Tuberculosis outbreaks in 3 Nunavut communities still ongoing years later (CBC)

Excerpts from the research article:

Highlights

• Tuberculosis (TB) is the top cause of infectious disease mortality.
• TB incidence between Indigenous and non-Indigenous Canadians is disproportionate.
• Alaska, USA and Nunavut, Canada, home to the indigenous, face similar challenges.
• Alaska focused on community-based healthcare delivery in Native communities.
• Nunavut’s weak community healthcare infrastructure is an obstacle to TB control.

Background

Both Alaska and Indigenous North Canada share similarities in geographic location, population, and a history of colonization. While both regions have seen a significant decline in tuberculosis (TB) prevalence over the last century, Nunavut, Canada, has reported a troubling resurgence of TB cases since the early 2000s.

Method

This study applied a modified version of the WHO Health Systems Building Blocks Framework to assess TB programs in both regions through a contextual lens. A scoping review inspired review of academic literature, government reports, and open-source documents (1950–2019) informed the analysis.

Results

In Indigenous Northern Canada, TB control is hindered by limited healthcare investment, reliance on evacuation policies, and workforce shortages. Social determinants, such as overcrowded housing and food insecurity, exacerbate the issue. In contrast, Alaska’s early infrastructure development led to the establishment of local healthcare services, workforce training, and community-based programs, resulting in more effective TB management.
