Rate of latent tuberculosis infection detected by occupational health screening of nurses new to a london teaching hospital.
The prevalence of latent tuberculosis infection in a cohort of nurses new to a London hospital was 7.6% (13 of 171), using an interferon-gamma (IFN-gamma) release assay, and 16.2% (24 of 148), using the tuberculin skin test. On multivariate analysis, birth in a country with tuberculosis prevalence of more than 40 cases per 100,000 population was associated with positive results of both the IFN-gamma release assay and the tuberculin skin test.
