Five tuberculosis cases linked to Edmonton downtown homeless outbreak
Two additional people have tested positive for the same TB strain circulating among Edmonton's downtown unhoused population, bringing the outbreak count to five, officials say the risk to the wider public remains low.
Health officials in Alberta announced two more confirmed tuberculosis infections among people experiencing homelessness in Edmonton's downtown core, raising the outbreak total to five cases with the same strain. The province declared the outbreak in October 2025 after three vulnerable individuals tested positive for the identical bacteria. Throughout 2025, twelve TB cases were identified in the inner city, but only three matched the outbreak strain until the latest confirmations.
Primary Care Alberta and medical officers are conducting contact tracing and coordinating with inner-city agencies to limit spread, while emphasizing that the general public faces minimal risk. Infectious disease specialist Stan Houston highlighted that crowded shelters, poor ventilation and limited access to primary care fuel such outbreaks, and noted that treatment can be prolonged and difficult for unhoused patients. Beth Klingenberg of Hope Mission stressed the importance of stable housing and accessible services to ensure patients complete therapy.
Why it matters
The outbreak shows how TB can resurface in vulnerable urban populations and underscores the need for housing and health support.
