Background: Door-to-door distribution of HIV self-testing kits (HIVST) has the potential to increase uptake of HIV testing services (HTS). However, very few studies have explored the social response to and implications of door-to-door including secondary distribution of HIVST on household relations and the ability of individuals to self-test with or without supervision within households.
Methods: A CRT of HIVST distribution was nested within the HPTN 071 (PopART) trial, in four Zambian communities randomised to receive the PopART intervention.
