The hamlet of Qikiqtarjuaq, population 600, has the highest tuberculosis rate in Nunavut. With 10 per cent of its residents infected with active or latent tuberculosis, a task force was recently sent to the community to hold screenings. Dr. Sarah Giles says more needs to be done to stop the spread of the disease. (Nick Murray/CBC) The depth and scale of this problem should leave every Canadian outraged.
Most Canadians think of poor countries when they think about tuberculosis (TB), a disease intimately connected with substandard living conditions.
Last year, 100 people in Nunavut were diagnosed with active TB — a number many Canadians would find shocking.
To put that number in perspective, Nunavut now has the same incidence rate of TB as Somalia, 261 cases per 100,000. The rest of Canada has an incidence rate of only 0.6 cases per 100,000 people.
With rare exceptions, such as when children like 15-year-old Ileen Kooneeliusie of Qikiqtarjuaq , die from the disease, as she did in January 2017, the Canadian media have not reported on the longstanding problem in the North.
Some Canadians may be aware of the March announcement by the federal government and Inuit Tapiriit Kanatami (ITK), the national representative organization for Inuit in Canada, which vowed to eliminate tuberculosis in the northern regions of Canada inhabited by Inuit by 2030. The federal government also pledged $27 million to eliminate TB in Inuit communities.

The proposed spending comes at the same time that the incidence rate of tuberculosis has hit crisis levels in Nunavut. Stopping the current outbreak will require a herculean effort. Worse yet, the current TB outbreak may be more extensive than we realize because the existing data are poor quality.
Tuberculosis has two forms: active and latent. When people are exposed, they first develop latent TB — a non-infectious form of the disease.
Approximately five to 10 per cent of people with latent TB will develop active TB, which makes them sick. While most people think of TB as disease of the lungs, it can be found virtually anywhere in the body, but is only contagious when it is in the lungs.
A government report obtained through an access to information request showed an active TB rate of 1,020 per 100,000 infants — more than one in 100 infants — in Nunavut in 2017.
In the rest of Canada, the rate is just three infants in 100,000.
Though no babies died of tuberculosis in Nunavut in 2017, even successfully treated TB can cause lifelong health consequences, such as cognitive impairment.
Because babies develop active TB quickly; TB in infants indicates high levels of disease circulating in a community. Nunavut only tracking active cases
At present, Nunavut only tracks active cases of TB but not latent cases.
People who have latent TB and are at high risk of developing active TB, such as those with weakened immune systems or kidney failure, can be offered preventative treatment — but the government of Nunavut does not keep track of those who are offered preventative treatment or those who complete, decline, or fail to finish treatment.It is important to track people with latent tuberculosis.They do not have symptoms, but they can convert to active TB and spread the disease, believing they simply have a cough.
