Epidemiology of Tuberculosis

In 2015 there were an estimated 10.4 million new cases of tuberculosis (TB) worldwide (WHO). In Canada there are approximately 1,600 cases of tuberculosis reported each year, with an incidence rate of 5.0 per 100,000. In 2014, Manitoba had 135 cases of tuberculosis, an incidence rate of 10.5 per 100,000. Manitoba has a higher burden of tuberculosis than most regions of Canada. In Manitoba, TB is disproportionately seen in Canadian-born Indigenous people and foreign-born individuals from countries where TB is endemic (PHAC and CTS). 

The Winnipeg Health Region and the Northern Health Region have 90% of the TB cases in Manitoba (MB Health).  In Manitoba, there are more males diagnosed with TB than females. All age groups are affected by TB, although people between 35 to 44 years of age are most represented. In Manitoba, 116 of the 135 cases of TB were respiratory and 19 cases were non-respiratory. The most common site of non-respiratory TB is the peripheral lymph nodes (PHAC).
