Population-Based HIV Surveillance
The longitudinal, dynamic cohort was established in South Africa in 2003 and includes the resident adults aged 15 and above living in the demographic surveillance area. The cohort is one of Africa’s largest and 75% of HIV negative individuals re-test. The spatial distribution of HIV prevalence within this cohort varies with the highest HIV prevalence being observed along the national road (>35%) and the lowest HIV prevalence (<10%) being observed in the rural hinterland of the surveillance area.
88,600 samples have been collected over the past 13 years; 25% of these are samples are of HIV positive individuals and some of these samples will be analyzed as part of PANGEA_HIV.
