Quebec Faces alarming Rise in tuberculosis Cases, Especially in Montreal
Table of Contents
A concerning surge in tuberculosis (TB) cases is gripping Quebec, with Montreal and teh Nunavik region experiencing the most significant increases. Health officials are responding to a reversal of decades-long progress in controlling the infectious disease, raising questions about systemic vulnerabilities and access to care.
A Dramatic Increase in Infections
In 2024, Montreal alone saw a 54% jump in the tuberculosis rate compared to the average of the previous 13 years, according to Dr. Faiz Ahmad Khan, a pulmonologist and director of clinical tuberculosis services at the mcgill University Health Center. “It’s not a fluctuation,” Dr. Khan emphasized. “It’s a reversal of the trend.” This alarming trend continued into 2025, with 516 cases reported province-wide, representing an incidence rate of 5.8 cases per 100,000 inhabitants.
For context, Quebec’s health ministry reports that the number of cases had remained relatively stable between 200 and 280 over the past three decades. In 2024, 467 cases were recorded, with an incidence rate of 5.28 per 100,000. These figures are notably higher than the Canadian average of 4.9 cases per 100,000 in 2023.
The Nunavik region, a predominantly Inuit territory in northern Quebec, is also facing a disproportionately high rate of tuberculosis, with an incidence rate exceeding 200 per 100,000. This situation is compounded by challenges related to remote access, housing, and social determinants of health. Public health and social services is ongoing to address the situation.
Addressing the Crisis: A Multi-Faceted Approach
A provincial and local task force has been established to identify all aspects of the crisis and implement effective follow-up measures. The ministry is also working with the federal government and territories to develop a national tuberculosis strategy.
A key factor in the recent surge appears to be the origin of cases in Montreal. Since 2015,approximately 90% of recorded cases have involved individuals born outside of Canada who contracted the disease abroad. However, certain populations within Quebec are at increased risk, including the homeless, individuals in detention centers, and those living with someone diagnosed with tuberculosis.
Understanding Tuberculosis: Transmission,Symptoms,and Treatment
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and can develop quickly upon initial exposure,or remain dormant for years. According to Dr.Khan, transmission occurs thru inhaling droplets containing the bacteria, requiring prolonged exposure to become infected. While contagious, he stresses that “there is no need to panic about tuberculosis.”
Common symptoms include a persistent cough lasting several weeks, fever, severe fatigue, loss of appetite, night sweats, and weight loss. Treatment involves a multi-month course of medication, with a high recovery rate when taken as prescribed. Though, Dr. Khan cautions that tuberculosis can leave lasting effects, such as lung scarring or cardiovascular complications, impacting patients’ quality of life.
Systemic Issues and the Need for Increased Funding
The rise in tuberculosis cases, according to Dr. khan, reflects underlying structural problems in prevention and detection. He argues that insufficient funding for TB care jeopardizes the health of all residents, not just vulnerable groups. “universal access to tuberculosis care,which covers all costs for people at risk of or suffering from tuberculosis,is much less expensive than managing epidemics,caring for people hospitalized for tuberculosis and emergency interventions,” he stated.
Currently, treatment is mandatory upon diagnosis in Quebec, but Dr. Khan advocates for increased provincial funding to cover care for individuals without insurance. He poignantly describes Montreal as “the place where global TB meets local realities,” highlighting the intersection of migration, housing insecurity, and inequalities in healthcare access.
Ultimately, Dr. Khan emphasizes that tuberculosis is a public health concern affecting all Quebecers, demanding a comprehensive and adequately funded response.
