When resources are limiting, HIV-control programs need to be geographically selective. Gerberry et al. reached this conclusion after performing a comparative study of strategies for deploying prophylactic antiretroviral drugs in sub-Saharan Africa. The researchers used geospatial modeling to compare programs that would provide equal access to drugs with programs that would maximize the overall societal benefit, two guiding principles created by the World Health Organization for allocating scarce resources. The authors' analysis suggests that the utilitarian principle, which maximizes overall societal benefits by locally distributing drugs to high-incidence areas, trumps access to all.
