Current surveillance from WHO and CDC indicates no novel pathogen with sustained global human-to-human transmission meeting pandemic criteria, underpinning the 94.5% market-implied odds against a 2026 declaration. The Bundibugyo Ebola outbreak in the DRC, declared a PHEIC in May with over 4,500 confirmed cases and ~47% case fatality, remains regionally contained due to direct-contact transmission requirements, despite spread to Uganda and isolated imports elsewhere. Measles and other vaccine-preventable diseases show elevated activity from immunity gaps but lack the transmissibility or novelty for pandemic status, while COVID-19 circulates endemically at low levels. Realistic challenges include rapid viral mutation enabling efficient airborne spread or undetected zoonotic emergence before year-end monitoring updates.
