The ALPHA Network (Analysing Longitudinal Population-based HIV/AIDS data on Africa) 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) within PSG.
It aims to:
(i) broaden the evidence base on HIV epidemiology for informing
(ii) strengthen the analytical capacity for HIV research, and
(iii) foster collaboration between network members.
All study sites, some starting in the late 1980s and early 1990s, conduct demographic surveillance in populations that range from approximately 20 to 220 thousand individuals. In addition, they conduct population-based surveys with HIV testing, and verbal autopsy interviews with relatives of deceased residents.
ALPHA network datasets have been used for studying HIV incidence, sexual behaviour and the effects of HIV on mortality, fertility and household and family structure. The activities of the network are centred around workshops, each of which concentrates on a particular analytical theme.
