Trader consensus on Polymarket reflects an 88.5% implied probability against a new pandemic in 2026, driven by robust global health surveillance from WHO and CDC showing no novel pathogen with sustained human-to-human transmission capable of triggering a Public Health Emergency of International Concern (PHEIC) or pandemic declaration. Despite ongoing concerns like H5N1 avian influenza's animal outbreaks and sporadic human cases—now over 890 globally since 2003 without efficient spread—and mpox clade I's multi-country epidemic exceeding 179,000 cases mostly in Africa, these remain contained regionally per official reports. Recent BA.3.2 COVID variant detections in 23 countries since late 2025 do not qualify as "new," while WHO's April 7 R&D roadmaps emphasize preparedness amid steady respiratory season trends. Key upcoming data includes weekly avian flu updates and mpox surveillance through year-end.
