This market will resolve to "Yes" if the CDC issues a Level 4 (“Avoid All Travel”) Travel Health Notice for any disease by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A Level 4 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.CDC maintains no active Level 4 "Avoid All Travel" designations, with recent notices capped at Level 2 for meningococcal disease outbreaks in the Democratic Republic of the Congo (updated March 24, 2026) and yellow fever increases in Venezuela, anchoring trader consensus at 79.5% implied probability for "No" issuance by December 31. These top-tier warnings are reserved for extreme, life-threatening risks with widespread transmission and limited containment, such as historical Ebola zones—criteria unmet amid current CDC and WHO surveillance showing contained epidemics of polio, chikungunya, and clade II mpox. The April 16 global dengue Level 1 update reflects routine monitoring without escalation signals; avian influenza human cases remain sporadic with no sustained transmission, though novel pathogen emergence could alter market sentiment ahead of year-end reporting.
