Annual trends of TB incidence rates among immigrant workers (presented as curve charts) or admission numbers of immigrant workers (presented as bar charts) in Taiwan during 2011–2014. There was an increasing trend in TB in Indonesia (TB incidence rates: 105.7–135.3/100,000 person-years) and a parallel increasing trend in the admission numbers of Indonesian immigrants (151,588-213,486). With (2011–2013) or without (2014) a relocation policy for TB cases, immigrant workers from highly endemic countries showed no significant differences in TB incidence between 2013 and 2014, with the exception of a decline in Vietnam and an increase in Indonesia. In parallel, the fluctuations of the TB incidence rates among immigrant workers of each nationality in Taiwan were significantly positively associated with (R = 0.74, 2011–2014) and lower than those in the original countries
