The Priorities for Local AIDS Control Efforts (PLACE) method aims to improve our understanding of the drivers of local HIV epidemics, identify gaps in services available to those most likely to acquire and transmit HIV, and provide evidence to support tailored interventions to reduce transmission. Achieving this goal is a challenge because many people don’t know they have the virus, making the local pattern of new infections almost impossible to detect.
HIV/AIDS is a leading cause of disease burden in sub-Saharan Africa. Existing evidence has demonstrated that there is substantial local variation in the prevalence of HIV; however, subnational variation has not been investigated at a high spatial resolution across the continent. Here we explore within-country variation at a 5 × 5-km resolution in sub-Saharan Africa by estimating the prevalence of HIV among adults (aged 15–49 years) and the corresponding number of people living with HIV from 2000 to 2017.

Demand for and Uses of Geospatial Mapping in HIV Programs: Documenting the Experiences of End-Users in Mpumalanga Province, South Africa
Geospatial analysis of epidemiological and health service data can generate maps of hotspots—locations where HIV prevalence is concentrated—and existing medical and social services and infrastructure. Using this method of data visualization, program planners can easily determine where HIV resources and services are lacking and where they should be deployed to have the greatest impact.
