Purpose:
To investigate the infection rate of tuberculosis in high-risk employees at our hospital.
Methods:
We measured interferon gamma levels in 40 employees and evaluated the infection rate in doctors working in the Tuberculosis Ward (D group), nurses in the Tuberculosis Ward (N group), and other high-risk employees (O group).
Results:
The overall infection rate including probable infection was 6/40 (15.0%). The infection rate in the N group was 0%, while those in the D and O groups were 27.3% and 20.0% respectively. No new infection of tuberculosis was observed after the introduction of tuberculosis infection measure manual of our hospital.
Conclusion:
Our hospital's tuberculosis infection measure manual was effective in decreasing the new tuberculosis infection despite a high infection rate in high-risk employees at our hospital.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
