Comparison of reported TB cases among foreign-born persons within 1 year after arrival in the United States and smear-negative/culture-positive TB cases diagnosed overseas among U.S.-bound immigrants and refugees by the culture-based algorithm, 2002–2012

Definitions: TB = Tuberculosis.

* Had the culture-based algorithm not been implemented, cases of smear-negative/culture-positive TB would very likely have been imported to the United States and counted as reported cases among foreign-born persons within 1 year after arrival by the U.S. National TB Surveillance System.
