The global HIV epidemic and the data through which to understand it are continually evolving. Recent developments in HIV estimation tools have been marked by increasing granularity and diversity of data about the epidemic, and the multitude of indicators required to guide the HIV response. This has resulted in a proliferation of specific tools to meet the continually evolving needs for HIV policy in particular settings for particular types of data.

At the same time, the longstanding segmentations of the global HIV epidemic based on epidemiologic profile, types of data, or technical and policy needs are becoming increasingly artificial. Utilisation of these data sources by the UNAIDS-supported models to estimate HIV epidemics is, at present, fragmented across several bespoke tools. This fragmentation forces unsatisfactory decisions between using one data source or another, but frequently not all available data and epidemiologic information holistically to understand and respond to the HIV epidemic.

The programme was divided into the following sessions:

  1. Spectrum updates
  2. Next generation models
  3. Natural history model
  4. Voluntary Male Medical Circumcision
  5. Evidence on age-patterns of incidence and transmission in sub-Saharan Africa
  6. Age patterns of transmission: model based approaches
  7. Harmonising data inputs and codebases for next generation models
