Abstract
|
|
|
|
Tuberculosis (TB) is an infectious disease caused by bacteria (Mycobacterium tuberculosis). TB is spread from one person to another through the air. The degree of transmission of TB is known to be dependent upon frequency, distance, and duration of contact with TB patients. In February, 2019, an employee was reported as a tuberculosis patient (i.e., index case) and contact investigations were conducted on all 53 employees according to the National Tuberculosis Control Programme. As a result, an additional 5 cases were classified as TB patients, and 17 cases were diagnosed as latent TB infection (LTBI). The additional TB patients worked on the same floor as the index case. Furthermore, TB genotyping could not be analyzed by the TB culture test of additional patients.
