Patient selected Care buddy intervention: In addition to standard of care (above), pre-ART patients randomized to PSCB arm were requested to choose a care buddy who was aware of the patient's HIV infection and resides in the same household or in close proximity. Care buddies attended at least two HIV health education sessions similar to those provided to study participants. Information on HIV, and the importance of adhering to scheduled clinic visits and to prescribed medications were emphasized. Buddies were requested to remind participants to take their prophylactic treatments, and remind them of clinic appointments. No compensation for participation was given to buddies.
