The limited May 2026 Andes hantavirus cluster aboard the MV Hondius—roughly 10 confirmed or suspected cases and three deaths among 147 passengers and crew—remains the dominant factor anchoring the 96.5% market-implied probability against a 2026 pandemic. Official surveillance from the CDC and WHO shows no sustained community transmission beyond the ship, consistent with the virus’s primary rodent-to-human zoonotic cycle and inefficient person-to-person spread that requires prolonged close contact. Epidemiological data through mid-August indicate no imported U.S. cases or exponential growth curves, aligning with historical patterns where Andes virus produces focal outbreaks rather than pandemics. Trader consensus reflects this containment, though mutation enabling efficient airborne transmission or undetected amplification in rodent reservoirs could theoretically shift dynamics before year-end.

This market will resolve to "Yes" if the World Health Organization explicitly characterizes Hantavirus, Hantavirus Pulmonary Syndrome (HPS), Hemorrhagic Fever with Renal Syndrome (HFRS), or a Hantavirus-related outbreak as a "pandemic" in an official public communication between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No".
An explicit characterization includes official WHO statements, reports, press briefings, or publications that clearly describe the outbreak as a "pandemic." A Public Health Emergency of International Concern (PHEIC) alone will not qualify unless it is also described as a pandemic.
The primary resolution source for this market will be official WHO communications.
