  1. a Number of smear positive index cases in the household in the preceding 3 months, b crowding index at night was obtained by number of all persons sleeping in the house divided by the number of rooms in the house, c malnutrition was present in those with any weight faltering on their growth charts and those who had under-nutrition <80%, d TB suggestive symptoms included those with cough ≥2 weeks, fever ≥2 weeks, weight loss, fatigue, reduced play, or any swellings. e statistically significant factors.
