The prevalence of tuberculosis (TB) among homeless shelter staff was assessed using the tuberculin skin test (TST) and the Quantiferon TB-Gold in tube interferon-γ release assay (QFT-TB). Investigation of 51 participants for whom both QFT-TB and TST results were available showed 47.1% and 43.1% positivity, respectively, with excellent (92%) concordance between the 2 tests. The high risk for acquiring occupational TB necessitates the development of TB surveillance protocols for homeless shelter staff in Italy.
