Tuberculosis Resurgence in Saskatchewan: A Deep Dive into Causes and Future Strategies
Saskatchewan is currently facing elevated rates of tuberculosis (TB), a contagious infectious disease, particularly in its northern regions and among Indigenous communities. Recent investigations have linked a cluster of cases to a homeless shelter in Prince Albert, highlighting the vulnerability of those experiencing housing insecurity.
The Prince Albert Outbreak and Public Health Response
An investigation into a shelter in Prince Albert identified 11 cases of tuberculosis over a 12-month period. Saskatchewan’s Chief Medical Health Officer, Dr. Saqib Shahab, emphasized that while these cases are concerning, the risk to the general public remains low. Testing and contact tracing were conducted with individuals connected to the shelter, including diagnostic tests like blood tests and X-rays, carried out with sensitivity towards vulnerable populations.
Disproportionate Impact on Vulnerable Populations
Dr. Shahab noted that tuberculosis disproportionately affects Indigenous people and newcomers to Canada. The Northern Inter-Tribal Health Authority (NITHA) reports that TB rates in northern Saskatchewan are 19 times the national average. Currently, approximately 64 people are being treated for active TB and latent TB infection across 11 northern communities.
The Role of Housing and Socioeconomic Factors
Dr. Nnamdi Ndubuka, chief medical health officer for NITHA, stresses that addressing housing conditions is crucial to long-term control of TB. Overcrowded living situations facilitate the effortless spread of the bacteria through airborne transmission. Without improvements in housing, investments in diagnostics and treatment will have limited impact.
Treatment and Prevention: A Curable Disease
Tuberculosis is treatable and curable with a course of oral antibiotics, typically lasting six months. After two weeks of treatment, individuals are no longer infectious. But, adherence to the full treatment regimen is vital to prevent the development of drug-resistant strains. Community tuberculosis nurses play a key role in ensuring medication adherence.
Saskatchewan’s TB Rates Compared to National Averages
Saskatchewan’s TB rate, at 10.9 per 100,000 people, is higher than the Canadian average of 6.1 per 100,000 in 2024. Nunavut, the Northwest Territories and Manitoba are the only regions with higher rates. Approximately 60 to 70 per cent of cases in Saskatchewan occur within the Indigenous population in northern communities.
Research and Future Strategies
Researchers, like Dr. Neeraj Dhar at the Vaccine and Infectious Disease Organization in Saskatoon, are actively working to identify new molecules for TB treatment and shorten the duration of antibiotic regimens. Provincial health partners are developing a refreshed provincial tuberculosis strategy to further reduce transmission rates.
Understanding Tuberculosis: Symptoms and Screening
Early symptoms of tuberculosis include a persistent cough, phlegm, headaches, fatigue, weakness, and fever. Individuals arriving in Canada from countries with high TB rates are often screened with chest X-rays or ultrasounds to prevent new infections. Overcoming stigma and encouraging early diagnosis are essential components of effective TB control.

While a vaccine against tuberculosis, Bacille Calmette-Guérin (BCG), exists, it is not currently available in Canada.
