Abstract
Despite unprecedented overall tuberculosis (TB) control in the US, TB continues to be a global problem, reflected in the fact that incident cases of active TB among foreign-born people in the US are 12 times higher than that of native-born people. As a result, for those applying for refugee status in the US, the Centers for Disease Control and Prevention’s Division of Global Migration and Quarantine (CDC/DGMQ) requires a pre-departure medical evaluation that, among other things, is designed to identify people with active, infectious tuberculosis disease. The overseas medical screening does not screen for latent tuberculosis infection (LTBI), and since it is estimated that in the US the number of foreign-born persons with LTBI is nearly 7 million people, the US-based physician has an important role in screening newly-arrived refugees for LTBI. Screening for LTBI can be done using a tuberculin skin test (TST) or an interferon-gamma release assay (IGRA), both of which have advantages and disadvantages. A positive screening test should compel the physician to conduct follow up testing. Based on testing results, refugees are treated for either LTBI or active TB. Treatment of LTBI most commonly consists of daily isoniazid for nine months, but CDC recognizes equivalent efficacy of other alternative regimens also.
