Gita Sen, in this article published at The Lancet on August 2024, addresses the profound concern within global health regarding the current era of polycrises—the confluence of conflict, climate catastrophe, the COVID-19 pandemic, the persistent HIV epidemic, and geopolitical and economic shocks. These intersecting crises, exemplified by ongoing atrocities in Gaza, Sudan, and Myanmar, regressive political movements, and extreme weather events, are creating a new reality characterised by unprecedented scale, severity, and complexity. This reality is not only exposing pre-existing intersectional injustices and gender-based inequalities in health but is actively exacerbating them. Consequently, health disparities within and between nations are deepening and widening, with stark divisions emerging along lines of income, gender, age, race, ethnicity, migratory status, disability, and geography.
