The results showed that 13 TB patients were diagnosed in 2242 employees, 12 of whom had an attack within one year; of the 224 employees in the work group where the first onset patient operated, the strongly positive rate of PPD test was 63.8% (143/224), and a definite diagnosis was confirmed in 7 patients; of the 36 employees on the dormitory floor where the first onset patient lived, the strongly positive rate of PPD test was 75.0% (27/36), and a definite diagnosis was confirmed in 4 patients. It was analyzed that two outbreaks in this epidemic were resulted from the same source; the primary causes were the absence of timely quarantine and normative therapy and management, as well as the poor ventilation of workshops and buildings.
