Tuberculosis Evidence Review — Newly Arriving Immigrants

This evidence review by Greenaway C et al., published in CMAJ (2011), provides a systematic examination of tuberculosis epidemiology in immigrant and refugee populations arriving in Canada. It outlines indications for latent TB screening, comparing tuberculin skin test (TST) and interferon-gamma release assay (IGRA) approaches, and presents management pathways and treatment protocols.  The review includes pediatric-specific considerations, noting that IGRA is not recommended for children under 2 years of age and that TST is appropriate from 6 months to 2 years. It also references high-TB incidence country lists to guide screening decisions. This resource supports clinicians in applying evidence-based TB screening strategies tailored to the migration context of their patients.
