Title Prevalence of latent tuberculosis infection among health care workers in a hospital for pulmonary diseases

Abstract The study was designed to estimate prevalence of latent tuberculosis infections (LTBI) among 270 health care workers (HCW) in a hospital specialized in pulmonary diseases, using both Interferon-gamma release assay (IGRA) and tuberculin skin test (TST) methods. The prevalence of LTBI was 7.2%. In HCW younger than 30 years LTBI prevalence was 3.5% and in those older than 50 years 22%. Physicians and nurses showed a higher prevalence (10.8%) than other professions (4.5%). The risk factors for LTBI were age >50 years (odds ratio OR 9.3), working as physicians/nurses (OR 3.2) and no previous TST in medical history (OR 4.4) when compared to those with a negative TST. The higher LTBI prevalence in older HCWs might be due to the cohort effect or the longer time at risk.
