Current CDC Travel Health Notices show no Level 4 (“Avoid All Travel”) designations, reflecting the absence of any disease outbreak meeting the agency’s extreme-risk threshold where no effective precautions exist. Contained Ebola activity in the Democratic Republic of the Congo and a recent hantavirus event remain at lower advisory levels, while dengue warnings stay at Level 1. Official surveillance data indicate case trends and transmission patterns do not yet approach the sustained high-fatality or novel-pathogen criteria historically required for Level 4 issuance outside major pandemics. Traders therefore assign a 77% implied probability to “No” by December 31, 2026, pending any rapid escalation that would trigger new CDC model runs or designations.
