A survey of the stations of the TB welfare service revealed that of 250 patients who received less than 6 month of in-patient treatment, at least 52.9.percent had negative sputum. In a study carried out during the year 1965-66, 92 patients admitted with positive sputum findings were dealt with ; during that period 60-100 beds on average were available for male patients with open pulmonary TB. In all these cases the diagnosis had been arrived at accidentally; the patients were or claimed to be asymptomatic. One quarter of these patients were homeless and most came from the fringe sections of the population and showed an anti social behaviour pattern.
