An effective response to HIV is a global priority, and sub-Saharan Africa faces the greatest challenge as the region with the largest share of the global HIV burden and the most severe resource constraints.

The ALPHA network brings together ten collaborating African research institutions, which conduct population-based HIV surveillance in eastern and southern Africa, and is coordinated by the London School of Hygiene & Tropical Medicine (LSHTM).

With funding from the Wellcome Trust, the network run analysis workshops to bring diverse data sets into a common format in order to conduct comparative studies and meta-analyses on pooled data sets.

The network regularly contributes detailed statistical estimates of HIV incidence, mortality patterns and fertility impacts to the UNAIDS Reference Group on Estimates, Modelling and Projections, which oversees the data and methods used for producing HIV epidemic updates and projections in African countries.  It also supplies anonymised individual level data to the modelling community through an agreement with the HIV Modelling Consortium.

ALPHA’s investigation of recent HIV mortality change as well as the policy analyses, facility surveys and qualitative studies providing the context to the cohort analyses were funded by the Bill & Melinda Gates Foundation.
