In this paper, we provide the reach, timing and amount of NPY benefit receipt by interviewing a cohort of 1482 notified adult DS-TB patients sampled from three different groups: general population (529 patients), urban slum dwellers (526 patients) and tea garden residents (427 patients) from four states, Assam, Maharashtra, Tamil Nadu and West Bengal, 16 districts and 118 TB units (one TB unit covers an average 200 000 population). The gene discussed is NPY; the disease is tuberculosis.
