We aimed to determine whether providing multiple HIV self-tests to pregnant and postpartum women for(More)
BACKGROUND Delivering health services to dense populations is more practical than to dispersed populations, other factors constant. This engenders the hypothesis that population density positively affects coverage rates of health services. This hypothesis has been tested indirectly for some services at a local level, but not at a national level. METHODS(More)
