One of the achievements of the HIV response has been the focus on data to drive an evidence-based response. UNAIDS has led this process through a cycle of agreeing to a set of global targets that countries commit to, adopting those targets in national strategic plans, supporting countries to monitor progress and reporting against those targets to UNAIDS.
UNAIDS data are crucial for the global HIV response as they provide comprehensive, accurate and timely information on the state of the HIV epidemic. These data help countries and organizations understand HIV prevalence, incidence and mortality, and support monitoring of the programmatic response to the epidemic.
