This qualitative study examines how people experiencing homelessness in Ottawa, Canada were stigmatized during the COVID-19 pandemic as dangerous vectors of infection rather than as a vulnerable population deserving of care. Drawing on interviews with 28 service providers and a media scan of 71 articles, the authors found that public health messaging, media reporting, and public attitudes framed unhoused individuals as risky and irresponsible, leading to further social exclusion, blame internalization, and trauma. The paper advocates for trauma- and violence-informed care in public health responses to prevent further stigmatization of marginalized populations during health emergencies.
