Current epidemiological data from the CDC show no active Level 4 Travel Health Notices, with all recent alerts limited to Level 1 or 3 for measles, dengue, and select viral outbreaks. Respiratory illness trends, including COVID-19 and influenza, indicate declining or stable transmission across most states as of mid-May 2026, reducing the likelihood of an extreme-risk scenario requiring “Avoid All Travel” guidance. Surveillance reports highlight moderate measles case counts without the rapid, uncontrolled spread or novel pathogen characteristics that historically trigger Level 4 designations. Traders appear to weigh the absence of emerging high-impact threats and standard seasonal patterns against the slim chance of an unexpected escalation before year-end. Official monitoring updates through summer and fall will provide the next clear signals for any shift in this assessment.
