Screening for pulmonary tuberculosis using chest radiography in new employees in an industrial park in Taiwan.

Background: Pulmonary tuberculosis (TB) is prevalent in Taiwan, but it is suspected that its occurrence has been underestimated by the National TB Surveillance Program. A pre-employment health examination is mandated by law in Taiwan, providing a mechanism to assess the occurrence of TB more accurately.

Methods: A pre-employment TB screening program of an industrial park was used to evaluate the performance of the National TB Surveillance Program in Taiwan.
