The impact of the unclean and crowded living conditions, especially that experienced in the thickly populated slums of the developing countries, towards enhancing the risk of tuberculosis (TB) infection is well known, and the same has been documented previously [1-3]. Historically, TB has been a disease associated with poor people across the world. On an average about 2–3 million people succumb to this neglected yet a lethal disease. Of this population, a large fraction belongs to the underprivileged habitats in the developing countries and the poor, urban neighbourhoods in wealthier, advanced powers [1].
