Among immigrant workers with TB whom passively identified through the misalliance surveillance algorithm including illness diagnostics compared to actively identified through mandatory screenings surveillance algorithm with a higher clinical characteristics proportion of 16.4% (189/1154) vs. 11.7% (108/926) of the smear-positive pulmonary TB cases and a lesser proportion of 70.8% (817/1154) vs. 78.5% (727/926) of the smear-negative pulmonary TB cases i.e., at higher proportions in SS+ PTB (aOR: 1.5, 95% CI: 1.1–2.0). The TB yields of the 0-, 6-, 18-, and 30-month post-entry screenings of these immigrant workers were 24.4 (95%CI 12.5–36.3), 40 (95%CI 25.1–54.9), 52.6 (95%CI 25.1–80), and 47.4 (95%CI 31.5–63.3) cases per 100,000 screenings, respectively; the respective detection proportions were 7.4% (153/2080), 13.9% (289/2080), 13.9% (290/2080), and 8.6% (179/2080) in Taiwan
