Current CDC monitoring shows no Level 4 “Avoid All Travel” health notices active as of early June 2026, with the agency maintaining Level 3 advisories for the recent Ebola outbreak in the Democratic Republic of the Congo and lower-tier notices for chikungunya and dengue in affected regions. Traders assign 76.5% probability to “No” through year-end because sustained low U.S. public risk assessments, effective containment measures, and the absence of uncontrolled high-mortality pathogens with no available precautions align with historical thresholds for Level 4 issuance. Ongoing surveillance by the CDC and WHO, combined with seasonal patterns of mosquito-borne and respiratory viruses, supports expectations that conditions will not escalate to the extreme-risk category required for such a notice before December 31.
