Introduction
India accounts for one-fifth of the global Tuberculosis (TB) incident cases. It is estimated that annually around 330,000 Indians die due to TB.[1] The risk of exposure to Health care workers (HCW) is often overlooked and the hospitals also underplay it. In one of the data published in Lung India 11.2 new cases per 1000 person-years of exposure was reported.[2, 3] It is an important challenge everywhere, particularly in low and low to middle income countries.
