The present study was designed to determine the incidence of tuberculosis (TB) in tertiary care hospital (Mayo hospital, Lahore) from January 2014 to June 2014. Several demographic factors analyzed were found to be significant in transmission of pulmonary tuberculosis (p < 0.05) except marital status (p=0.09) and age (p=0.212). Out of 50 suspected patients, 26 (52%) cases were recorded as a positive for pulmonary tuberculosis: out of which, six healthcare (HCWs) were found. Mean incidence of TB was 23% (6 out of 26) for all HCWs, 4 were nurses and 2 for other professionals, while for general population 79% (20 out of 26) cases were positive. The observed ratio among HCWs and general population was 60% and 50% respectively. It is concluded that incidence of TB among HCWs was more than general population. The reason is deprived medical conditions and facilities in Pakistan. Control programs to stop nosocomial transmission of TB should be adopted in hospitals to reduce risk for HCWs. Finding the risk of TB among HCWs is crucial to enable authorities to take preventive measures in health care facilities and shield HCWs.
