%X introduction: control of tuberculosis (tb) in healthcare workers requires an early recognition of contacts, the adoption of efficient protective measures and screening for cases of latent tuberculosis (tl) and recent tl. aims: systematic screening for tb and tl in healthcare workers with contact with patients or other workers with tb and risk of contagion. material and methods: in a hospital with approximately 5400 workers 13 screenings were performed september 2007- december 2008 due to risk of continued tb. these consisted of clinical observation, tuberculin skin test (pt), quantiferon£¿-tb gold (qtf) test if pt ¡İ10mm and <15mm and chest x-ray. the diagnoses were performed according to the recommendations of the portuguese pulmonolgy society (spp). results: 792 workers (563; 229) were included in the 13 screenings. of these, 75 presented symptoms and 31 had radiology abnormalities. pt was performed in 490 workers, with results <10 mm in 250, ¡İ10 and <15 mm in 175 (qtf positive in 36) and =15 mm in 65. of the screened workers, 280 had a previous pt =15 mm, and therefore it was not repeated. 1 case of active tb was diagnosed in a worker, as well as 408 cases of tl (51.5%) and 42 cases of recent tl (5.3%). conclusions: tb is considered an occupational disease in healthcare workers. the screening of contacts and tl cases is an important tool for an early diagnosis of active disease and for identifying the cases with higher risk of future disease.
