Figure 1 Reported tuberculosis incidence and mortality rates, Canada, 1924 to 2011

This image is a graph showing the decline in the number of cases and the number of deaths from tuberculosis in Canada over time. The x axis represents the time between 1924 and 2011. The y axis represents rates per 100,000 population starting with 0 at the bottom to 120 cases at the top. Two lines appear on the graph. The pink line represents the number of cases, the red line represents the number of deaths. There was an irregular rise in cases to approx. 84 cases per 100,000 in 1931, a drop to 70 cases per 100,000 in 1938 and then a peak of 104 cases per 100,000 in 1948. There was a gradual decline to 90 cases per 100,000 by 1955 and then a steep decline in the number of cases to 26 cases per 100,000 by 1967. There was then a steady gradual decline to approximately 8 cases per 100,000 by 1987, down to the current level of 4.6 cases per 100,000 in 2010. The red line for number of deaths shows a high of approximately 84 cases per 100,000 in 1924. This then takes a moderate decline to a mortality rate of 46 cases per 100,000 in 1948 (when the number of cases was the highest). There is then a drop in the mortality rate to approximately 8 cases per 100,000 by 1967; the mortality rate then hovers close to zero between 1977 and 2011.
