CDC Reports Over 2,000 Measles Cases in 2026, 93% Outbreak-Related
The CDC confirmed 2,030 measles cases in the U.S. as of June 4, 2026, with 1,890 cases (93%) linked to outbreaks. This total is rapidly approaching the full-year 2025 count. Measles is a highly contagious vaccine-preventable disease that poses particular risks to immunocompromised populations and young children. For Medicaid managed care plans, rising case counts may trigger increased EPSDT screening requirements, higher utilization of pediatric acute care and emergency services, and potential quality measure impacts related to childhood immunization rates.
Medicaid MCOs serving pediatric and immunocompromised populations may see increased acute care utilization and face pressure to improve immunization rates under HEDIS and quality bonus programs.
