We reported changes in the working status of pulmonary tuberculosis patients after the admission to our hospital. The age of patients ranged from 20 to 69 years old, and they were admitted to the 18th ward of our hospital from April 1991 to March 1993. We sent out the questionnaire to 198 patients, and the reply was sent back from 116 patients (Male 74, Female 42). Out of the 116 patients, we excluded the unemployed, the government employees, and self-employed workers. The remaining 76 patients were examined about their working status after admission, and the results were as follows: 2 patients lost their work, 11 patients retired from the work, 2 patients faced the drop of their position, and 3 patients had their salary reduced.
