Figure 2. Time from arrival in Canada to diagnosis of foreign-born culture-positive tuberculosis cases by drug susceptiblility pattern of incident case isolate (1997–2008).

Time from arrival to diagnosis was calculated by subtracting year of arrival from year of diagnosis. Year of arrival was known for 6928 of the 10589 foreign born cases. Cases with time since arrival between 0–55 years displayed. Bar graph represents the absolute number of cases diagnosed, and line graph represents the cumulative proportion of foreign-born TB cases diagnosed since their time of arrival in Canada.
