How the U.S. presidential election impacts global health: governance, funding, and beyond

The United States plays a crucial role in shaping global health through its policy decisions and engagements. Historically, bipartisan support underpinned U.S. involvement in multilateral and bilateral global health initiatives in advancing its national health, security interests, and foreign policy. However, recent decades have witnessed increased politicization and polarization of global health and fluctuating stances between Republican and Democratic administrations. This commentary speculates the potential implications of the 2024 presidential election on global health, focusing on how ideological differences between parties and previous administrative actions might affect U.S.'s strategies in addressing key global health issues, including governance, funding allocation, sexual and reproductive health policies, responses to humanitarian crises, and efforts to combat climate change. The election may be a critical juncture that could determine whether the U.S. global health strategies will continue to reflect the globalist and liberal policies typically associated with recent Democratic administrations or shift back to the isolationist tendencies observed during Trump's presidency. The outcome will significantly determine the direction of U.S. global health policy and its broader implications for global health equity and security. The conclusions emphasize the necessity of maintaining strong international cooperation and commitment to health as a global public good.
