World TB Day 2024 – Controlling TB in Canada

Inter Medico is proud to recognize World TB Day on March 24th, 2024, with our partners from QIAGEN.



While Canada’s rates of Tuberculosis (TB) are relatively low, there were still over 1,800 cases of active TB infection reported in 2021. TB disproportionately impacts Inuit, First Nations, and foreign-born individuals living in Canada. According to 2021 figures, rates of active Tuberculosis infection among Inuit communities are 135.1 per 100,000 individuals, which is over 28x higher than in the general population (4.8 per 100,000). First Nations peoples are impacted by active  TB at 16.1 per 100,000, and people born outside of Canada experience a rate of 12.3 per 100,000. Over 75% of active TB cases were reported in individuals born outside of Canada (source:

Accessing Latent TB Testing in Canada

Screening for latent Tuberculosis infection (non-infectious carriers of TB infection) can be an effective tool to prevent future outbreaks of active TB by identifying and treating TB carriers before the disease becomes active and contagious. The QuantiFERON TB Gold Plus test from our partner QIAGEN is the most accurate and convenient test available for Latent TB infection, and it is widely available across Canada. The QuantiFERON test uses an Interferon Gamma Release Assay (IGRA) method. It is a simple blood test which does not require a second visit, and provides a reliable, objective result. Below is a list of resources regarding Latent TB testing via the QuantiFERON TB Gold Plus test across Canada:
