Measles Cases in the US Hit 35-Year High as Vaccination Rates Fall
Measles cases in the US have reached 2,318 so far in 2026, surpassing last year’s total and marking the highest annual tally in more than three decades, public health officials report. The surge in measles cases in the US has been driven by falling MMR coverage and multiple outbreaks across the country, a trend the Centers for Disease Control and Prevention is tracking closely.

CDC: U.S. Measles Cases Top 2,300 This Year
The CDC’s cumulative case counts put confirmed infections at 2,318 as of late July, eclipsing 2025’s total of 2,289 and making 2026 the worst year for measles since the early 1990s. Public health analysts say this level of transmission has not been seen since the period of 1989–1991, when tens of thousands were infected before widespread vaccination. (streetinsider.com)
Children and Teens Make Up Most Infections
Young people have borne the brunt of the outbreaks, with roughly 69 percent of cases occurring in people under 20 and about one in five infections affecting children younger than five. Hospital admissions have been substantial: health agencies report 151 hospitalizations this year, while, to date, no measles-related deaths have been confirmed in 2026. (streetinsider.com)
Vaccine Coverage Has Fallen Below the 95% Threshold
Federal immunization data show MMR coverage among kindergarten-aged children has slipped below the 95 percent level epidemiologists say is needed to maintain herd immunity. Nationwide two-dose MMR coverage in the 2023–24 school year was estimated at roughly 92.7 percent, and several states report coverage rates well under 90 percent, creating vulnerable pockets for rapid spread.

Outbreaks and Geographic Spread Across Dozens of States
Measles cases in 2026 have been documented in the majority of the country, with infections reported in 45 states and the District of Columbia, and multiple distinct outbreaks recorded. Public health trackers attribute a portion of cases to international travel and importations, and dozens of linked clusters have amplified local transmission in communities with low vaccination coverage.

Federal and State Response: Funding and Containment Efforts
Federal agencies say they have mobilized resources to help state and local health departments with outbreak response, including targeted funding and surge personnel. The Department of Health and Human Services and the CDC have provided millions in emergency support to jurisdictions facing intense transmission while expanding technical assistance for contact tracing and vaccination clinics.

Experts Point to Hesitancy and Policy Shifts as Drivers
Public health experts cite falling routine vaccination rates, growing vaccine skepticism, and policy changes that have sown confusion as key contributors to the resurgence. Observers and independent fact-checks note that mixed messages from high-profile figures and changes in federal advisory processes have undermined public confidence in established vaccine guidance.

Public health authorities underscore that the two-dose MMR schedule remains highly effective—about 97 percent protective against measles when completed—and emphasize vaccination as the primary tool to stop transmission. Officials are urging parents and caregivers to check immunization records, ensure children receive recommended doses on schedule, and to seek guidance from local health departments about catch-up clinics and community vaccination events. (cdc.gov)
The current surge has renewed scrutiny of state-level vaccination policies and prompted calls for intensified outreach in communities with low uptake. Health departments report that targeted school and community programs, rapid case investigation, and broad access to MMR vaccination are central to halting further spread and protecting infants and immunocompromised people who cannot be vaccinated. (cdc.gov)
As the United States approaches the end of the year, public health officials say the trajectory of measles cases will depend on restoring high coverage in vulnerable communities and sustaining rapid outbreak responses where transmission is active. Without swift increases in vaccination and robust containment measures, experts warn, the country risks losing the gains achieved since measles elimination was declared in 2000. (stateline.org)
