Current CDC surveillance through mid-May 2026 shows no active Level 4 Travel Health Notices, with alerts limited to Level 1–3 for dengue, chikungunya, Ebola Bundibugyo, and measles clusters. Official data indicate contained transmission patterns for respiratory viruses, vector-borne illnesses, and meningococcal disease, none reaching the extreme-risk threshold of widespread community spread without effective precautions that defines Level 4. Recent issuance of a Level 3 notice for Ebola in the Democratic Republic of the Congo on May 18 reflects agency thresholds for escalation, yet model consensus and historical outbreak patterns suggest limited potential for rapid deterioration to avoid-all-travel conditions before year-end. Ongoing monitoring through summer and fall surveillance networks will provide key updates on case thresholds and geographic spread, though the absence of novel high-risk pathogens supports trader consensus around the 76 percent implied probability for no Level 4 notice.
