The rapid containment of the May 2026 MV Hondius outbreak—limited to 13 confirmed or probable Andes hantavirus cases and three deaths—underpins the 96.3% market-implied probability against a 2026 pandemic. Andes virus, the sole hantavirus strain capable of person-to-person spread, requires prolonged close contact rather than efficient respiratory or casual transmission, as confirmed by WHO, CDC, and ECDC sequencing and contact-tracing data showing no secondary chains beyond the initial zoonotic spillover. Endemic South American patterns, including roughly 100 annual Argentine cases and 102 reported in the 2025–2026 season, remain localized with standard rodent-reservoir dynamics. While climate-driven rodent surges or rare viral adaptation could theoretically elevate spillover risk, current surveillance indicates stable low transmissibility and no sustained community circulation.

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.
