attendant questions that should be prioritized if we really intend to "get to zero."
Findings and conclusions: These issues include how the targets are measured in the first place, the limitations of focusing the global response only on antiretroviral treatment and only on people already living with HIV, and the need for more, basic social research to address the range of factors underlying disparities in who are and are not reached in the 90-90-90 framework.
