Hantavirus pandemic in 2026? [Polymarket]
Resolution criteria Follows the identical Polymarket resolution (https://polymarket.com/event/hantavirus-pandemic-in-2026). 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. A consensus of credible reporting may also be used. Background Hantaviruses are a family of viruses spread mainly by rodents. In humans, they can cause Hantavirus Pulmonary Syndrome (HPS) and Hemorrhagic Fever with Renal Syndrome (HFRS). While Hantaviruses can cause severe, life-threatening disease, transmission is typically through contact with infected rodent excreta, not via human-to-human transmission. Historically, human-to-human transmission of Hantavirus is extremely rare, making the potential for a global pandemic fundamentally different from respiratory viruses like influenza or SARS-CoV-2.
