The ALPHA Network brings together ten population-based HIV surveillance sites in eastern and southern Africa, and is coordinated by the London School of Hygiene & Tropical Medicine (LSHTM).
In recent decades, researchers have developed detailed data sets on various aspects of health in Africa. The network aims to maximise the usefulness of data generated in community-based cohort studies in sub-Saharan Africa for national and international agencies involved in designing or monitoring HIV interventions and epidemiological forecasting.
With funding from the Wellcome Trust the ALPHA network links ten existing HIV cohort studies and runs 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 ALPHA Network is a regular contributor to the UNAIDS Reference Group on Estimates, Modelling and Projections, which oversees the data and methods used for producing HIV estimates for most countries in the world, and to the modelling community through an agreement with the HIV Modelling Consortium.
