This market will resolve to "Yes" if the CDC issues a Level 3 (“Reconsider Nonessential Travel”) Travel Health Notice for any disease by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A Level 3 notice listed for any amount of time during this market’s timeframe will suffice for a "Yes" resolution. The primary resolution source for this market will be the CDC’s official Travel Health Notices page (https://wwwnc.cdc.gov/travel/notices); however, a consensus of credible reporting will also be used.The recent multi-country hantavirus outbreak—eight cases including three deaths from Andes virus linked to the MV Hondius cruise ship in the South Atlantic, confirmed by WHO on May 6—has driven Polymarket's 75.5% implied probability for a CDC Level 3 Travel Health Notice by December 31, as traders anticipate potential escalation amid CDC's Health Alert Network advisory (HAN-00528) and Emergency Operations Center activation at its lowest Level 3 tier for monitoring. No Level 3 notices are active per CDC's latest update, though ongoing Level 2 alerts for meningococcal disease in the Democratic Republic of the Congo, clade II mpox in Ghana and Liberia, and persistent H5N1 reservoirs in U.S. wild birds and poultry signal elevated outbreak risks. Epidemiological surveillance and seasonal transmission dynamics remain pivotal, with model projections highlighting uncertainty in human-to-human spread thresholds.
