Amongthe 474 subjects, 75 (16%) had attended the group counselling cum medical camp after completion of baselinesurvey in the intervention group, Among the remaining subjects (n=399), 88% were contacted through FTF andmobile phone (8.5%). In the second session (4-6 weeks time period), the response rate for individual counsellingwas 94% (78% through FTF and 16% through mobile phone). At 3 months, 70.4% were contacted by theirmobile phone and further, 19.6% through FTF (total 90%) while at 6 months (fourth session), the response ratewas 74% and 16.4% for FTF and mobile phone respectively, covering 90.4% of the total subjects.
