Global health diplomacy in humanitarian action.

This commentary explores the intersection of Global Health Diplomacy (GHD) and humanitarian action within Fragility, Conflict, and Violence (FCV) contexts. It aims at addressing the multifaceted challenges faced by communities living in these environments, where a convergence of multiple factors, including over 110 active armed conflicts, creates complex emergencies impact on large populations globally. This commentary holds three primary significances: 1)  it scrutinizes the profound and enduring health consequences of major humanitarian crises on last-mile populations, highlighting the pivotal role of health diplomacy for better navigating humanitarian challenges; 2) it advocates for a paradigm shift in humanitarian approaches, recognizing GHD's potential in shaping international cooperation, building consensus on inclusive global health policies, and enabling more effective interventions; 3) it underscores the operational impact of health diplomacy, both at diplomatic tables and on the frontlines of humanitarian efforts. Through real-world cases such as the cholera outbreak in Yemen and the response to Ebola outbreaks in DRC, the paper illustrates how diplomatic dialogue can impact health outcomes in fragile settings.
