HomeIn the early 20th century, TB was a major cause of morbidity and mortality in Canada. Figure 1 displays records of active TB disease going back as far as 1924, although nationwide systematic reporting was only instituted in 1933.
From the available records, 1 in 13 reported deaths in Canada in 1926 were due to TB, a number slightly higher than the number of deaths reported for cancer at the time. As a result of improved living conditions and healthcare and prevention, as well as the development and implementation of public health measures and availability of antibiotics effective against M. tuberculosis, the morbidity and mortality rates have significantly decreased over time (Figure 1).
