No CDC Level 4 “Avoid All Travel” notices are active as of early June 2026, with the agency’s official notices page confirming zero entries at that threshold. Recent health alerts remain at Level 1 or 2 for dengue across 16 countries and polio circulation in parts of Africa and Asia, while Ebola monitoring in the Democratic Republic of the Congo has prompted enhanced screening but not a Level 4 designation. These contained outbreaks and lower-tier precautions reflect current epidemiological data showing no extreme, unmitigable global health risks meeting the criteria for a highest-level notice before year-end. Trader consensus at 76.5% against issuance aligns with the absence of rapid escalation signals in official surveillance.
