Current CDC surveillance data through mid-May 2026 show no Level 4 Travel Health Notices in effect, with the highest active alerts at Level 3 for Ebola Bundibugyo virus in the Democratic Republic of the Congo and Uganda. These outbreaks reflect elevated but containable transmission risks where standard precautions remain viable, falling short of the agency’s threshold for “extreme health risk with no available precautions.” Ongoing measles transmission exceeds 1,800 U.S. cases yet registers only lower-level notices, while global dengue activity stays at Level 1. Historical patterns indicate Level 4 issuances require novel pathogens or uncontrolled spread beyond current model projections, supporting trader consensus that escalation before year-end remains unlikely absent major surveillance shifts.
