Geospatial epidemiology has a long history. Until recently, data limitations meant that intervention policies were designed under an assumption of homogeneous HIV epidemics. But with improvements in data availability and sophistication, it is now well established that the HIV epidemic and its drivers are highly heterogeneous, with studies confirming spatial variation between provinces, districts, and at finer scales in sub-Saharan Africa. Even in generalized HIV epidemics, incidence may be concentrated in certain regions or population groups, such as slums in Kenya, periurban regions of South Africa, and fishing communities in Uganda. Policies that fail to account for such heterogeneity are inherently biased and will leave some places and populations underserved, limiting overall effectiveness and equity.
