The COVID-19 pandemic exposed and exacerbated deep-rooted health inequities, disproportionately affecting marginalized communities. While the immediate crisis has passed, there remain long-term impacts on people's physical, mental, and social health. This edited collection applies a health justice framework—rooted in social justice—to examine the pandemic's effects on various populations, including people experiencing homelessness, youth, and students in health education. In doing so, this collection offers evidence-based recommendations across healthcare, policy, and education. This collection can help address educators, healthcare workers, policymakers, and other key stakeholders address ongoing and emerging health inequities.
