The limited May 2026 Andes hantavirus outbreak on a cruise ship, which produced just 13 confirmed or probable cases and three deaths before rapid containment, underpins the 96.1% market-implied probability of no pandemic in 2026. Andes virus is the sole hantavirus capable of person-to-person transmission, yet this requires prolonged close contact rather than efficient respiratory spread; most hantaviruses transmit primarily via rodent excreta and cause sporadic hantavirus pulmonary syndrome or hemorrhagic fever with renal syndrome without sustained chains. Official assessments from the WHO, CDC, and ECDC rate the global risk as very low, consistent with historical patterns of small, localized clusters. A realistic shift would require the virus to acquire mutations enabling airborne or sustained community transmission, or multiple simultaneous rodent-driven outbreaks exceeding typical case counts, though current surveillance data show no such trajectory.

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.
