Background: The risk of tuberculosis among HCW were higher than another profession since the opportunity of contact with TB patients will be more frequent. The risk of LTBI were higher for people living in high burden TB country, then HCW in Indonesia have both risk. Objective: This study was done to know the risk factors for LTBI cases in HCW at infectious disease hospital. Methods : A cross-sectional study design, we examined 108 HCW at Sulianti Saroso Infectious Diseases Hospital (SSIDH), using TST with PPD RT 23 then measurement the TST after 48-72 hours. TST result with induration more than 10 mm, no TB symptoms and normal CXR will be determined as LTBI. Result : The prevalence of LTBI is 49%, as many as 53 out of 108 health workers take the TST. There were significantly different among HCW working for more than 5 years (44.5%) and before (4.6%). HCW who work for more than 5 years are 4.3 times more likely to be sick with LTBI compared to workers who work for <5 years (95% CI: 1.4-12.7). Conclusion: This study showed an increased risk of LTBI with long as the duration of work. Therefore it is important to improve the infection control program.
