A new commentary in The Lancet argues that preventing zoonotic disease spillover must be a central focus of the 2026 UN High-Level Meeting on pandemic prevention, preparedness, and response (PPPR). The meeting, agreed upon by the UN General Assembly, will review the implementation of a 2023 political declaration and consider newly adopted international health regulations. This call comes as global attention to pandemic threats has reportedly waned despite persistent risks from diseases like mpox and avian influenza.
The devastation of the COVID-19 pandemic initially propelled PPPR to the top of the global agenda. However, the commentary notes that focus has since been diverted by other pressing issues, including inflation, conflict, and the challenges of artificial intelligence proliferation. The 2026 meeting represents a critical opportunity to refocus international efforts on preventing the next major outbreak before it begins.
The planned High-Level Meeting will specifically assess progress on the 2023 Political Declaration on PPPR. It will also consider the amendments to the International Health Regulations adopted in 2024 and the anticipated 2025 WHO Pandemic Agreement as interconnected processes. The commentary frames these instruments as a foundation for a more robust global health security architecture.
Elevating spillover prevention—stopping pathogens from jumping from animals to humans—could shape national policies and international funding for surveillance at the human-animal interface. Success at the 2026 meeting would require sustained political will and coordination between health, environmental, and agricultural sectors worldwide. The outcome could define the global approach to pandemic risk for the next decade.
Failure to secure strong commitments, however, could leave the world vulnerable to repeating the cycles of panic and neglect that have characterized past responses to emerging infectious diseases.
