Global surveillance from the WHO and CDC shows no novel pathogens with sustained human-to-human transmission capable of meeting pandemic criteria through late August 2026, underpinning the 94.5% market-implied probability of no new declaration by year-end. Localized activity includes the Bundibugyo Ebola outbreak declared a public health emergency of international concern in the DRC and Uganda, alongside measles surges, dengue expansion tied to climate factors, and sporadic avian influenza detections, none of which exhibit the rapid global spread or immune-evasion traits seen in prior pandemics. Historical patterns confirm such events remain infrequent, requiring specific combinations of transmissibility and susceptibility absent in current data. Trader consensus aligns with this low baseline risk, though an unexpected viral reassortment enabling efficient airborne spread or surveillance gaps could still alter outcomes before December.
